HYDRAULIC SYSTEM
GENERAL
The hydraulic system supplies the hydraulic pressure needed for the operation of the hydraulic components on the vehicle.
It consists of a hydraulic pump and oil reservoir, three winches, operator's console, four outriggers, a derrick, auger, and
lines.
HYDRAULIC PUMP
The hydraulic pump is a double action-vane type pump with internal flow control and pressure relief valves and is driven by
a power takeoff on the transmission. It is mounted to the frame and supplies fluid pressure to the control valves to operate
the hydraulic components. The oil reservoir is mounted in the right side of the body.
WINCHES
The three winches are hydraulically powered and are mounted on the front bumper platform, inside the body and in the
turret. They are powered by hydraulic motors that transfer fluid pressure to mechanical power.
OPERATOR'S CONSOLE
The operator's console is an operator's station consisting of a cabinet and control valves mounted on the rear of the body.
The valves open the flow of hydraulic oil from the pump to the hydraulic components for operation.
