The front clamping jack adopts the structural form of "static piston and moving cylinder body". When the prestress is applied, the jack piston and the tension weighing sleeve are stationary, the outer cylinder liner, the core sleeve and the tool anchor move backward relative to the jack piston, and the tool anchor and the tool clip clamp the steel strand for tension. After the required prestress value is reached, the oil is returned, the outer cylinder liner and the core sleeve are reset, and the working clip and the working anchor are automatically anchored to complete the tensioning process

The structure of the front clamp jack
The front clamp jack is a kind of tool specially used for the tensioning and anchoring construction of prestressed projects, and its structural design has unique advantages, which is suitable for a variety of scenarios such as single-hole tensioning, group anchor tensioning, troubleshooting, unanchoring, and additional tensioning. The following are the main structural features of the front clamp jack:
Structural characteristics
Double seal design: tension cylinder and return cylinder are double seal design, improve the reliability of the seal. The small cylinder and the second cylinder, the small cylinder and the rear end cover and the small cylinder and the tool ring are connected by keys to prevent rotation. The seal is made of Glay ring or Ster ring to ensure the sealing effect.
Integral two cylinder and piston head: The two cylinder and piston head are designed as one piece, avoiding the possibility of failure due to two body welding or two body threaded connection.
Improved wear resistance design: The wear ring and wear sleeve have been improved to avoid the possibility of assembly force out and improve the reliability of the product
