Pre stressing front-end fixed jack is a specialized equipment used for tensioning prestressed steel bars, especially widely used in engineering projects such as highway bridges, railway bridges, hydropower dams, and high-rise buildings. The design of this type of jack is mainly intended to be used in conjunction with a high-pressure oil pump, providing the power for tensioning and rebounding through high-pressure oil, ensuring the quality and safety of prestressed construction projects.
The main characteristics of the prestressed front-end fixed jack include:
The compact structure allows for effective use even in narrow spaces or high-altitude operations.
Easy to operate, able to adapt to various specifications and sizes of high-strength steel wire bundles and steel strands, meeting different engineering needs.
High efficiency, small size, light weight, especially suitable for use in work environments with limited space or frequent movement.
In addition, the prestressed front-end fixed jack also has the following technical characteristics:
The sealing reliability is high, and the use of double sealing technology improves the reliability of the seal and reduces the possibility of leakage.
The anti rotation device, through the installation of thrust bearings between the rotating sleeve and the through sleeve, as well as the clearance fit between the tool anchor ring and the through sleeve, achieves stable tensioning of the prestressed reinforcement and avoids its rotation.
This type of jack has a wide range of applications, not only for single hole tensioning, but also for multi hole pre tensioning, tensioning, and obstacle removal, demonstrating its versatile characteristics. Due to the use of new sealing components and precision manufacturing processes, the prestressed front-end fixed jack not only improves labor efficiency and reduces labor intensity, but also ensures the quality and safety of the project. In addition, due to its simple structure and easy operation, it has been widely applied and recognized in engineering practice
