A hydraulic wrench is generally composed of a hydraulic torque wrench body, a hydraulic torque wrench dedicated station, and a high-strength heavy-duty socket with dual high-pressure hoses. The hydraulic wrench dedicated pump has two driving modes, one is electric driving mode and the other is pneumatic driving mode. After starting the hydraulic wrench hydraulic pump, there is oil pipe medium in the hydraulic torque wrench, and the pressure generated by external objects can be transmitted through the medium to drive the hydraulic torque wrench's oil rod to rotate the drive shaft to complete the pre tightening and loosening work of the bolt.

Many personnel tighten and remove bolts because hydraulic wrenches can help workers solve this heavy workload, so they are often used to deal with bolts. This not only improves work efficiency, but also helps reduce people's labor and greatly improves the quality of installation.

Hydraulic wrenches are mainly used in industries such as heavy metals and heavy machinery, providing a large amount of torque output. They use hydraulic power and are used for installing and disassembling professional bolt tools, as well as tightening and loosening extremely large bolts. A hydraulic wrench is mainly composed of three parts, namely a frame, an oil cylinder, and a rotating component.

The demand for hydraulic wrenches in China today is very high, and they are needed in various industries such as construction, petrochemicals, metallurgy, mining, power, and shipbuilding. They have become an irreplaceable tool in installation and disassembly work. The torque provided by hydraulic wrenches is enormous and the data is very accurate, and using hydraulic wrenches is both convenient and lightweight.

According to testing, the repeatability accuracy of hydraulic wrenches is less than 5%. According to relevant statistical analysis, about 50% of equipment failures are caused by bolt problems. Therefore, the torque requirements related to the tightening and dismantling of bolts are very strict during the installation and repair process of the equipment.

In summary, hydraulic wrenches play an important role in many fields and cannot be replaced by anyone else.
