Product Description Product DescriptionFront 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 Product ParametersItemUnitValueNominal tensionKN257Nominal oil pressureMPA50Tension piston areaM25.137*10Return piston areaM21.335*10Piercing hole diameterMM19Trolley tripMM200DimensionsMM180*568Return oil pressureMPALess than or equal to 25Product structurewidely 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 efficiency4, this type of jack to prevent the rotation of the steel strand, to avoid the elongation of the steel strand is too large. ApplicationsThe front clamp jack is mainly used in the field of prestressed engineering.In bridge construction, it is used for the construction of prestressed beam bodies of all kinds of Bridges, such as prestressed concrete box beams, T beams, etc. When the steel strand is stretched, the front clamp jack can accurately apply prestress, enhance the bending and cracking resistance of the beam body, and ensure the safety of the bridge structure when bearing loads such as vehicles.In construction engineering, it is suitable for the production of prefabricated components. For example, prestressed tensioning of prefabricated floor slabs, prefabricated piles and other components can improve the bearing capacity and durability of components and reduce the deformation of components during use. At the same time, it is also used for the prestressing construction of the main structure of the building, such as the application of prestress in the long-span concrete structure to ensure the stability of the structure.In geotechnical anchoring, the front clamp jack is used to stretch the anchor cable. In the engineering of slope reinforcement and deep foundation pit support, the unstable rock and soil body is connected with the stable stratum by applying prestress to the anchor cable, which can effectively prevent the sliding and collapse of the rock and soil body and ensure the safety of the project.
