Hydraulic jacks, hydraulic jacks, the former cassette jack, feedthrough jack, hand-held pneumatic drills to help anchor, anchor cable tensioning equipment, manual pump, the first cassette feedthrough jack, hydraulic force gauge 
 Special hydraulic jacks special tensioning equipment used in the production of prestressed concrete members, the tension applied to the prestressed reinforcement. Dedicated mostly double-acting hydraulic jack type. Feedthrough and used before the card has two. 
 Feedthrough jack for tensioning steel beam or steel beam, which is mainly from the tension cylinders, pressure tank top, top compression piston and spring components. It is characterized by: one axis along the tensile machine mandrel channel, steel (or wire) by the end of the tool after penetration anchor anchor 
 Jack is a multi-purpose cassette before the prestressing device, easy to operate. Mainly for single-hole tension. Can be used for porous preload, tension, and troubleshooting and can be applied to a variety of specifications and dimensions of high-strength steel wire strand bundle. 
 Feedthrough jack, the main anchor for the group overall tension. The jack is simple, reliable performance, and maximum savings strand. Jack and the main anchor with prestressed tension equipment and other products used in bridge construction and other projects.
