To make it more interesting I decided to use its parts and make an MOC loosely based on the Liebherr LTM 1200 5.1.
And this is what I came out with.
All functions are comparable to bigger scale models like e.g., the 8460.
- Four outriggers stabilize the crane while lifting- A rotating crane, mounted on the new turntable elements (99010, 99009)
- The crane is lifted pneumatically with a Pneumatic Cylinder (47224c01)
- The crane consists of two booms so it can extend
- A hook with rope
- Dummy engine
The most difficult part was the steering system and it took several attempts to realize it. I got inspired by the LEGO® Technic 9390 and developed the idea. This result in a modular system of small size. The turning radius is nearly 40 cm.
Note: None of the axles are meeting in a pivot point which causes some problems (slipping wheels, vibrations), especially on the front axle. I made this compromise according to the small scale.
More detailed pictures of the steering mechanism to be found on Brickshelf.
The Boom is lifted by a Pneumatic Cylinder (47224c01). Two Small Pumps (x191c01) provide the air and I used a Technic, Shock Absorber 6.5L, Complete Assembly (Normal Spring) (731c05) to run the pumps manually. With an 1L stroke you have to push about 20 times to lift the heavy boom.
The boom is extendable and uses Erik Leppen's design. It's really strong and fits the scale quite well.
I'm very happy how everything turned out and I hope you like it as well.

LEGO® Digital Designer lacks in some parts, you have to replace the fake parts of these:- Pneumatic Cylinder (47224c01)
- Two Small Pumps (x191c01)
- Pneumatic Switch (4694b)
