31" Stroke Jack with overload w/ relief valve On Star Hydraulics, LLC

In a single, compact lightweight unit, Star has combined an efficient pump and durable cylinder that produces one ton lifting capacity. The model HF500 Jack is easy to operate-takes only 4 1/2 pounds of pedal force per 100 pounds of load, and it is fast acting. For each stroke of the folding pump foot pedal, the cylinder piston rod moves 1/2 inch. The unit has a built-in release pedal for rapid lowering, and the Jack is equipped with lugs that make it easy to mount. Star will provide any cylinder stroke length subject to the limitations shown in the specification table below.
