Ultimate 42009

 

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
