SYSTEM / Hydraulic System
T2-3-1
OUTLINE
Hydraulic system is broadly be divided into the main
circuit, pilot circuit, steering circuit and hydraulic drive
fan circuit.
•
Main Circuit
Main circuit consists of the priority valve circuit,
neutral circuit, single operation circuit and
combined operation circuit – composed of the
main pump, priority valve, control valve, cylinders,
etc.
•
Pilot Circuit
Pilot circuit consists of the charging block circuit,
front attachment operation circuit, pump control
circuit, brake circuit and ride control circuit
(optional) – composed of the pilot pump, charging
block and valves to control each circuit.
•
Steering Circuit
Steering circuit consists of the normal steering
circuit, steering shockless circuit, emergency
steering circuit (optional), steering stop circuit –
composed of the pump, priority valve, steering
valve, cylinders and other valves.
•
Hydraulic Drive Fan Circuit
Hydraulic drive fan circuit consists of the flow
control circuit and reverse rotation control circuit –
composed of the hydraulic fan motor and the fan
pump.
NOTE: Steering circuit can be divided into the main
circuit and the pilot circuit. It is described
here as an independent circuit.
