Double Acting Power Unit

This double-acting hydraulic power pack has a power-up / power-down circuit (as opposed to single-acting or "gravity down" systems, where the weight of the attachment is enough to push the actuator down). Widely used in tipper trailers, fork lifts, scissor lifts, or any device where the ability to apply hydraulic fluid pressure to both working ports of a cylinder is necessary. Equipped with a high pressure gear pump, a DC motor, a multi-functional manifold, valves, and tank. Start the motor to raise and lower the actuator with the cable-mounted controller. There are unlimited uses for this product!
