Hydraulic jack for lifting bridge is often used in the replacement of bridge bearings. Here, Zhengzhou Lead Equipment Co., Ltd. will explain the bridge construction project and configuration for you. Lifting hydraulic jacks for bridge are very complicated in 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. One electric pump station can provide power for 4 to 32 or more hydraulic jacks. Synchronous lifting realizes the installation or replacement of the bridge support pad. Due to the increasingly busy traffic, the reinforcement of highway bridges and overpasses has been put on the agenda. By adding additional piers and evenly distributing the load of the bridge beams to the old piers. Can increase traffic flow. Use ultra-thin hydraulic jacks or self-locking hydraulic jacks to lift the bridge, replace the cushion, and finally put it back to the new pier position. It seems that hydraulics can do anything. When faced with this type of engineering problem, 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.
It is necessary to check whether all parts are normal before use, mainly to check whether the piston, joints, high-pressure hose, etc. leak oil. Strictly abide by the provisions in the main parameters when using it, and avoid super high and overload, otherwise, when the lifting height or lifting tonnage exceeds the regulations, serious oil leakage will occur at the top of the cylinder.
After the lifting hydraulic jack for bridge lifts up the heavy object, the support should be used to support the heavy object in time. When several jacks need to be lifted at the same time, the hydraulic jack for lifting bridges 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 being lifted from tilting and causing danger.
When using a lifting hydraulic jack for sale, place the oil cylinder in a good position, and tighten the oil drain screw on the oil pump to work. Even if the piston rod descends, loosen the hand wheel of the manual oil pump slightly in the counterclockwise direction, the oil cylinder is unloaded, and the piston rod gradually descends. Otherwise, the falling speed will be dangerous.
