Main Classification And Characteristics Of Hydraulic Wrenches

There are two series of hydraulic wrenches: driven hydraulic wrench and hollow hydraulic wrench. As the name suggests, the drive hydraulic wrench relies on the drive shaft to drive the corresponding specification sleeve to achieve the pre-tightening of the nut. As long as the torque range allows, the bolts of different specifications can be replaced by the corresponding high-strength sleeve. , The scope of application is wider.

The hollow hydraulic wrench is equipped with a transition sleeve. Generally, the extension of the screw rod is relatively long, the space range is relatively small, the distance between double nuts and bolts is too small, the nut and the equipment wall are too small, or there are more difficult working conditions in some specific industries.

Hydraulic wrenches are widely used; in shipbuilding, petrochemical, wind power, hydropower, thermal power, mining, machinery, steel mills, rubber, pipelines and other industries construction, maintenance, emergency repairs, etc., hydraulic wrenches are used for large-size bolts. Installation and disassembly are a relatively important tool; there are other tools irreplaceable, not only easy to use, and the torque provided is very accurate, the torque repeatability is about ±3%.
