A Single-Acting Hydraulic Jack is a type of hydraulic jack where hydraulic pressure is applied in only one direction (lifting). The return stroke occurs automatically either by load (gravity) or by an internal spring.
A Single Acting Load Return Hydraulic Jack is a type of hydraulic jack where hydraulic pressure is applied in only one direction (lifting) and the return stroke happens automatically due to the load’s weight (gravity).
Hydraulic oil is pumped into the cylinder → piston extends → load is lifted
Hydraulic pressure is released → load weight pushes the piston back → oil returns to tank
A Single Acting Hydraulic Jack (Spring Return Type) is a hydraulic lifting device where hydraulic pressure is applied only for lifting, and the return (retraction) is done automatically by an internal spring when pressure is released.
