Aleh posted a topic in LEGO Technic and Model TeamHello everyone! Before I start I want to wish all of you to stay healthy, survive and win the disease! Today at my birthday I decided to share with you my latest MOC. This is a brand new Liebherr LR 11000. From the previous model, it took only some boom sections and proportions. The chassis and superstructure built from nothing and were rebuild several times. Below please let me share with you some dry specifications of the model: - Crane is about 2 meter high - weights 5 kg - requires at least 5 big battery boxes for been fully operated - can be managed by 3 sBrick units. - has 10 PF motors (4 are in the chassis) - Has 9 pneumatic cylinders + a pump - Has a full-size V6 diesel fake engine like the real crane - Has 6 winches, 3 of them are installed to the boom like in the real crane, but none of the motors are on the booms. - Crane is able to assemble and disassemble back from horizontal to working condition without any human help. - Has 4 pneumatic features, three of them are operated from the cabin, two of them are operated from the operators work seat Now is hte time for it's features: - Driving and steering - one XL motor per each track. Torgue increased 1:25 - Slewing by 2 M motors - L Motor for SA Frame winch - L Motor for the Main boom winch - M motor for the luffing jib winch - M motor for the secondary hook winch - L motor for the main hook winches - Pneumatically adjustable operators cabin - Pneumatically adjustable derrick counterweight horizontally - Pneumatically adjustable derrick counterweight vertically - Pneumatically rising chassis for (dis)assemble. - L motor for the pump and V6 engine - Individual Sbrick custom profile - 3 Pair of lights: - Front LED - Cab LED - Main hook winches LED Here is the link to photos, I'll post some directly here: https://bricksafe.com/pages/Aleh/2020-lego-liebher-lr-11000 Bonus: Here is the performance of the superstructure stability without boom and without counterweight(!), only one battery box insalled for fotors activity. Boxes are full with batteries (24 pcs) Easy to fix the front suspension: https://bricksafe.com/files/Aleh/2020-lego-liebher-lr-11000/IMG_2983.jpeg/800x600.jpg 1,5 kg load.

Aleh posted a topic in LEGO Technic and Model TeamHello guys! At last I can represent to all of you my latest MOC. It's a Lego Technic Liebherr LR 11000 Crawler Crane. I tried to build a copy of a famous Liebherr-brand crawler crane. If to be honest it was my dream to build a human-high technic crane. This model is approx two meters high. It has five independent winches! Real crane has six, but two of them goes to one hook, what was not necessary to represent in lego version. Except string crane is build of 100% Lego. As a counterweight I used three big battery boxes in the superstructure and three ones in the additional counterweight carriage. Below I will list crane's functions. RC: 1,2) Chassis drive and steering - one L motor for each track. 3) Superstructure rotation 4) Operator's cabin uplifting via small linear actuator 5) Main boom winch 6) Luffing Jib winch - winch is located on the main boom like in the original model 7) First hook winch 8) Second hook winch - winch is located on the main boom like in the original model Manual: 1) Derrick boom winch - needs only when assembling/disassembling crane 2) Addiction counterweight extensioin - need to balance crane under heavy loads 3) Addiction counterweight up/low - need to balance crane under heavy loads or without a load 4) Addiction counterweight steering - need to steer wheels in the counterweight carriage when superstructure rotating and need to make wheels parallel to move crane forward or backward 5) Chassis uplifting - chassis have installed four small linear actuators which can lift the chassis under the ground to put on tracks like in the real Liebherr!! As TLG doesn't have any pulleys of 0.5 stud wide and with the pin hole in the center and 3D parts are too expensive I decided to drill the original ones. Firstly I used 4 mm drill to make a round hole instead of an axle, after 4,5 mm and finished with the 5 mm drill. No any part was broke. And this time I already has video to show you: And a couple of photos. https://bricksafe.com/pages/Aleh/liebherr_lr_11000 Hope you will like it. Feel free to ask any questions. Also very appreciate critics. But for sure my wife definitely will not stand another crane To start building i was inspired by the set 42042 - I love it too moch!
