Here is my latest MOC, a wheeled exvacator with PF and pneumatic. Compared with the technic wheeled exvacator MOCs I have seen by now, the TEREX TW110 has no seperate PF component on chassis and all PF components are implemented in superstructure. The driving propulsion and steering torque are transfered from superstructure to chassis like the exvacator in real life (same principle as what appears in 8043).
In this MOC, the main features of a compact wheeled exvacator (TEREX TW110) are realized.
The exvacator has four RC channels (two IRs) and two gear boxes:
Channel 1, driving propulsion (AWD) or pneumatic propulsion switched by No.1 gear box (manual), powered by a 5292 9V motor;
Channel 2, upper structure rotation or boom lateral adjustment (Knickmatik) switched by No.2 gear box (manual), powered by a PF M motor;
Channel 3, steering (AWS) with functional steering wheel, powered by a PF M motor;
Channel 4, LED head lights.
Other features includes:
Central differential in chassis;
Pneumatic dozer blade (manual);
Three air valves in cab, controlling three boom cylinders (manual);
Openable cab door;
Easy maintanance (eg. battery replacement).
