Car Jack Gear Set

The rack jack is composed of racks, gears, handles, etc. There is a rotating head above the load rack to place the lifted load. When in use, as long as the handle is shaken, the teeth will drive the rack to rise or fall, thereby realizing the rise or fall of the heavy object. Sometimes the load to be lifted can also be placed on the side lugs, but in this case the allowable lifting capacity of the rack is only half of the rated lifting capacity due to the eccentric loading of the rack. In order to support the load it lifts and prevent it from falling due to its own weight, it should be equipped with a safety handle device.
