Main feeding of the equipment is hydraulic, power by a diesel engine at which exits are installed the hydraulic pumps that send the oil to the different motors.
The choice of hydraulic translation is to guarantee a safe and proper distribution of the forces and speed during running and specially steering of the equipment.
Pumps have variable displacement so all controls can be fine tuned by handling properly the joy stick on the remote control.
Lifting is via winches controlled by hydraulic motors. Can work independently or coupled.
Also translation of lifting points is via hydraulic motors.
All controls are from closed cabin or wireless remote controller.
