The principle of the front clamp jack is based on hydraulic transmission and mechanical locking mechanism. The hydraulic oil enters the cylinder under pressure and pushes the piston forward. The clamping mechanism has locked the steel strand at the beginning, and with the movement of the piston, the steel strand is stretched and the prestress is gradually formed. During tension, the tension force can be accurately set and monitored by the automatic control system, and the pressure can be maintained after reaching the target value, so that the prestress can be stabilized. After the job is completed, the oil is returned to allow the piston to return, and the clamp unlocks the strand. This principle ensures that in all kinds of prestressed projects, such as the prestressed roof truss construction of industrial plants, the prestressed stress can be applied efficiently and accurately, and the stability and durability of the structure can be enhanced.

jack is used in highway bridge, railway bridge, hydropower dam, high-rise building and other prestressed construction projects. Whether the tensile force value of the prestressed tensioning jack device is accurate or not will directly affect the project quality and safety production. Therefore, it is very important to calibrate it and provide accurate and reliable test data. YQC27T and VQC25T type jack is a kind of prestressed core through the front clamp jack, compared with the existing jacks, with the function of preventing the rotation of the steel strand, used in M15, M13 with and without bonding tendons single tensioning, widely used in pre-tensioning, post-tensioning prestressed concrete structure, bridge, rock and soil anchorage and other major projects. Especially suitable for high-altitude operation, easy to carry.
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.
