Thank you all for your feedback. I never been a great fan of the studfull Technic sets on an aesthetic aspect only. But I however consider these old sets were the glory time of Lego Technic. Original models that have never been remade since, more than one or two alternative models per box... Good ol'time.

Hello Eurobrick I present you today a double rebuilt I have completed few days ago. This is not a real project, I needed to make a break from power functions and I had some spare time due to low workload. Back in 1994, Lego released the Universal Set “8062 with Storage Case”: One briefing case with instruction for 7 different models. I was 7 years old when it was released and unfortunately I never have owned it. One of the 7 build from set 8062 was a claw-mounted vehicle. In the main lines, this is a 6-wheeler, 4 wheels steering via HOG, with an arm raised through a worm gear and the claw, controlled from the side of the vehicle. I recommend you to visit the great and well documented Technicopedia website from Blackbird if you want to have additional info on all the models from 8062 set. Studless version: The first MOC is simply a studless rebuild version of the original model from 1994. The design is exactly the same: 6 wheelers (same wheels of course) with a massive claw and a massive operator cabin. The only additions are the seat in the cabin and the working light above the cabin. The functions are also exactly the same : - 4 wheels steering through an HOG placed above the cabin - Erection of the arm though a worm gear installed behind the cabin - Operation of the claw trough a worm gear and universal joint controlled from the side of the vehicle Modernized version This second version is made more with a 2018 standard. The design has not really evolved except the cabin which is smaller and moved forward. It is still a 6 wheelers with 4 wheels steering, but the HOG control is in the middle of the vehicle and the central axle has been connected to a 2-cylinder engine placed at the rear. The main arm is raised using a mini-LA and the control to open/close are now directly on the claw. It was not possible to install them somewhere else due to the mini LA and the motor. Here’s a digital view of the mechanical parts : The video : Bonus: Both MOC’s digital models can be downloaded by clicking on the picture just here below (Please note that I haven’t updated model after physical build, so they may contain building mistake). Convert old studfull sets to studless and then modernize it is an interesting process. I will probably try to make others in the future, between two major MOC. Thank you for reading!

Or use rubber band ? I like the side forklift, it is in my to-do list for more than a year now but full mechanical -no pneumatic- Maybe some day I will work on. Or a different version (see spoiler) It'a a good MOC, especially considering it is a C-model. I just have a complaint : The fork doesn't go to the ground.

@Rudivdk and @mocbuild101 Same Topic name, same inspiration but different project to come. I will grab some popcorn and look forward see what will happen

Thank you :)

To be honest I think I've just been lucky I don't exactly remember how I found this crane the first time. I suppose I had Youtube playing random videos and the "TU2-155 Delivery" one just appeared. "Oh wait, this is a cool thing to do with Lego!". After that it's the usual process: try to find info about the real machine, then plan, then specs etc. Not the easiest part when all website are in Russian. Youtube, first source for inspiration

Some month ago, I discovered the Сокол -80M (Сокол = Falcon), a heavy Russian crane with a lifting capacity of 80t on a two stages telescopic boom, thanks to another couple of hour spent on Youtube instead of working. See the video here (starting at 1:38) After some difficult search, I found that two variant exists, the first one is Falcon 80.01 and is mounted on a wagon for railway crash salvage and recovery, the second one is Falcon 80M which is mounted on a self-propelled tracked vehicle equipped with outriggers, able so to be also used in hard off-road environment . It is this version that kept my attention. The Lego Version This MOC is ‘inspired’ by the Сокол-80M more than a real scale reproduction. All the pictures are availavle on FlickR The transporter part is mounted on two track and equipped with deploying outriggers adapted from the 42009 Mark II Mobile crane. I had to modify them in order to avoid clash with the tracks There is 4 functions integrated in the transporter: Left track + Right track with a PF-L motor each Deployment of the outriggers through PF-M Extension of the stabilizers through PF-M These functions are controlled by a SBrick and powered by a single rechargeable battery installed in the cabin. The superstructure supports the main mast which is erected using two linear actuator. Due to the gear reduction (PF-L > short worm gear > 20T > LA) it moves very slowly but it works. I would really love to see one day Linear actuator twice the length of the current ones. Superstructure is installed on a 60t turntable and integrates all the functions required to operate the crane: Rotation of the superstructure through a PF-M Erection of the mast through PF-L Deployment of the telescopic part through PF-M Cable operation through PF-M These 4 functions are also operated through a dedicated SBrick powered by the battery. The only cable passing through the turntable is for the electrical alimentation The transporter and the superstructure are independent and can be separated. The assembly is done by simply clipping the turntable onto the transporter. A video : Good and to improve: Good : It’s like a mobile crane but more badass. Each transporter and superstructure can be controlled independently from the other Could have been done better : The visual aspect of the transporter and the crane cabin are not really perfect. I won’t lie, reproduce real machine at a mid scale is still not my cup of tea. What could be done better: Upscale it. Bigger, more space, more possibility. Thank you for reading

Well done. Everyday what can be achieve with Lego still surprise me.

It seems the only way to be fair to everyone is to be unfair to everyone in the same way. Give the Chiron to some one who didn’t event enter the contest: No one wins, no one loses, no one feels unfair. Did I mention I didn’t enter the contest and love to help? (Yes this is humour)

The lego's website states that rechargeable battery 8878 has an output voltage of 7,8V. The non-rechargeable are supposed to be 9V (6 x 1.5V) . I did not verified by myself the performance of each battery, but so far I did not saw any real diffrenece when using them. The rechargeable battery is my favourite too.

I initially wanted to use two cable (see below, sorry for my MS Word skills ) but tehre wouldn't be any advancatge so I came back to only 1 cable. To get back to the carrier, the same design was "supposed" to cover the three possibilities I studied (originaly posted on my Instagram). In the reality it is not reusable and have to be desassembled and rebuilt from scratch due to the number of motor, cable and other thing in it.

Thank you all for your feedback :) I don't have started thinking about a third prototype, but I may go back to a tracked carrier - I have to chose between something that look like the first proto or a vehicle inspired by a Foremost Husky 8 (here). And this this it will probably be a single crane with more function. Something like a log loader.

I am continuing to explore the fascinating world of the pipe transportation with a new prototype. You may already have seen it on youtube, I’m a bit late to post here (busy week-end). If you have a good memory, I did a first prototype on track (here) that had some limitation; in particular it couldn’t transport more than one pipe at once. The complete album is available on FlickR Prototype 2. For this second iteration, I started again form a white sheet to try something new : The transporter is now on tire with multiple axle steering for a good maneuverability and good translation speed (more adapted to road). I choose to keep two cranes for the consistency with the first proto. First advantage this allows making them smaller, as each crane support almost half of the weight of the pipe they don’t need to be reinforced and a mini actuator is enough to make them move. Second advantage is that the pipe remains horizontal even if not loaded exactly on its center of gravity. What’s inside ? There is 6 functions in this truck (5RC + 1 manual). Propulsion on axle 3 and 4. Steering on axle 1-2 and 5-6. The cranes : 1- 360 degrees Rotation. 2- 90 degrees Lift. 3- Cable. The truck was built from the center to the extremity, both crane are a copy-paste and are actuated by the same motors placed in the middle of the truck. Advantage: the crane move simultaneously and are always in the same position, drawback: you can’t use only one crane if you want to (I don’t know why you would have to use only one crane but well.) This was a choice at the conception because the goal of this prototype was to test the concept. With an alternative built it would have been possible to upgrade the truck so each crane have its set of motor , and the simultaneous movement is manage through the software (because yes, SBrick allows you to control several port with one command) Last functions are the additional lateral support that are deployed manually. They were added lattely in the building process (when I tried to install a larger pipe that clashed with the cranes), so I did not had enough room left in the truck to install the pneumatic line. Not a big issue in my opinion, I will do better next time. Good and not compare to the first prototype: Good Can transport more than one pipe Can load/unload up to two pipe in total autonomy No real length limitation Better road capabilities Not good Still requires a manual intervention to catch the pipe Range of operation : Cranes are not long enough to load the additional support. The dual crane are still not independent. Some improvements are still possible. So, project to be continued. Thank you for reading Edit: One additional word: in the video you can see a support vehicle. It is a not-so-good mini forklift only used to load the truck, It has been possible by the use of a 3rd Sbrick (both vehicle controlled through the same interface) and 4 M motors. Dedicated video here (yes I was terribly boring when I did the miniature ):

Aw yes yes yes, this is a really cool MOC. Great choice of tires, it reproduces weel the original look of the 60035.

Actually I don't really like the drilling head, but I made several try I didn't found how to make a good design in technic. Edit: Initially I wanted to use one of the Rover Wheel design in the folowwing topic, but I didn't had parts to do so, and did'nt want to order parts just for that.

The véhicule is correctly equilibred, but i think my table isn't horizontal. I will check that.

At the beginning of 2018, TLG has released a new series of Lego City sets, including the 60188 Mining Experts Site with a big drilling machine called The Crusher. It’s some sort of a hybrid between a tunnel drilling machine and a bucket wheel excavator. #Makeitbigger I’m not a big fan of re-build/improve official lego set but a take one CITY set and #Makeitbigger in TECHNIC is surprisingly challenging. (A good idea for a contest in my opinion). The Crusher XL’s MOC is not an exact upscale of the 60188’s Crusher, I built it like a “bigger” one, but still at minifig scale, with Bluetooth control through 2 SBricks and some power function elements: - 1x Battery Box - 6x PF-M Motors - 2x PF-L Motors - 5x PF-LEDs - 3x 15cm cable extensions - 1x 50cm cable extension The main differences with the original model: - The tracks are doubled and driven by a PF-M motor each. - It is composed of two parts. The lower part is the vehicle. It is built on a cross structure with track at each side. The 11x11 rack from set 42055 are reused to rigidify the assembly and support the upper superstructure. (LDD on google drive here) - The upper part is the superstructure. It can rotate nearly 300 degrees (the limitation is here to preserve the PF cable) and contains the electrical heart of the machine. The small PF-B battery box is place at the rear to be used as counterweight and completed with two boat weight (73090b);There is 4 motor and the 2 SBricks fitted in this little space to control the mains function. - The cabin is a reuse of the 42055 set. It fits well to this model and defines the minifig scale of the vehicle. The position has been forwarded for the operator to have a better view. - The arm is raised and lowered by cable actuated by a PF-M. A single cable is used between the two winches so it can accommodate the difference of position. - There is no moving counterweight (‘cause it is ugly) - The drilling head can tilt. It is mounted on a turn table and can turn to 360 degrees. The turntable is old and jam a little so the movement is not very smooth. Both drilling and tilting function are powered by a PF-L motor each. The Video : Possible improvements There are some points I initially wanted to include in this MOC but they wouldn’t have fitted in this scale. So I keep them in mind if one day I decide to build a Mk.2 : - 360 degree rotating track instead of a rotating superstructure: the challenge here was to find a means to control each 4 tracks separately (see picture below) - Telescopic arm: why not ? - Material belt conveyor between the dual drilling head like a bucket wheel excavator Thank you for reading :)

Deleted, already answered above

Sorry I totally forgot to answer last time (lot of work), but I’m very happy if you have been able to upgrade your MOC with the LDD I provide you

The prototype of the Porsche had also a black/white camo at its first presentation. Anyway I agree with the original dual blue scheme. The « original » color of the Bugatti.

If it can help I made this kind of clamshell bucket for an old MOD (here). The zip file here contains the LDD https://drive.google.com/open?id=1KIwTDoTSbYUCkDWG_1qWawXZpemxyxJ2

Just a quick input, Bugatti has unveil the Chiron Sport in Geneva yesterday. (The info on Bugatti's website here) Small improvment and new colour. Now, the BIG question. Will TLG make the classic chiron (blue?), or add two exhaust to make the Sport one (red?)?

This is not the most complex MOC I have done for sure. But honestly there is one big issue with this truck is that the differential clash with the gear of the closest axle when the truck is in rough terrain. I will make a try with stiffer shock absorber to see if it solve the issue. I'm working on the LDD file (so I can add it to the Axle Collection Tread topic) it will be easier to explain the issue.

Thank you all for your comment. A point I forgot to mention,there was already a bigger Commander made in 2010 by @andythenorth "Tri Axle" is the name given by Foremost i think to differentiate it from the old Commander C which was 6x6. But I agree with you, it is confusing To be honest I didn't know how to make a proper load for this truck, and the Saturn V fitted perfectly

Foremost is a Canadian company specialized in oil & gas, heavy oil, mining, water well and construction equipment. You can have here on Foremost’s website a complete overview of their activities and product. Note that @Erik Leppen is also working on a Foremost truck; the Delta III, which can be viewed here to discover a great modular big MOC. On myside, I prpose youthe Commander Tri-Axle. The main and only goal of this MOC was to test the “tri-axle” design. The Commander C Tri-Axle was launch in 2011 and is a 8x8 evolution of the classic 6x6 Commander C. “by adding a third axle to allow for an extended oilfield deck while maintaining low ground pressures. This also increases the maximum payload capacity from 60,000 lbs (27,216 kg) to 80,000 lbs (36,287 kg).” says Foremost. In the main line the truck is an all wheel drive articulated truck mounted on Terra tires, equipped with a 500hp Cummins engine, a 11m bed and a 58t winch. The full documentation of the Commander Series is available here. The MOC. The truck is a 8x8 articulated RC truck. The full Album is available on FLickR There is three power function controlled through a SBrick controller plus a manual one: 1 PF-XL motor for propulsion (redution 1:1) 1 PF-M motor for steering (12t-36t-Worm-24t) 2 PF-LED for headlight Manual winch with locking system The tires used are 68.8 x 40 Balloon Large. The front axle is only pendular, just to simplify the construction. The 3 rear axles are pendular and independent from each other. The forward axle has stiffer shock absorber to support the weight of the 2 motors and the battery box. The winch is manual and equipped with a locking mechanism. There is only few details in the cabin, it is actually hard to find pictures, it is a simple three seats cabin. The driver’s seat is equipped with some instruments. (the music in the video may not work properly ) Some Bonus. The Commander fitted with a "special" load for delivery: The commander fitted with gopro mount for outdoor filming: Nose 360 degrees mount Lateral 360 degrees mount (can bee fitted on both side) bed upper mount The aft cabin support used in the video has been included later so picture available Thank you for reading !
