The rack jack is composed of rack, gear, handle and other components. The rack is used as a jack for rigid lifting. There is a rotating head above the rack to place the lifted load.
When the rack jack is used, as long as the handle is shaken, the teeth will drive the rack to rise or fall, so that the weight can rise or fall. Sometimes the lifted load can also be placed on the lug on the side, but in this case, special attention should be paid to that the allowable lifting capacity of the rack is only half of the rated lifting capacity because the rack is subject to eccentric load. In order to support the load it lifted and prevent the fall due to its own weight, a safety crank device shall be installed.
