Front clamp jack operation relies on hydraulic drive and unique clamping structure. After starting, hydraulic oil is pressed into the cylinder to push the piston forward. The clip holds the steel strand firmly in advance, and with the displacement of the piston, the steel strand is stretched and the prestress is generated. The jack has a sensitive pressure feedback system, which can accurately control the tension process according to the preset value, and maintain the pressure holding state after achieving the target prestress to ensure the effectiveness of prestress. After the completion of the tensioning operation, the oil return makes the piston reset, and the clip releases the steel strand. The scientific and reliability of the principle makes it indispensable in the prestressed projects such as Bridges and buildings, and effectively guarantees the quality and safety of the engineering structure

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.
1. The jack adopts the front clamp type, that is, the tool anchor is in front, which can save the prestressed reinforcement material.
2, equipped with a number of different gaskets, the work can be selected according to the specifications and tension of the clip,
3, in the tensioning process, the jack can realize the automatic clamping of prestressed tendons and anchor withdrawal, thereby reducing labor intensity and improving efficiency
4, this type of jack to prevent the rotation of the steel strand, to avoid the elongation of the steel strand is too large.
