During the placement of the jack, the action line of the load center of gravity should be consistent with the axis of the jack. During the jacking, the risk of the jack being tilted or tilted due to the deviation of the jack foundation or the horizontal displacement of the load should be strictly prevented. To prevent the jack from sliding on contact with the metal or concrete surface of the weight, a hardwood block is used if necessary.
