Wholesale Low Profile & Double Pumps Hydraulic Garage Car Jack

When the high-pressure rubber hose leaves the factory, it has passed the withstand voltage test of 1.25 times of the rated pressure. Due to the aging of colloid, users should pay attention to regular inspection, once every six months, when using it for a long time. In case of leakage, bulge or explosion during pressure test, it must be replaced. When using, avoid discounts and sharp turns, and do not get too close to the rubber hose to prevent explosion. Steel pipe can be used for fixing. All parts shall be cleaned with kerosene. Pay attention to protecting all mating surfaces of the jack, and do not bump at will. After assembly, all moving parts shall move flexibly without local jamming.

The common hydraulic jack uses this principle to achieve force transmission. The screw jack pulls the handle in a reciprocating manner. Pulling the pawl pushes the ratchet clearance to rotate. The small bevel gear drives the large bevel gear to rotate the lifting screw, so that the lifting sleeve can be lifted or lowered to achieve the function of lifting tension, but it is not as simple as the hydraulic jack.
