[MOC] Skid Steer Loader - Lego Technic 42100 Model B
eric trax posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi. Guys! :) The high pace in building agricultural models I imposed myself last year meant that I had to take a break. I need something completely different and new challenges. Then I decided that it would be interesting to build an alternative model for the official set. The limited amount of bricks always boosts creativity. The 42100 set doesn't have a B model at the moment. When I saw model of Bobcat loader build by my friend Makkes', I thought it might be a pretty interesting idea for an alternative model. However, I didn't want to build a typical skid steer loader. Looking through this type of machine, I found the Bobcat T870. It is interesting because it has additional links and support arms. For what? Well, to get the vertical lift path. The whole system eliminates the bucket moving back effect and this makes loading onto trucks much easier. I built a loader in just over two weeks. Scaled to the wheels gave a 1:9 result. From the first pin, I planned that the model would be built modularly. It caused me a bit of problems but I learned a lot and the whole construction contains 14 modules. I started by building caterpillars and I am very proud of them. Technic links are very well stretched much better than in model A. The model is not complicated but its construction gives a lot of fun for example connecting the caterpillars with the frame and then the drive. When I ran out of one cardan, I decided to assemble it from the available elements. I wouldn't be myself if I didn't take care of visual issues. I knew at the planning stage that I wanted to finish the cabin with pneumatic hoses as a cage. I added many details such as oil tank, distributor, radiator, muffler. When we talk about visual details, operator's seat is my favorite part. I am aware that the model does not use the full potential of the set. Only a Control HUB and three engines and some parts are left for use. I treat this model as a warm-up before the next one Marek, as usual, create building instructions for the model and of course he did a perfect job. The original application is not suitable for control this model, so I decided I would create another instruction for the BuWizz application so that everyone could easily configure it. Model dimensions: Length 42cm, Width 23cm, Height 26cm, Weight 2480 gram Drive 2x XL, arms lifting XL, tilting bucket L motor. The building instructions are available at: https://sellfy.com/p/dwatsg/ https://rebrickable.com/mocs/MOC-37222/M_longer/42100-skid-steer-loader/ Photos and video below. This is my first alternative model so I am interested in your opinions. -
[MOC] 42108 Set Alternates
TGBDZ posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi there! At the start of January picked up the 42108 set (Actually wasn't planning on spending money on more Lego at the start of the year but saw a surprisingly cheap deal for a new set and just couldn't resist it). Naturally, opened the box, went through the instructions and applied all the stickers to their belonging parts and started to work on new alternates without assembling the original set (Yes, I'm a mad lad :D ) And who would have guessed.. my first alternate was another excavator.. I hope that people don't get exausted of seeing another one but this set turned out to be a great part pack for creating a sleek and fully functional wheeled excavator! Functions: Working steering - blue gear on the back Adjustable front shovel - manually, can be locked in place Adjustable rear outriggers - mannualy, can be locked in place Rotating upperstructure - Black knob at the rear of the chassis Fully functional arm - controlled by 2 seperate knobs on the top of the upperstructure Chasis storn enough and with the outriggers and shovel extended it can support the whole weight of the excavator and lift it from the ground. At this moment this is the second set that uses the new Large linear actuator, and it just makes reach on this medium sized excavator crazy good If You want to build it Yourself - Instructions available here: https://rebrickable.com/mocs/MOC-38023/tgbdz/42108-alternate-wheeled-excavator/?inventory=1#bi (Or simply look for TGBDZ on rebrickable) For the next build I wanted to make something different that I haven't tried before.. After Some tinkering with the parts a bit I started to build a rather large structure using the larg 3x11 curved panel pieces and after creating a large bathub like structure I decided to make an articulated hauler. I had atleast 6 wheels, for the center joint I could use the turntable, large actuator should cover the lifting of the cargo bed - all the major issues were solved quickly and here is the result. Functions: Working steering - no HOG - the center of the cab is so close to the swiveling point that it's easy to steer by pushing on the cab sides Fully adjustable chasis/suspension - front axle is solid and together with cabin is rotating on the turntable located in the center of the chasis - rear axles use double wheel boogies that easily gets over small obstacles Functional and tipping cargo bed - uses large actuator and is operated by knobs on either side Cargo bed can be locked at the back to prevent unecessary spillage of goods And just like for the excavator - I think the original 42108 stickers add a lot of nice touches to the design. Instructions for the Hauler will be available soon. What should I build next? At the moment I'm thinking of making two models at the same time - 42108 has 8 aviable wheels.. Will see :) Cheers! -

Liebherr HS 8040
Porsche96 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Liebherr HS 8040 Specification Length 40s / width 23-29s / height 21s (32/18-23/17 cm) – without boom Scale: 1:18 Maximum height depending on the lenght of the boom I 70 cm – equivalent 11m II 87 cm – equivalent 14m III 102 cm – equivalent 17m IV 121 cm – equivalent 20m Weight: 2945-4014g Power supply 2xBB 8878 Controlled by two sbricks 2x M 3x L 2x XL Functions Driving - 2 Ls Track sliding - M Rotation of the uppercarriage - M Lifting boom by a winch – L Two winches for moving the bucket – 2 XLs Today, I’d like to present you a dragline excavator Liebherr HS 8040. I came up with the idea of building such a machine after watching a movie from Brick Creek exhibition. The whole construction was made in about two months. For driving I used two L motors, which power both tracks with ratio 1,67:1. Because of that ratio the excavator is pretty fast (maybe too fast for such a machine). Because of variable track spacing there is no space to add other gear reduction, while maintaining the stability of the structure. The tracks are slided by four small linear actuators, driven by M motor. The mechanism of retracting tracks is based on guides of three studs height and one width. They come into the undercarrige, based on two cnostructions made of 5x7 frames, and connected by the system of sliding tracks. Details in photos below. The uppercarriage is mainly based on frames, connected by liftarms and housing made of technic panels. For rotation I used M motor with ratio 120:1. Three winches are made in similar way: the string is wound on a sleeve on an axle, between two 36 gears, driven by 12 gears. For lifting boom there is one L motor, and for moving the bucket there are two XL motors. I used modular counterweight, like in the real excavator. In the lightest configuartion it weighs 319 grams and consists of a battery box and back cover of the excavator. The heaviest configuartion of the counterweight it weighs 1140 grams. It consists of the lighter configuration and additional battery box, cover and lead weights (8x70g), which are protected against movement while driving the excavator. Boom is a simply, durable construction made with liftarms. Most angular connections are „legal”, but because of the narrowing of the first and the last section of boom, not all of them are. But they fits with no problem. Boom configuartions: I) I + IV: 30s + 44s, max height of the excavator 70 cm II) I + II + IV: 30s + 21s + 44s, max height of the excavator 87 cm III) I + II + IV: 30s + 42s + 44s, max height of the excavator 102 cm IV) I + II + III + IV: 30s + 21s + 42s + 44s, max height of the excavator 121 cm I built two buckets: a dragline bucket and a clamshell bucket. The excavator can be also used as a crane, but while lifting heavier element it would require bigger counterweight. Before I started the building, I wanted to make something fully modular. I think it worked out :) Operating the excavator is not easy, it requires a little of experience, which I am achieving. This type of machine is designed primarily to dig below the ground on which it stands (f.e. dredging water reservoirs), that’s why it’s hard to dig from a flat surface.

[MOC] Liebherr R 980 Excavator 1:25 motorized
Brickzone52 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello Everybody Im happy to introduce you my Liebherr R 980 excavator scalemodel 1:25. The whole excavator is fully motorized with power functions. The goal was to combine the motorized technic world with the usual lego bricks. Was not that easy because of the weight. This beauty will be for ever with me, thats why i also builded up a box as you can see on the pictures. Let me know what you think. :-) Best Regards from Zürich Switzerland.

[WIP] Mini Mining Excavator
teflon posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello there! I would like to show you a (slow and painful) progress on my take on mini mining excavator. Yeah, the Liebherr 9800 R kind. I kinda like the model, the 42100 and Markus is my favorite Technic creator but ... Well, the model is just to big and too simple and I can see some lazy short cuts (having three motors in an arm). And I haven't even mentioned the price, which is hilarious. Sorry about the rant. So you can imagine my joy when I saw cyberdyne systems' Mini Replica. He clearly showed what can be done in small form factor. However I was wondering if fully motorized version is also possible. Here starts my story. I've decided to build roughly 1/2 scale model. Yeah, I can be lazy to and dividing by 2 seems easy enough. At the moment I am not into esthetics, it's more about function, so please forgive me some crazy decision. Let me show you what have I done so far: I've started with the undercarriage. Simple, two tracks and turntable at the top. Well, the problem is motorization and even the smallest gearing needs 2-3 studs. The results is this: I am trying to use as little space for gearing as possible. It's not elegant by far: Motors are hidden in the back: At this stage, the battery (I am planing on using 2x BuWizz) will be located in the upper portion and cables are going through the center. Is not optimal solution, but solution through the turntable with mechanical connection needs even more space in the body. Next part was the bucket. I've also choosen 1/4 cylinder, however I've found interesting idea for bucket teeth. I think it works just fine: The bucket is fully operational. Next thing was building an arm. I was just trying to mimic the 42100 in 50% scale. However transfer of power at such scale is problematic: Here is the whole arm: And this is where I got stuck. I need to fix side M motors, which at the moment are just lying around. BuWizz units will be located at right corners. I am using studded technique just to approximate size. Another problems are universal joint's. They tend to work at angles 0-45°, however the arm swings for 90°. Maybe I should attach motors at an angle. Or do some gear magic. Regarding gear magic - I have to much of them already. I guess the biggest future problem is how to fit in motors and subcarriage. Feel free to comment. -
[MOC] Lego 42100 Mini-Replica
cyberdyne systems posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Good (random time) everyone! I was fascinated by the 42100. So, as I still haven't got one, I've decided to make my own version, but a bit smaller... I came up with an idea of an extra small excavator with all possible functions on board. No RC this time, of course. Only manual controlling. The bucket was a hard thing to do. But this quarter-cylindrical piece and a rope served me really well. I tried to make it as close to the real set, as possible. All the pipes, railings and barrels were recreated in my replica. The mechanisms inside the haul are both simple to understand and hard to invent: First boom section is raised via small linear actuator placed inside superstructure The same LA lifts the second section Worm gear to turn the levers system which tilts the bucket The bucket can be opened by pulling the rope Big turntable supports the superstructure. I don't really know what else to say/write. So the video is at your service. This video is a bit humorous. I hope, you would like it. Thanks for watching! -
Volvo H9X Specification of the excavator Length 60s / width 31s / height 20s (47/24,5/16 cm) - without excavator arm Max dimensions of excavator arm: 60x35 cm(length x width) Weight: 3637 g Front suspension: none Rear suspension: none AWD Steered both axles Power - 2x 8878 BB 3x M 4xL 2x XL 3x Servo Specification of the trailer Length 55s / width 25s / height 17s (44/20/13,5 cm) Weight: 1398 g Power: 1x 8881 BB 1x XL Functions Driving - 2x XL Steering - M Gearbox - M Lifting the blade - M Excavator rotation - L Movement of the arm - 3L + 3 Servos Lifting the trailer's tipping bed - XL Today, I want to present wheeled excavator Volvo H9X with trailer. Model was built for Lego contest „Build the construction machines of the future”. Later it received many improvements… In short: it is wheeled excavator without operator’s cabin. I didn’t pattern the model on any real machine. As a scale I took Claas’s wheels. For driving there are two XL motors, which drive the 4 wheels, through two-speed gearbox. First gear ratio is 5:1, and second 1,8:1. The gears are changed by M motor and two 1x7 racks. Both axles are steered by M motor with gear ratio 3:1. In the front there are blade, driven by another M motor. In the upper part of the excavator there are three comperssors for three pnematic functions. First, which drives the four big pnematic cylinders, consists of L motor and two pnematic pumps. Next two compressors are the same (L motor + one pump) and they drive the pneumatic cylinders for moving second section of the arm and the bucket. The valves are steered by three Servos. For excavator rotation I used L motor with gear ratio 155:1. In the front there are double Led lights, powered by a switch. The trailer is a simple liftarm construction. The bed is tipped by one linear actuator driven by XL motor. It is powered by switch, because of lack of free channels on the IR receivers. Gallery

Hello Everybody My Name is Dani, im a 36 years old LEGO fanatic from Zürich Switzerland and im a brandnew eurobricks member. ;-) Im proud to introduce you my Liebherr R 9150 excavator in the scale 1:13. Yeah i know, the mining machines from Liebherr are white in real, but i like the yellow Liebherr color design much more. It is „only“ a scale model and has no functions, motors etc, cause the construction is just too heavy. I dont know the wheight exactly, but i think its about 40 pounds, this thing is HUGE. As you can see, i used alot parts, only for the black track-chains about 1200 pieces. I worked on this Monster since 3 years, of course with a lot breaks between. Effort in hours: i guess about 300. Please let me know what you think. If you have any questions, just ask. ;-) -

[MOC] RC Excavator powered by BuWizz
Anto posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
One BuWizz, it's good. But two, it's better, because you can make MOCs having 8 functions! I have already done a full RC compact excavator, but with LEGO IR receivers. I wanted do make another excavator without the gearbox allowing to choose between the rotation of the arm and the pneumatic pump. Furthermore, the M motors were just enough powerful to move the arm. On this new excavator, it's different. I tried to make the mecanic as compact as possible. And the arm is controlled with more powerful motors: 1 L and 1 XL. So now you can... dig on gravel with a GoPro attached on the arm, and the motors bear that easily! There is a good speed and so much power to do anything you want! For the design, I tried to cover the maximum and I kept a color scheme close to the one of my previous excavator. To switch on the BuWizz of the turret, you need to open the part behind the cab. The hood is also openable, but there is nothing interesting to see. ^^ So the functions are: -> Controlled by the bottom BuWizz: Left track (M motor) Right track (M motor) Blade (M motor) LEDs (of the cab and the arm) -> Controlled by the BuWizz of the turret: Turn table (L motor) 1st part of the arm (XL motor) 2nd part of the arm (L motor) Bucket (M motor) You have certainly noticed that there are shock absorbers. It's for the tension of the tracks. The LEDs: And the video! The BuWizz are in Fast mode and I used the app BrickController, done by @imurvai. It's perfect for this MOC! -

Hello! I show here my entry to the latest Lego Ideas contest: the Volvo Excavadrone. This project born in my mind in the middle of the contest: at the beginning I was thinking about a modular construction machine, but it was not something “special”. Then I started thinking out of the box, and a flying machine was born! All functions are manual: Arm and bucket movement, with 3 Las Turret rotation Solar panel movement Flipping wheels/propellers Detachable operator cab Independent suspensions The model was a runner up winner of the contest, so I’m really proud of it. I hope you like it too. -
Backstory: Ever since I emerged from my dark age I was mesmerized by Designer Han’s models – especially dragline excavator. I like all kind of excavators so I was slowly gathering pieces for it to buy instructions and build it. I have realized over the time that building from instructions is not entertaining for me and that I can build almost anything if I have the drive (and parts). I still admire Han’s models, but I know that I would be disappointed because of his design choices. Don’t get me wrong – I still like his work, but I don’t want to build it anymore. Long story short – I wanted my own dragline excavator with truck transport. Preparations: First of all I had to pick a reference machine, in this case Sennebogen HD 670 tracked crane. Why this one? Sennebogen because it is not very known and because of this fantastic die cast model: http://www.cranesetc.co.uk/library/rosreviews/203/203review.htm . Such models are very good because you can see the machine from a lot of angles and you can replicate small details from them more easily. The model is however 690HD and I have picked smaller 70 ton 670HD. This is because of whole concept with transport truck. The scale is dictated by wheels, in this case by wheels on truck and wheels on excavator as well. Since TLG is making only two wheels for tracked vehicles it is simple choice. With bigger tracked wheels the scale is 21,5:1, meaning that 49,5mm tires for truck are perfect fit. 690HD with the same wheels would be closer to 23:1 and we do not have truck wheels for this scale. Features: Undercarriage Real crawlers have either retractable tracks or dismount them completely when transported. In order to achieve that I had to place all motors to superstructure and use single battery box. As you can see from datasheet, the tracks can be retracted so they are not wider than body. To replicate it I have built it in such way that both tracks are very easily detachable from central piece that can be swapped for narrow one. Replacing this central piece doesn’t take more than few minutes, it is only necessary to take apart two liftarms on each side as seen in the picture. Another stud or two narrower tracks would be probably better, but I would certainly lose the ability to swap it easily. All four wheels are driven by two shafts from superstructure connected to M motors; final ratio is 9,265:1. Wide track Narrow track IMGP5236 Superstructure The superstructure holds six motors (4x M-motor and 2x L-motor) – two M motors are for tracks, 1x M motor is for slewing via worm gear on turntable (56:1) and rest are for winches. Slewing gave me quite a headache because of the desired gear ratio. The real machine can rotate up to 4 revolutions per minute so I wanted to replicate that. In the end the only viable solution was to use older turntable driven by worn gear without further gear reductions. I use train PF remote to start and stop smoothly. The usage of older turntable meant I had to shorten boom because of its less stability as it bends significantly more than new type. The A frame is fixed – the boom is raised by pulling floating pulleys with attached ropes. Bigger machines uses movable A frame where the angle between A frame and boom is fixed. The A frame can be folded down when the crawler is transported. A frame is Pythagorean triplet with beams length 29-21-20. There are 3 winches for boom raising, bucket lifting and bucket drag. All three are equally geared 5:1. Counterweight is detachable as on real machine, it of course holds standard Technic battery box. Cabin features opening doors and foldable walkway. IMGP5220 IMGP5222 Ready for work side by side Boom Booms on real machines are made out of several truss elements bolted together. There is usually lower boom section that stays on crawler when transported, then are intermediate sections in various lengths (2,9m, 5,7, and 11,2m) and then headpiece section. I wanted to replicate this kind of boom so I focused on correct shape of each section and size as well. This mean that the lower boom section is pyramid-shape: 5x1 studs wide at crawler side and 9x9 studs at opposite end. I guess not all connections on it are TLG legal, but everything fits nicely without any stress and thanks to it truss-like constructions it is very sturdy. The same principle follows at intermediate section, in my case the shortest one (2920 mm => 17 studs). Boom ends with headpiece that is quite similar to lower section but ends with two pulleys. They are of course not real pulleys as TLG doesn’t make anything free-spinning in that size but size was more important to me. The drawback of such modular boom is its weight; it is almost double the weight of boom that would be built in one piece so I had to stay low with total length. There are also two pulleys serving as fairlead so the rope dragging the bucket goes to winch from top, the fairlead pulleys are mounted on lever so they stay in same position regardless of boom angle. Headpiece side comparsion boom Bucket It is brick-build and its size is only guessed from pictures and its volume, I was unable to find any datasheets with buckets. Bucket Greebling, look and difficulties As usually I pay a lot of attention to greebling like railings, mirrors, cabin shape, lights and other small details. I really had fun with this model as it is quite packed with it. The biggest obstacle during the build was constant lack of parts. Together with truck and low-loader it is reaching 4000 pieces and I was even running low on both 2l and 3l pins once. I had selected yellow color at the start, green would be certainly better for Sennebogen, but I already had some yellow parts and green technic is very expensive. Beside that I have seen pictures of Sennebogen machines in various colors like yellow, red and blue, so I think it is fine. The whole internal build is very symmetric; the only asymmetric is gearing on left side for slewing and gearing on right for drag winch. IMGP5223 Playability Honestly, playability sucks. There is one important feature of real dragline omitted – free fall winches. Without it you can place bucket too close and drag it only few centimeters. Grabbing anything with the bucket is also very difficult. Drive and slew works very well though. Truck The truck is very loosely based on this real counterpart: http://www.ditzj.de/html/en/trucks/scania/wiesbr500.html i.e. 8x4 tractor with short wheelbase, 2 steered axles, high cabin and tower behind it. It is driven by L-motor and servo is used for steering. Both steerable axles use the same configuration like in my previous truck – 5l steering arms and hubs with 3 ball joints. There is of course Ackermann steering and different angle on both axles. Rear axles are connected to fake V6 engine. Cabin features two seats, IR receiver between them and steering wheel. Whole cabin can tilt to reveal engine. Gear ratio from L motor is 7:1 because it is meant to haul quite a lot of weight. The truck can be easily modified to low cabin version as the high roof is only held by four pins. The tower is too high then so it is replaced with bare battery box. The whole truck is quite heavy on front and it have sometimes trouble with driving when it is without load so it is possible to add ballast box on its fifth wheel. There is also coupling for draw ball trailer, but it is not meant for pulling. I think the most difficult part of design was not to copy my previous truck. The cabin is still quite similar, I’m aware of that, but in the end I’m happy with other small details that makes it different – flags on front, mud flaps, detachable roof, etc. IMGP5248 IMGP5249 Working fake engine Low cabin Ballast box Low-loader Low loader with detachable gooseneck is based on Motomat’s trailer because in the end you realize there is only one viable way how to build it – two technic beams with plates between. A little challenge was how to mount wheels without using single axle for both sides. The frame between wheels can be only 4 studs wide meaning the axle can be supported by 2 studs. I have used 8L axle with stop supported by thin liftarms. In the end the wheels are supported enough, they can rotate freely and you can take them apart without axle. IMGP5260 Lowloader with detachable gooseneck Instructions I have made instructions for dragline and truck as well. Lowloader will follow soon. Both will appear on Rebrickable soon, I will add link here later. Due to amount of work it took I will sell instructions for dragline for 10€ and truck for 5€. Lowloader will be free as it is not something trully mine. Both instructions are as usually PDF generated by LPub3D. Especially the dragline is compressed into as few steps as possible, with only 115 pages (~2400 parts), so if you don't like TLG instructions for beeing too easy this might be something for you.

Hello, I present you my latest model: Starting from the 42053 set, I decided to add some improvements and make it remote controlled with linear actuators and PF. The undercarriage is very similar to the original, with manual functions. Main mods are double wheels, and some aesthetic adjustments. The Power functions components are located in the upper-structure, except one motor which is in the boom. 1M motor for rotation of the upper-structure 1XL motor for the main boom 1M motor for the third section of the boom 1M motor for the bucket There is also a fake linear actuator to adjust the second section of the boom. I used this solution because this adjustable boom is more common in the real EW160E. Changeable buckets with quick-coupler: Access to the battery box: Power button with easy access: More photos: Video coming soon!!

[MOC] Full RC Compact Excavator
Anto posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This MOC was built after 2 other attempts, 2 years ago and these didn't work. (I can explain a little the reasons if someone is interested) The design was difficult to do because of the round shapes. But I think the result is so good. You tell me ! The functions are : Left track Right track Blade Rotation of the turret 1st section of the arm 2nd section of the arm Moving the bucket Rotation of the arm (right/left) Opening/closing the clamp (pneumatic) All the functions are powered by M motors, except the rotation of the turret. But there are 9 functions, and it is possible to control just 8 functions with the IR system. How it's possible ? It's quite simple ! A gearbox allows to choose between "rotation of the arm" or "opening/closing the clamp". The chassis is very compact. It has 4 motors and 1 IR ! The mechanism of the rotation of the turret is not visible (the turret is too compact ! ^^) The rotation is quite fast (not too slow). Here you can see the motor actioning the 1st section of the arm. The motors of the 2nd section of the arm and the bucket are placed inside the arm. The last motor is placed in the middle of the chassis. It actuates the gearbox and you can choose the function to activate. With the clamp, there are a bucket and forks. -
LEGO Technic MOC Excavator
LEGO ADAM posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
A month ago I decided to make an excavator, first I was thinking about a mechanical powered one, but later I realized, that The mechanic cylinders are not that much powerful as I need. So I decided to do a pneumatic powered excavator. I had to buy the Lego Technic 42053 excavator because I needed the two biggest pneumatic 19478 cylinders to lift up the bang, one for the arm and fourth to move with the bucket. This excavator is based on pneumatic system v2. Its half rc and half manually controlled, that's sometimes hard if you work with it in terrain. In a few months, I am planning to build an updated fully rc version. Here is the video of the excavator: Parameters: length: 36 cm Max dig deep: 18cm Width: 17cm Max speed: 0.28km/h Weight: 1320g Electric motors: 3 the tracks mechanism The cabin -
[MOC] Bucyrus RH400 Mining Shovel
sheo posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I would like to present a 1:48 scale model of one of the largest hydraulic mining excavators in the world. This machine has been previously known as Terex O&K RH400 and Bucyrus RH400, and currently it is called Caterpillar 6090 FS. However, this model uses the preceding Bucyrus livery. The model has the following remotely controlled electric functions: Propulsion; Slewing; Boom operation and opening of bucket; Rotating cooling fans; Folding ladder; Retractable service station; Lighting. The model has a remotely controlled gearbox which distributes motor power between two sets of functions. The scale of the model is minifigure compatible. Thank you for your attention! -

Hi Guys, just signed up Eurobricks, I am not new to this website though. But glad to be able to discuss and share with lego builders around the world :) Here is my recent work, a transformer (actually it is more like an animation )check out and give me some feedback :) Axcavator - Lego Transformer by David vc, on Flickr -
[MOC]2 motor wheel excavator ver.2
msk6003 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Old topic link. After 3 month of topic, after 3 years of old ver.1, FINIALLY finish ver.2 model.(because I have lot's of other work lol) Anyway, see video first. I will upload photo later. Function is same with old version but work with ONLY 2 L motor insted v1's 2 M motor. Function is selected by upper structure poistion. 1. Drive Forward when arm point forward, backward when arm point back. Faster than v1. 2. Steering Different with ver.1, Steering working when arm point right(old left) 3. Dozer blade up/down Um... can I say that is up/down? Anyway, working if arm point left(old right) 4. Turning When remote's blue lever is forward, turning upper structure. 5. Bucket/Second arm When remote's red lever is backward, bucket and second arm start working. Simple than v1 and move larger than v1. When remote;s red laver is forward, under structure function(function 1~3) is working. 6. Main arm When remote's blue lever is backward, Main arm is working. Slower than v1 and move larger than v1. Entire excavator is much smaller than v1 and move little more faster. and used so much pinhole with 1L pin -
[MOC] Volvo excavator [video online]
steph77 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Here I am again. This time the subject is one of the very usual kind: one PFS IR commanded excavator. They are many exemples of perfect excavator on the web...but I just wanted mine, of my own design. So I study it from A to Z and I had to answer many of the questions that many people answer before.Surprisingly, I do not answer the same at some of them :) But first this is what we are talking about: This model as been design in one only goal : a maximum of fun to play with it. In order to match that goal, each and every motor Is directly connected to each function. No mechanics in there. The function are ultra classical : drive, steer, rotate and the 3 movements of the arm. I make use of L motor for the tracks and lifting main arm. Other are medium size motors. I also choose to keep it as compact as possible. The main issue I find on many creation on the web is a too big body resulting in a too big arm. Too big arm need lots of power and often be very slow to move. I try to get what I think is the best compromise in size and use of existing motors. (No pipa I do not have RC ones :) ) The tracks gives the global scale. As you see the BB is in the lower part of the structure. This is due to compactness of the upper part but also for better design of this last spoken upper part. As the excavator rolls only on flat surfaces, no use of any suspension in it... view from the downside the tracks are well integrated, and even with the BB there is a good ground clearance of 3T wich is very good. I also try to implement good action range at the arm: And also small details that makes it looks good, like 3 sets of lights, toolbox, ... Back view, easy acces to the BB to swictch on/off and replace (often:) ) batteries The top part is designed so replacing M motor by Large one is easy (I do command two of them, awaiting arrival) So here it is, not the Moc of the year for sure, but sometimes it's good to achieve some simple goals. As expected and designed for, this one is very fun to play with. Hope you'll enjoy it Steph. -
The Lego set 42030 Volvo L350F is one of my favorite sets. I love the playability, but I wish there were more Volvo vehicles from the same series of earth moving vehicles that were equally playable. I happen to have a second L350F bucket kicking around from a second set purchase to make a A40 dump truck. I wish I had the Lego motorized excavator, but I have parts and this is Lego after all, I'll just make one. The first check in my mind is the bucket size. The L350F bucket is a spade nose rock bucket with teeth and segments. In real life this bucket is 13 feet wide and holds about 9 to 10 cubic yards. The EC750E's largest bucket is a general purpose earth moving bucket with a capacity of 9.34 cubic yards. It's width is unspecified(in the EC750E brochure), and while it will not be a spade nose bucket, the volume is close enough that maybe this could work. The first thing I've done is to figure out if/how the loader bucket could be used as a digger bucket. My initial scale is 1 stud width = 6 inches based on the 750mm grouser being 30" (2.5') or 6" x 5 being a good match for the Lego track being 5 studs wide. We'll see if I stick to this roughly 1:30 scale in the end. I'm going to document the build here: http://cloudslego.blogspot.ca/2017/ and discuss the problems that come up in this forum. Here is the first proof of concept on the bucket/arm/boom.
