A hydraulic power supply is disclosed. This power supply contains a reservoir, an electric motor, and a variable volume pressure compensated pump. The motor used in the device rotates at a speed which does not exceed 1,200 revolutions per minute and produces from about 3 to about 5 horsepower and a torque of from about 12 to about 30 foot pounds. The ratio of the torque to the horsepower (in foot-pounds per horsepower) does not exceed about 4.0. The hydraulic power supply includes an adaptor for connecting the electric motor and the pump and for suspending the electric motor and the pump away from at least one wall of the reservoir.
