Hydraulic jack for lifting bridge
The hydraulic jack for lifting bridge is usually used to replace the bridge bearing. We will explain the construction project and configuration of the bridge for you here. The lifting hydraulic jack of the bridge is very complicated in the bridge construction and the equipment is reliable. Sex directly affects the success or failure of the project.

Hydraulic jack for lifting bridge: the bridge construction project is very complicated, and the reliability of the equipment directly affects the success or failure of the project. The hydraulic system provides a reliable guarantee for the support, lifting and other applications of the bridge structure. In the bridge erection project. An electric pump station can provide power for 4 to 32 or more hydraulic jacks. Synchronous lifting realizes the installation or replacement of bridge support pads.
Due to increasingly busy traffic, the reinforcement of highway bridges and overpasses has been put on the agenda. By adding additional piers, the load of the bridge is evenly distributed to the old piers. Can increase traffic flow. Use ultra-thin hydraulic jacks or self-locking hydraulic jacks to lift the bridge, replace the cushions, and finally put it back to the new dock position. It seems that hydraulics can do anything. When faced with such engineering problems, system design becomes a key issue. Through our close cooperation with customers and the accumulation of our rich knowledge and experience in this field. Can make this kind of project a complete success.

Before use, you must check whether all parts are normal, mainly check whether the piston, joints, high-pressure hose, etc. leak oil. Strictly abide by the provisions of the main parameters when using it to avoid over-height and overload, otherwise, when the lifting height or lifting tonnage exceeds the prescribed, serious oil leakage will occur at the top of the cylinder.
After the lifting hydraulic jack of the bridge lifts the heavy object, the support should be used to support the heavy object in time. When it is necessary to lift multiple jacks at the same time, the hydraulic jacks of the suspension bridge should be placed correctly, and the load of each jack should be balanced, and the lifting speed should be kept synchronized to prevent the weight from tilting and tilting. Cause danger.

When using a lifting hydraulic jack sold on the market, please put the oil cylinder in the proper position, and then tighten the oil drain screw on the oil pump to work. Even if the piston rod descends, you can slightly loosen the hand wheel of the manual oil pump in a counterclockwise direction, unload the cylinder, and then the piston rod gradually descends. Otherwise, the descending speed will be dangerous.
