Key features of Hydraulic Stressing Jack:
Heat treatment to machine workable range. The heat treatment increases the hardness and durability of the material, lengthening its service life.
Welding the copper, which can be done in three ways :
oxy-acetylene welding of copper,
gas metal arc welding of copper (GMAW), and
CO2 welding. Our factory uses oxy-acetylene welding of copper, which is the most expensive method , but yields the best results.
Fine machining (boring, threading, lathe processes)
Filling up the holes, grinding
Electroplating the piston and inside of the cylinder (to increase the hardness of contact surfaces).
Verify the serial numbers, then assemble the various parts (including sealing rings)

Introduction of Hydraulic Stressing Jack:

Hydraulic Stressing Jack is mainly used for overall tensioning of group anchors. The jack is simple to operate, reliable, and saves strands. Jack mainly used with pre-stressed anchorage equipment and tensioning equipment and other products used in the construction of bridges and other projects.

Hydraulic Stressing Jack , the main anchor overall tension. The jack is simple to operate, reliable, and saves strands. Jack mainly used with pre-stressed anchorage equipment and tensioning equipment and other products used in the construction of bridges and other projects.

Hydraulic Stressing Jacks are double-acting jacks that utilize twin hydraulic cylinders to tension prestressed tendons and jacking anchors. Through-type jacks are suitable for tensioning belts

The working principle of hydraulic stressing Jack is as follows: When tensioning prestressed tendons, pull the cylinder oil nozzle into the oil, top pressure cylinder

Oil return, top pressure cylinder, connecting sleeve and support sleeve are integrated into one body and the anchor ring is moved to the right. Tension cylinder, end cap nut and plug head and feedthrough sleeve are integrated to drive the tool anchor to pull the prestressed tendons leftward. When pressing and anchoring, under the condition of maintaining the stability of tension, the top pressure cylinder oil nozzle enters the oil, the top pressure piston, the protective sleeve and the top pressure head are connected to the right to push the clamp piece into the anchor ring; Pull cylinder oil return, top pressure cylinder oil inlet, pull cylinder hydraulic return. Finally, the pulling cylinder and the top pressure cylinder oil nozzle simultaneously return oil, and the top pressure piston returns under the action of the spring force.
