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
