When lifting the jack synchronously, the hydraulic pump first pressurizes the hydraulic oil to the hydraulic cylinder of the jack. Inside the hydraulic cylinder, with the injection of hydraulic oil, the pressure gradually increases, pushing the piston upward movement. The piston is connected to the ejector rod, so the ejector rod also rises, lifting the weight. The synchronous lifting function relies on advanced monitoring and control systems. Sensors are installed at key locations in each jack, continuously collecting data such as travel, speed, pressure and so on. This data is transmitted to the central control system and is quickly analyzed and processed. If it is found that the lifting progress of a jack is inconsistent with other jacks, the control system will change the working state of the jack by adjusting the flow direction and flow rate of the hydraulic oil, so that it can re-reach the synchronization state with other jacks. This ensures a smooth and coordinated process when lifting large steel structures or other heavy objects.

Preparation: First step, the top, middle and lower three automatic tool anchors of the jack are all in a relaxed jacking state (controlled by the auxiliary pump, and the automatic tool anchor controls the oil cylinder to jack up the anchor disc). (Some jack pistons extend out about 100mm, which is conducive to removing the pre-tightening jack or temporary wrong after pre-adjustment.) In the second step, the anchor of the fixed end tool is lifted with a pad, and the distance between the anchor and the lower cover plate is about 300mm, and the anchor is loose. The third step, threading through the upper, middle and lower three automatic tools wrong, check each hole instrument is correct, put the steel wire into the guide tube. Process: First, put the steel line into the guide tube, push it into the jack, and a person above the wrong part of the automatic tool gently holds the lead of the guide tube and moves with the thrust of the steel line.
Second, when the steel line comes out from the lower part of the cylinder, remove the guide pipe lead, lower the steel line until the speed slows down when approaching the anchor of the lower automatic tool, and pass through the wrong automatic tool at the alignment hole.
Third, when the steel line is 4-5 meters away from the anchor of the fixed end tool, the insert clip should be tightened at any time. If the steel line needs to be lowered, the clip should be lifted up and then locked until the steel line passes through the anchor hole where the fixed end tool should enter the clip, and the steel wire head enters the central plate hole for positioning. The upper personnel will loosen the steel grain line, that is, the steel lifting strand will be tightened on the automatic tool anchor clip. Fourth, lifting the upper steel lines beyond the automatic tool anchor 500mm, through the steel strand, the top of the jack 5 people, division of labor :1 person responsible for communication, 1 person responsible for placing pieces, hole position, other people responsible for paying off: the lower jack 2 people responsible for checking the automatic tool anchor and hole position, and finally connect the guide pipe lead; 3 people at the anchor of the lower fixed tool, and the work of wearing the clip, observing the lowering of the steel strand, and finally tightening. Fifth, when threading the strand, there should be good communication up and down, and the threading order should be stipulated in advance. Generally, the threading order can be used first inside and out, clockwise or counterclockwise, and the threading order can also be selected according to the row and column. When threading, the axis of the fixed tool anchor should be the same as that of the jack, and the line should be threaded after setting the order. When the automatic tool is incorrectly placed under the steel thread, it should be noted that the direction of the placing should be a certain distance from the worn steel strand to prevent twisting. Sixth, after the steel line of a jack is worn according to the above method, the anchor of the fixing tool is lifted close to the dislocation clamping clip, the press plate is set, the fixed bolt is inserted, and the next pre-tightening can be carried out after inspection.
