Description
The Concentric AC hydraulic power unit is specifically designed
for auto hoist applications. However, it may be used for other
intermittent duty applications that utilize the power up - hold -
gravity lower hydraulic circuit. This hydraulic unit must be used
for mounting in a vertical position (motor up/reservoir down) and
is typically mounted on the side of the auto hoist frame. It is pre-
wired with a push button start switch. Additional features include
a load holding check valve, a manual lowering valve with “feather-
ing” capabilities and a 3 gallon capacity reservoir. The adjustable
relief valve is preset at 2200 PSI.
THIS HYDRAULIC UNIT IS SPECIFICALLY DESIGNED FOR
INTERMITTENT DUTY APPLICATIONS. ANY ATTEMPT TO RUN THE
UNIT FOR EXTENDED PERIODS OF TIME MAY CAUSE DAMAGE TO
THE 115/208-230 VAC ELECTRIC MOTOR.
