Product Description

Product Description

The Concrete Beams Prestressing Mono Stressing Hydraulic Jack is a high-quality and professional tool designed for wholesale applications. With a tonnage range of 65-600 tons, this Hydraulic Stressing Jack is perfect for heavy-duty tasks. It is specifically designed for bridge hollow steel strand tensioning operations. The main part of the jack is constructed using high-strength steel, providing it with a compact structure, lightweight design, small size, and outstanding characteristics. Additionally, the jack has a short axial length, allowing for efficient steel wire tensioning in shorter lengths, resulting in significant steel material savings. The Hydraulic stressing jack is known for its lifting and flexibility, durability, easy operation, and convenient maintenance. It is specifically designed for tensioning steel hinge lines of prestressed reinforcement in various applications, such as Hydraulic Stressing Jack and tensioning operations in steel strand anchorage. For optimal performance, it is recommended to use this jack in conjunction with a high-pressure oil pump, which provides the necessary tension and power. The Hydraulic stressing jack finds extensive application in large buildings, post-tensioned structures, prestressed concrete bridges, rock anchoring, hydraulic structures, ground anchors, and other major projects. With its professional and reliable features, this Hydraulic Stressing Jack is an indispensable tool for various construction projects.

Precautions for operating hydraulic stressing jack:
Should first understand the engineering design of prestressed beam tension, such as root number, each beam of steel strand standard strength, the cross-sectional area of the numerical control stress of delta K, the value of stretching, anchorage retraction value, then according to the pressure of output power calibration of hydraulic. Set the K value of 2. 8, post tensioning hydraulic jack: (see Figure 2: installation method and hydraulic system diagram)
(1) the reserved corridor into the structure of the steel wire, in tension requirements of steel beam exposed length than the work length of jack up 200 - 250mm. steel wire must not loose head with a sheet grinder after cutting, is not a "feather", in order to avoid perforation difficult.
(2) cover the end of the steel wire of the work anchor plate, push it to the anchor plate and fix it at the end of the anchor
(3) installation: installation of anchor clamp clip before the steel ring pay per clip hoop together, and then along the strand will be pushed into the anchor hole, pushed by hand to move.
(4) installing the limiting plate: the spacing plate matches the hole of the anchor plate according to the design of the work anchor plate
(5) post tensioning jacks: first strand bundle end with wire pin and binding can be lifted, Jack is sheathed on the steel beam, Prestressed  Post Tension Jack and the front end cover is sheathed on the outside of the jack supporting limit plate. Then Jack can be coaxial pair.
Fit the tool anchor at the supporting end of the piston end.
