The operation principle of the front clamp jack is the synergistic effect of hydraulic drive and mechanical clamping. The hydraulic pump drives hydraulic oil into the cylinder, and the oil pressure acts on the piston, prompting it to move forward along the cylinder. At this point, the clamping plate at the front of the steel strand is tightly jammed, and as the piston moves forward, the steel strand is stretched, thus creating prestress. In this process, the sealing device of the jack ensures that the hydraulic oil does not leak out and ensures the stable transmission of pressure. When the prestress reaches the specified value, the jack maintains the pressure for a period of time to stabilize the prestress effect. Finally, the oil return operation makes the piston withdraw under reverse pressure, and the clamp releases the steel strand, and its precise control ability makes the prestressing construction in Bridges, buildings and other projects complete with high quality.

The front clamp jack mainly has the following structural characteristics:
Compact front end structure
- The front end of the front clamp jack is its key part, and the clamping device is compact. The clip can accurately jam the steel strand and effectively transfer the tension during the working process, and its compactness makes the jack can operate well in a small space, such as in the internal prestressing construction of the bridge box beam, it can easily stretch the steel strand.
Hydraulic system
- With hydraulic drive as the core, including components such as cylinder, piston and hydraulic oil path. The seal of the cylinder is good, which can effectively prevent the leakage of hydraulic oil, ensure that the piston can be stably extended forward under the push of oil pressure, and successfully retracted when the oil is returned. This hydraulic system enables the jack to output a large pulling force, which is enough to meet the requirements of applying a large prestressing force to the steel strand in the prestressing construction.
High strength cylinder block
The cylinder block is an important support part of the entire jack and is usually made of high-strength metal materials, such as high-quality alloy steel. This allows the cylinder to withstand high hydraulic pressure without deformation, providing stable guidance and support for the movement of the piston, and ensuring the accuracy and reliability of the jack during the working process.
Easy to connect parts
- Easy to connect with oil pump, tubing and other equipment interface. Through these interfaces, it can be easily connected with the external hydraulic system, so that the hydraulic oil can smoothly enter and exit the jack, and the connection mode is relatively firm, which can prevent the oil pipe from falling off during the working process.
