LEGO Technic Multi-Function Off-Road Truck (MFORT) Attachment - Crane

I have recently completed my latest attachment for my LEGO Technic Multi-Function Off-Road Truck (MFORT), this is a crane attachment.

This features three features:
- The black knob on the side controls the turn table which makes the crane move.
- The yellow knob lifts and lowers the crane arm.
- The grey knob controls the raising and lowering of the rope and hook.
