  1. Here is my idea for this comp. My excavator a going to be as small as I can get it with all functions inside of it so no external hose and pump. I'm not going to base it on a particular model but just get it to resemble something like one in general. I've started with the boom and dipper arm so here is my first concept, maybe it will stay like it but its early stages. Its 2 studs wide. The biggest challenge is the 3 studs of extension from the small cylinders and getting them to achieve more than that. Boom and dipper arm raised Boom and dipper arm reached down And Bucket to body All thoughts welcome.
  2. Following up on the Zorex-220 PF-excavator, I found that there were some things that could be improved. Inspired by the colour-scheme of the USA-based Link-Belt Excavators, I started designing a new excavator. Allthough the principles and scale are basically the same as the Zorex, there are many differences: * Link Belt is based on a real existing machine, Zorex is just a typical excavator* Link Belt has fully studless chassis, completely hiding the drivetrain inside the chassis, while maintaining the suspension* Improved driving and slewing thanks to a roller.* Uses L-motor for slewing* Openable cabin-door, cabin-roof, superstructure-side-doors and opening top.* More detailed interior* Greebles mimicing the insides of the machine* Improved scaling by extending boom and tracks Link Belt & SBrick Some weeks before Lego World 2014, I was contacted by the Sbrick-team, asking if I would like to demonstrate the Sbrick at Lego World. They sent me the Sbricks and this excavator was chosen to be the test-model for there prototype-Sbricks. The tests at Lego World turned out succesfull, the model and the Bluetooth-controlled Sbricks performed well. Using an iPod Touch as controller, there was no interference with the many PF-controlled models there. Ans the Sbrick-system allows you to controll the speed of the motors, making the controll very precise and more realistic. So when I started making instructions, 2 versions had to be made: 1 for the PF-version and 1 for the SBrick-version.

  3. Hi guys! Herre is my entry for the pneumatic contest. It's a volvo wheeled excavator. I was not really happy witthe new volvo excavator o I have decided to make my own Fonctions are: (Frame) HOG at the rear of the chassis; Rear stabilizers; Front blade (Turret) PF pneumatic pump operated by m motor First boom section (large pneumatic cylinder) Second boom section (large pneumatic cylinder) Bucket (Medium pneumatic cylinder) Here are the pictures: I hope you like this if you have any questions don't hesitate to post! Have a good day!
  4. Here are a few examples of what you can do with the Volvo EW160E (when it's in stores within the next few weeks!) A trailer: Forklift: Broader/Twin Tyres (preferably those from 8235 Front End Loader for example!) Grappling Claw Small Bucket Scoop Anything else you could imagine? Regards, Ryan J Smith.
  5. Here's my model of a classic Liebherr exavator. I'm not overly happy with it, but my primary goal - full remote control of all pneumatics with a high degree of accuracy - was achieved. Oh, and that custom LED beacon is available here: Photos & reading:
  6. Please note: this is not my creation I was aimlessly looking at Lego Technic stuff on youtube and came across this: I haven't found it on here, but I thought you guys would be interested to see the mechanisms, as they look very complex for such a small model , plus the fact it looks so cool It is also vote-able on cuusoo: Thoughts?
  7. Just an excavator fully operated from its 3 exhaust. It has 4 functions with hood to see the gears , rotation, first arm with 2 small L.A. and second arm with another small L.A. for the arm-bucket combined function. Maybe it would be nice to make instructions and a video. Forgive the photos I have neither my camera or my computer thank you.
  8. I had unfinished the MOC and this is the perfect excuse to finish and make it better. Let me know Jim if there is something wrong, there is an old topic about it but I never finished it.
  9. Hello guys! I decided to participate in the [TC5] Challenge, and for this challenge I'm using 8071 Bucket truck And my C model is a Wheeled excavator. I wonder why does the TLG always make tracked excavators instead of wheeled ones. Functions: Working Steering via the gear on the back Front grader can be raised up or down Feet on the back side can be lowered, and raised Rotation of the upper structure via the gear on the side Boom can be raised and lowered Bucket is fully operational too Here you can see that functions are controlled by yellow gears on the right side of the excavator. The brown gear at the back controls steering. Front grader and rear feet are controlled manually. Close up shot of the rear feet and a closer look of the bucket And the spare part photo - 55 parts left Video of functions can be found here (Older version of my model is seen in the video + sorry for the low quality)�� Leave comments and tell me what you think. Good day everyone!

    Hello everybody, please read carefully: as I only had 3 hours to play with my legos I came out with this "non serious try" , it's not intended to win, not to compete at all, I simply had fun doing it and from the bad picture and the "too many" left over parts you can guess I didn't try hard!! But there it is :grin: Sets used: + Hopefully something like this so there we go now! Sorry for the bad quality, taken with my Ipad. I'm off for my holiday now so won't be able to make better ones, neither to work or modify the moc itself! adjustable legs and foldable tracks as the real one!!! It can adapt to rough terrain aswell! OMG it can climb a 42000 tyre!!!! No gears involved as otherwise it would be too let's keep it as "low profile" :laugh: It can also bend forward! I know it looks like it's get on its knees.....but NO! Here the left over parts! Too many as you can see....I really should have tried harder :cry_sad: Thanks anyway, next time I'll make sure I'll come out with something nicer and more "professional"
  11. Hello, after years of only reading occasionally at Eurobricks it is time to present my latest MOC at Eurobricks: A caterpillar 365C ultra high demolition excavator. (If the youtube video disappeared: )It started with excavator 8043. But I did not like the bucket, because playing with this bucket is difficult. In most cases LEGO bricks will not get into the bucket but will just be pushed away. So I searched for alternatives and I came across demolition excavators. A LEGO demolition excavator would be great. And this demolition excavator should be able to demolish a LEGO house, this would be incredible. But is this possible? I realized quickly: this is not just a 8043 modification, this requires a complete new design. I started with the jaw. This has to be very small. If the jaw is too long, it will be impossible to breakaway Lego bricks. And the jaw must be turnable about 180° to demolish ceilings and walls at different heights. The clamping force should not depend on the angle position of the jaw, bricks should not drop from the jaw when the jaw is moved. After some trials I found a solution using a string (well visible in the video). I built a prototype with this string solution and made a trial: will the clamping force be high enough to enable the jaw disassembling a 1x8 brick? Yes! The clamping force is just enough. So I could answer the question of principle: it is possible to demolish a LEGO house with a LEGO excavator. As the next step I designed the bucket arm. This should contain two power function M-motors and friction clutches for closing the jaw and for moving the jaw. For both functions maximum power is required without overstressing the M-motors. The bucket arm should not be wider than 5 studs. I took some time, but the design of the bucket arm was not so difficult. Then I designed the undercarriage. I adopted the design principle of Jurgen Krooshoops 8043 modification and put the gear reduction into the undercarriage. In comparison with the undercarriage of the 8043 I designed a considerable longer undercarriage. Now the most difficult part: the upper structure. Main task: lifting the boom. As a first trial I used three linear actuators parallel. The upper structure was made mainly of liftarms. During the first trial I heard a lot of clicks, but the boom did not lift a little bit. I enforced the gear box, but all subsequent trials just ended up with ugly noises. The required force for lifting the boom was just too high. So I increased the distance between the lower linear actuator bearing point and the boom bearing point. So there is less force necessary for lifting the boom. But now the adjustment range of the linear actuators is not sufficient for lifting the boom vertically. So I added two additional linear actuators to archive the required adjustment range. In total I use now 4 linear actuators for lifting the boom. I designed the gearbox inside the upper structure following these principles: - use of technic bricks instead of liftarms wherever possible - bearing of gears on both sides of the gears, it must be impossible for gears to move apart Next trial: the XL-motor is moaning a little bit, but the boom is lifting. Hip, Hip, Hooray! Now I started with detailed design of the upper structure, finally 2 XL-motors, 4 M-motors, 4 IR receiver and 2 battery boxes have to be placed inside the upper structure. Two battery boxes? Yes, I need the weight of two battery boxes as counterweight and the electric power should last for at least one day during an exhibition. As I did not have all required parts in yellow I built the excavator with available parts. So right now the excavator design was finished, but the excavator was multicoloured. As next step I built the excavator in ML Cad. During this step some improvements were implemented. After finishing this I knew exactly which parts I needed and I bought them. And then I did something I really like: building a MOC following a building instruction I created on my own. Last I created stickers and then my demolition excavator was complete. This demolition excavator was designed for demolishing a LEGO house, so I needed a house for demolishing. Of course not a single family house, I needed a tower building. Based on pictures of real tower buildings and a reasonable floor plan I built a tower house in ML Cad. And then I bought the worst available parts, the house must not look like new, it should look like ready for demolishing. Building the tower building according to the ML Cad building instruction was not difficulty, it just took quite a lot of time as 11,000 parts had to be assembled. At the end tower building and excavator were ready just in time for the LEGO FanWelt Exhibition. Kind Regards Ludger PS: Demolishing the tower building with the excavator is fun for hours.
  12. Like the 8043 but with 6 L.A.s. Tracks, rotation, gearbox are ok, I have to build a lighter bucket, carry trasmision to the second arm and think about a special linkage to achieve more travel for the first arm, a lot of work but very entertaining. Maybe I could build a normal undercarriage in the case someone want to build it.
  13. Hi, my name is Tommaso Bocchietti and this is my first LEGO creaton. Please vote me at: *link removed*
  14. Hi Folks, Many, many years ago I started the process of creating instructions for one of my models, the JCB JS220 excavator. Unfortunately I was unable to convert the complex CAD files to instructions due to technical problems, but Eric Albrecht (Blakbird) has stepped in and made it work. So after an incredible amount of work from Eric and myself, it is with great pleasure I finally announce they are ready, and can now be downloaded. Eric has done an amazing job on the rendering, and the instructions are of the highest quality. They can be downloaded from Crowkiller's website for a small charge at the following link; http://www.crowkille...F-JCB-excavator Enjoy! Jennifer
  15. Hi! After completing my Swingloader Mk III, I haven't had a lot of time to build something big, so I tried my hands on something small instead. I made this a couple of days ago, trying to get a lot of technical (albeit simple) features into a small package! I tried to make it a scale comparable to that of this years' constructon crew set, and here it is next to that set's excavator Most of the features are explained in the next picture, except the second stage of the dipper, which is lifted manually. Here is an underside shot, showing the track extending mechanism. Not the sturdiest of designs, but more than enough. Higher resolution images can be found in my Bricksafe folder I will be making an LDD file, if anyone is interested.. Lastly, I actually made a video BEFORE making the topic, so here you go, showing all features (I think)
  16. Hoi hoi Here the photo's of the Atlas rail-road excavator for narrow track rail. The model is based on the Atlas 220 WWR "Sterke Hufter" (Strong **hole) Normely it's working under the rail catenary and have no problem to lift 10 ton whit the boom completly set out to the frond. I don't now or there realy exists a narrow track model but this model is made for Lego rails. One thing that is not correct on the model is the pneumatic cilinders, The real model have underlying cylinders, On my model the are situated on top of the boom. All the boom functions are pneumatic, The rail wheels can go up and douwn by small air cylinders. It roles and turn manual, Made als some equipment for it like a rail stabilizer, weed control unit, a hook , excavator bugget small and midium, and a jip.. Hope you like it. ps hope my post is easier to read if not pleace say so ! Part 2 Loading a truck whit air The weed control unit in action The rail stabilizer in action More photo's you can find here. Muddy
  17. Hi all! [Edit: I'll post a video and real photos later] I got some time and I made a 42004 alternate for the Rebrickable December Competition. It is a small, wheeled excavator, which is slightly based on the 8419 (like the main boom mecanism) My first intention was to keep a bucket and to give it an use (not as decoration). An excavator looks me the most common application for a bucket. I used the small bucket because I think it has the right size. I used all gears -as gears -. The features: -Steering (HoG) -Main boom raising and lowering (Worm) -2nd and 3th section movement (Worm) -Extra movement of the bucket (Manual) -Turning (Turntable) The body is a bit unfinished, but with not any leftover beam, I couldn't get it looks better. For me, just as for many other Technic builders, functionality is more important than looks. For it size and the available parts, I think it's pretty good. I had only 10 unused parts, of which 8 pins. What do you think of it, and do you have any suggestions to improve it? Greets, Fresko
  18. This Posting is dedicated to - the TLG which offers this great set - Juergen who has build the ultimate 8043 and also has posted some small improvements to the original design - all of you who are somehow disappointed by the original design (out of sync LAs, hard moveable boom etc.) IMHO the original design is awesome and needs only very few (and cheap!) and punctal improvements to work like a charm. Remark: some of the mentioned improvements come from this vey helpful posting from Juergen (http://www.eurobrick...showtopic=45133), but i have not installed all of them. well, here is the list of improvements i have installed: 1. Switching driving-rings (from Juergens post, s.a.) Juergen: The first time I built the 8043, it had some trouble switching the driving rings. Most of the time, the motor had to run twice to completely flip the switch. So I geared down the motor by replacing the 2 16-tooth gears with a 12-20-bevel-gear setup. I also replaced the blue axle-pin with friction (step 35, book 1) with a tan axle-pin without friction. 2. Rubber belts to help the boom (from Juergens post too) Juergen: To get some weight from the boom, I added rubber-bands. They reduce the friction the LA's which is caused by the weight of the boom. I didn't think of this myself but read it in this eurobricks-thread. (I have choosen 6 black rubberbands ("Black Rubber Belt Medium (Round Cross Section)", part-no x37 at Bricklink), which work very well and look IMO better than the blue ones). But this doesn't destroy the very good aestetic of the model and make the operation of the main boom very good - also with the standard batteries! This MOD can be also applied very easy after finishing the build - so you can compare the effect. 3. Improving the rotation point ot the original bucket (Stolen from barman) (in both pictures: left the original, right the improved version of barman) It improves bucket operation a lot and is very cheap and simply to build from the pictures in its brickshelf folder: http://www.brickshel...ry.cgi?f=432777 - very recommended. 4. Making the left track running smoothly This is done by replacing the 4L with stop axle in step 36 (book 1) with an axle 6L - this prevents that driving axle from canting under load 5. That's it. With all this small and cheap improvements i must state: i overall prefer the "original" 8043 over the ultimate of Juergen, though the latter one is an outstanding mod and very well done - chapeau Juergen! But why i prefer the original: simply because of the cleverness of the mode-switching between arm-operations and propulsion/slewing - which allows 6 functions with just 4 motors. Well, of course the Ultimate of Juergen is a "cost no object" excavator and is a little bit more realistic to operate because all can be done simulaneously, BUT: this is not really necessary - the playability of the original design (with the improvements listed above) is also very high and has only very small restrictions - quite ignorable IMHO. But this mode-switching design is really clever and makes more fun to build and view and operate as the 6-motor-version - at least in my personal opinion ;-) Or let me cite Juergen: "One of the reasons for me to make this topic (Kumbbl: see link above) and video is to show that this model, when constructed correctly & precisely, operates quite well" SO: IMHO its is not really necessary to spend a lot of money for additional motors, receivers, controllers to make this model work well, some bucks for some cheap parts are sufficient. But of course there is one basic and important requirement: it is essential to build this model perfectly, means controlling after each step if all(!) gears and axles are running perfect and smooth - and "perfect" means perfect!! and the main boom LAs must be installed in perfect sync (but then IMHO it is not necessary to switch some gears or something else...just build as in the instructions) Finally: chapeau to the designer of this set - on of the best in the studdless aera! BTW: this praising is from a man who normally prefers pneumatic over LAs ;-) Just my 2 cts.
  19. Recently I had the idea that I can use the camera while building. I decided to make a video with pictures taken during the build. I used the Canon EOS 550D and EOS Utility. First I built 42011. I made about 450 photos. This is the result of this operation: Another set was 42006 Excavator. In this case, I made a 1450 photos. The mistake I made ​​was half the battery. In the film, if you can not see when I take out the battery and Stand the tripod. Photos were taken at night with a fluorescent lamp. A little strange being built with the knowledge that the picture is taken every 5 sec and you have to take your hands :). Significantly increases the time to build if you shoot images. Here is the result: I think to build all the sets in this way. For sure I have to build 42000 and 9396. Here a link to my YouTube channel: Sorry for spelling errors
  20. So, I decided I'd take the plunge and attempt the zorex-220 build from the uber designer that is Jurgen Of JTC... And so I bought his instructions and after spending almost 7 hours sorting out my spare parts and realising that I had to cannibalise my 42006 and my modified red excavator ( the one with the weird dipper set up from like 2009, I forget the set number) I discovered I had about 90% of the parts... A few stops to some parts sites and a stop by WASSERMANS shop as recommended on here for a 8878 rechargeable batt pack, once my orders arrive il be in a position to start building it.... Il upload some pictures as and when I'm building, but however, can someone help with picture sizing guidelines etc to keep me out of the Mods firing line please... Word of warning on the upcoming build...I'm not a stickler for sticking to certain colours, so I'm just prewarning you guys, I know some of you are purists and pick up on tiny details ;) so be warned! Take care guys :) Gareth
  21. Hello again! I made a small moc some time ago, but I didn't had time to publish it (due the buzy weeks at school). It's al little pneumatic creation (my first fully pneumatic), with 4 functions: A 3-section boom and a little backfill blade. Naturally it works with 4 valves. For the air pressure, I used 1 external big, manual pneumatic pump, because I didn't want that the model included batteries or other electric parts. Off course you can make an external electric pump. It was a challenge to hide all the tubes in a small space. And to end, a video: Please tell me what you think and how I can improve it! If there should be enough interest in instructions, I can make them. Greets, Fresko
  22. Hi guys Maybe someone already noticed my new equipment in the heavy machinery post . This time I build a compact excavator from the producer Liebherr. I finished it a few weeks ago. Here is the original: And here is my Lego version: PF Features: 1M Motor crawler left 1M Motor crawler right 1M Motor rotation 1 XL Motor main boom 1L Motor front boom 1 M Motor bucket 1 M Motor tool function 1 1 Micromotor tool function 2 (rotation) 4 IR reciever 2 battery boxes And some pictures: In this picture you can see the "compact" aspect And finally some tools: More pictures you can find here : Flickr Brickshelf And here is the first video. actionvideos are coming soon. Hope you like it

    Walking excavator

    After completing the autopump i realized it would be very usefull in a construction equipement. But i wanted to build omething special, unlike the usual classic machines. This is why I chose a walking excavator type of a vehicle. To lift and tilt its legs I used pneumatics, because they are better in routing tubes over the complex joints on which the machine rests. For operation of the arm I chose LA's due to their ability to accurately move loads with little jerking. So here's the excavator nice and tightly folded. The legs are spread and the boom begins to lift: The four legs are than lowered therebye lifting the whole excavator up some 10 cm: As you can see each of the tracks has its own M motor, the total number of motors being 11, all M type: Feeding on some bricks: And spewing them out: The underside of the bottom showing the two autopmups used to lower and spread the legs: And the video of excavator in action: All in all I am quite pleased with the model, especially the pneumatic side of it. Its really fun to play with it, lift it up and dig out the bricks. There are some things bothering me though: The legs bend too much sideways The speed of the superstructure is a bit fast Pneumatics are unstable unless in maximum lowest or highest position Long wheel base makes skid steering hard What'ya all think?
  24. Hi guys, I've just brought the great 8043 and really enjoyed building it. However, I'm sure I've made a newbie error somewhere along the line as when I lower the boom it starts to have interference with the black 12T double bevel gear before the LA's have completely retracted (there's still about ~10mm of movement left on the LAs). I've posted a picture below which shows the grey hinge about to start hitting the gear. Has anyone come across this issue before? Note: in the picture below I've put the LA's out of the way to make the picture clearer
  25. Hi everyone. I'm new to eurobricks and before the presentation of my new MOC that is going to be finished in weeks, i want to show you some of my previous models. I think that describing all of the creations doesn't make sense, so I will show you only my best (In my opinion) MOCs: My latest creation - CAT 963D crawler loader. Very simple construction, just 4 PF M motors, 2 IR receivers, rechargeable battery box, some gears and stuff. But I really like this model, it works smoothly and it's a big fun playing with it. (Image is a link to the gallery) _________________________________________________________ Another model, Liebherr HS-855 dragline excavator. Big model, difficult to build. But it worked quite good. It was hard to learn how to dig with it :) It had 7 motors inside, 2 battery boxes and 3 IR receivers. Only cabin lifting wasn't remote controlled. (Image is a link to the gallery) _____________________________________________________________ Another yellow machine :) Liebherr LTM 1050 mobile crane. My favourite one. The mechanics of the model were very complicated, but as I remember, everything worked quite good. 7 PF motors, 3 IR receivers, battery box, some pneumatic stuff. (Image is a link to the gallery) ______________________________________________________________ In my gallery there are more models, but describing all of them here doesn't make sense. So, here is my gallery: Brickshelf Flickr And the YouTube channel: Youtube (make sure to subscribe to be up-to-date with my new videos ) If you have any questions - feel free to ask! PS. Is it posible to embed a YT video?
