After my fork rake and the tractor I present you the
AROCS SCV:pRC - Specialized Construction Vehicle: partially Remote Controlled
Today I would like to present my modification of the Lego 42043 MB AROCS to you. Yes, the setup is unusual for a typical construction truck. I decided to choose this setup because I like the crane setup from the old 8868 truck. The room between the specialized setup, which is inspired by the 8868 crane cabin, got filled with a side tipping bed. I moved the original tipping bed to the trailer. But first, let me tell you what functions it has inside and which of them can be controlled by RC.
1) RC package, supplied by one AA battery box:
Driving (XL-Motor, RC)
Steering (Servo, RC)
Supporting stand (L-Motor, 2 small linear actuators RC)
Tipping (L-Motor, 1 big linear actuator for each tipping bed, RC, switching between the two tipping beds possible through gearbox)
The RC functions are limited to functions needed while driving the truck or getting ready for working with the clamshell.
Because of the heavy weight of this model and the strong XL-Motor I had to replace the cv-joint with a cardan joint.
2) Clamshell package, supplied by one AA battery box:
Compressor (shares the M-Motor with the rotation)
Rotation (shares the M-Motor with the compressor)
The rotation of the clamshell setup can be changed or stopped through the red lever, which you can see on the right side, slightly under the cabin. If you switch on the battery box the M-Motor will run permanently and so will the compressor do. Only the rotation can be turned off through the gearbox.
All functions of the clamshell setup are integrated, so there is no cable or tube running through the turntable to the truck. There is no limited turning radius.
