(1) Foundation of Jack. The foundation of Jack shall be stable, solid and reliable. When the jack is set at the bottom, the track wood or other appropriate materials shall be padded to expand the stress area.

(2) Placement of jacks. When placing a jack on a soft ground, a wooden block shall be placed under the jack to avoid tilting and tilting after being stressed. When the heavy object is lifted, the supporting skid shall be placed under the heavy object at any time, but the hand shall not enter the dangerous area by mistake. During the placement of the jack, keep the action line of the load center of gravity consistent with the jack axis. During the jacking process, strictly prevent the risk of Jack deflection and inclination due to the jack foundation deflection or load horizontal displacement. To prevent the jack from sliding in contact with the metal surface or smooth concrete surface of the weight, hardwood blocks shall be padded if necessary.

(3) Jacking operation. The jacking height of the jack shall not exceed the effective lifting distance. When lifting large objects (such as girders), both ends shall be lifted and lowered separately, one end shall be lifted and lowered, and the other end must be padded, firmly padded and placed stably. Do not overload the jack.

Jack refers to the light and small lifting equipment that uses the rigid lifting part as the working device to lift the heavy objects through the small stroke of the top bracket or the bottom claw. The jack is mainly used for vehicle repair and other lifting and supporting work in factories, mines, transportation and other departments. The structure is light, firm, flexible and reliable, and can be carried and operated by one person. It can be divided into mechanical jack and hydraulic jack, with different principles.
