Twistlock Hydraulic Accumulator
Mounted just to the rear of the chassis
articulation joint and is connected directly to the
hoist valve pilot pressure circuit. The
accumulator provides additional pressurized
hydraulic volume on demand for the body
twistlock manifold assembly for twistlock
operation.
Twistlock Solenoid Manifold
The hydraulic accumulator is a high pressure
charged vessel. Follow the CAT 735
Maintenance and Service Manuals for proper
charging procedures. Failure to charge this
vessel properly may result in serious personal
injury or death. Twistlock Solenoid Manifold
The manifold assembly is mounted to the body
assembly cross tube. The manifold receives
pressure from the accumulator assembly while
routing return pressure to the chassis hydraulic
tank. The manifold contains a solenoid valve to
route hydraulic pressure and return to and from
the twistlock actuators as commanded by the
twistlock controls and a pressure reducing valve
to prevent over pressurization of the twistlock
actuators.
