How to Choose Bolt Stretcher

To choose bolt stretcher depends on the stretching mode first, the required pretightening force Kn, and then the torque mode, and the required tightening torque Nm. Bolt stretching is to use hydraulic cylinder to exert external force on the bolt end, stretch the bolt to the required length, and then tighten the nut, so that [...]

Characteristics of Hydraulic Wrench’s Coarse and Fine Tooth

The hydraulic wrench's coarse and fine tooth is divided by the ratchet and pawl. The single teeth engaged by the ratchet and pawl are called coarse teeth, and the multi teeth engaged are called fine teeth. The two structures have their own advantages and disadvantages. We carefully understand hydraulic wrench's coarse and fine tooth advantages [...]

Disassembling the Hydraulic Cylinder

Before disassembling the hydraulic cylinder, the hydraulic circuit should be depressurized, otherwise, when the oil pipe joint connected with the cylinder is loosened, the high-pressure oil in the circuit will be ejected rapidly. When the hydraulic circuit is depressurized, first loosen the hand wheel or high-pressure screw at the overflow valve to unload the pressure [...]
