42043 Alternate – Mobile Crane

Alternate model for 42043 Mercedes Arocs. Features 3 manual and 4 motorized functions. Instructions available at MOCPlans.com

My first try on making one set MOC. I decided to build a mobile
crane, because Arocs has great amount of universal parts, and it was
quite challenging to fit four functions into the supestructure with
given range of parts (for example – it uses almost all gears provided
with the set). It has three manual functions – steering (three axles are
steerable), supestructure rotation and fake V6 engine behind the cab.
Four motorized functions are powered by L motor trough two gearboxes.
First one allows to fold/retract stabilizers and fold/retract crane arm.
Second one operates winch and pneumatic pump. The winch can be locked
in place.

The model comes with full building instructions, that
are divided into submodels (like chassis, cab, deck parts,
supestructure, crane arm, etc.)

Please not that 42043 set DOES NOT comes with a string, so this model needs additional, at least 2m long string.
