Ultimate 42009 RC Mobile Crane Mk II
Just as I did with the 8043 Motorized Excavator, I made a fully remote controlled and improved version of the 42009 Mobile Crane Mk II set.
All the essential functions of the crane were motorized, which are:
- Driving (1x XL-motor)
- Steering (1x M-motor)
- Outriggers (1x M-motor)
- Outrigger-legs (1x M-motor)
- Lifting/lowering boom (1x L-motor)
- Extending/retracting boom (1x L-motor)
- Lifting/lowering hook (1x M-motor)
- Upperstructure 360+ degree rotation (1x M-motor)
Funtions that were improved:
- Boom extends further. Max boom-length 96 studs
- Boom retractrs further
- Better steering-lock
- Solid metal hook
- Increased lifting power
- Faster outriggers
- More efficient drivetrains
Full building instructions are available as free download. And there are 2 different parts-lists: 1 for the complete model and 1 that only contains the extra parts needed bedises a standard 42009. Go to the Instructions page to download them
