The core of the working principle of the front clamp jack is hydraulic transmission. The oil pump pressurizes the hydraulic oil and transmits it to the jack cylinder to push the piston forward. The clamping device pre-clamps the steel strand, and with the movement of the piston, the steel strand is stretched and the stress is gradually increased. After reaching the preset tension value, the pressure holding system of the jack starts to maintain a stable pressure and ensure the accurate application of prestress. After the completion of tension, the oil return valve opens, the hydraulic oil returns, the piston retracts under the action of spring or self-weight, and the clip releases the steel strand. The whole process realizes the accurate and efficient prestressed tension of the steel strand, providing stable and reliable prestressed support for the building structure.

peculiarity
1, Prestressing Mono jack is the prestressing tool anchor, which can save prestressing tendon materials.
2, Prestressing Mono jack is equipped with a number of different gaskets, which can be selected according to the specifications and tension of the clip when working,
3, in the process of tension, Prestressing Mono jack can achieve automatic clamping of prestressing tendons and anchorage, so as to reduce labor intensity and improve efficiency
4, Prestressing Mono jack working to prevent the rotation of the steel strand, to avoid the elongation of the steel strand is too large.
