Hydraulic bottle jacks also called hand jacks, provide an easy way to lift up a vehicle for service. Available in different sizes and weights, they have a lifting capacity of several tons. A hydraulic bottle jack is a robust and safe to use device with sturdy steel construction and a safety overload valve.

Hydraulic jack creates pressure by moving oil through two cylinders via a pump plunger. The pump plunger is drawn back, which opens the suction valve and draws oil into the pump chamber. As the plunger is pushed down, the oil is transported through an external discharge valve and into the cylinder chamber. The suction valve then closes, resulting in pressure being built up within the chamber; causing the piston in the chamber to rise and lift your heavy object. This process can be repeated many times, allowing your load to be lifted higher, and higher.
