Tensioning equipment

Tensioning equipment is a special equipment for tensioning prestressed bolt and building prestress. It mainly consists of a jack and high pressure oil pump, and sometimes includes a pressure sensor for measuring tension and a dial gauge for measuring anchor head displacement. The tension acting on the prestressed bar of the bolt needs to be measured by an instrument during tensioning. There are several different types of prestressed tension jacks: through jack, push jack, front clamp jack; Among them, the through-core jack is generally used for the overall tension of the group anchor, which is simple in usage and reliable in performance. It can also save the steel strand if used well. It is generally used for the large-span structure and long steel strand and other large elongation projects. And the role of push-type jack and through-type jack is still some difference, the main role of through-type jack is tension, and the role of push-type jack is pushing, lifting and displacement, generally used in Bridges, high-rise buildings and other places. Finally, the front clamp jack, as a multi-purpose prestressed tension equipment, the operation is also very convenient, mainly suitable for single hole tension, can also be used for porous pretension, tension and barrier, can be applied to a variety of sizes of steel strand.
