HYDRAULIC LIFT SYSTEM
PUMPS - Provide the hydraulic pressure to operate the hydraulic lift system. Operated by hand pump (or from remote air
source through an air motor mounted on the pump assembly).
PUMP RELEASE VALVE - Places the pump in an operating position (PUMP) or releases the pump pressure (REL)
depending on its position.
CYLINDERS - Provide the system lifting power. They are independently actuated by hydraulic pressure, each from a
dedicated hydraulic pump. The dolly set has four hydraulic cylinders.
MANUAL BLEEDER VALVES - Allow each hydraulic cylinder to be independently bled as desired.
AIR MOTORS - Provide pneumatic power (when attached to external source of air power (70 to 120 psi)) for automatic
operation of hydraulic pumps.
