Jack

A jack is a light lifting device that uses a rigid lifting member as a working device to open a heavy object through a small stroke of a top bracket or a bottom bracket. Jacks are mainly used in factories, mines, transportation and other departments for vehicle repair and other lifting and support work. The structure is light, sturdy, flexible and reliable, and can be carried and operated by one person.
(1) The basis of the jack. The foundation of the jack should be stable, solid and reliable. When jacks are placed on the underside, roads or other suitable materials should be placed to enlarge the area of ​​force.
(2) Placement of the jack. When placing a jack on a soft ground, the wooden block should be placed under the jack to avoid tilting and tilting. When the weight is raised, the weight should be placed under the support pad at any time, but the hand cannot be mistaken into the danger zone.
During the placement process of the jack, the line of action of the center of gravity of the load is kept consistent with the axis of the jack. During the jacking process, the risk of pinching and tilting of the jack due to the deflection of the foundation of the jack or the horizontal displacement of the load should be strictly prevented. It is necessary to prevent the jack from slipping in contact with the metal surface of the heavy object or the smooth surface of the concrete, and if necessary, the hardwood block is used.
(3) Lifting operation. The top elevation of the jack should not exceed the effective top. When lifting large objects (such as girders), they should be separated and raised at both ends, and one end should be lifted and lowered, and the other end must be solid, padded, and stabilized. The jack is not allowed to be overloaded.
It is not advisable to start the jacks in a hurry. The rhythm should rise at a constant rate and slow down when falling. When multiple jacks are used at the same time, they must be operated synchronously. After the jack is completed, it is necessary to carry out a serious inspection, check the oil pressure and hidden dangers, carry out maintenance and place it in an appropriate place.
