AI Technical Summary
Technical Problem
Conventional post-tensioning jacks are heavy, prone to slippage, and present pinch hazards during operation, leading to inefficiencies and safety concerns.
Method used
A lightweight dual-action post-tensioning jack with a dual-handle chuck and hydraulic pistons, capable of providing 7000-8000 psi pressure, featuring a sliding handle to ensure frictional engagement with the tendon and a gap to prevent pinching, along with a removable pressure cylinder for wear resistance and versatility.
Benefits of technology
The jack achieves efficient tendon tensioning with reduced weight, minimizes slippage, and eliminates pinch hazards, providing real-time pressure readings and significant weight savings compared to conventional designs.

Abstract
Exemplary embodiments may include a lightweight post-tensioning jack that also maintains a gap in a resting position to avoid potential pinch hazards. The lightweight post-tensioning jack may have dual -handles. It may also include a tendon chuck that is capable of providing enough friction between the chuck and tendon to avoid slippage and tensioning inefficiencies. The chuck assembly may be moved using a slidable handle; that is, one of the dual handles may be fixed and the other may be slidable to move the chuck.
