Advantages of using hydraulic wrench: the output torque is large, compared with wind cannons, torque wrenches, traditional wrenches, the output torque of hydraulic wrenches is several times or even hundreds of times, up to hundreds of thousands of torque, which can meet the pre-tightening and loosening of most specifications of bolts on the market; Torque accuracy is guaranteed, some industries have requirements for torque accuracy, must use hydraulic wrenches, such as wind turbine hoisting, to ensure that the force of a circle of bolts is consistent, that is, the torque of each bolt is required to be consistent, otherwise there will be collapse, only hydraulic wrenches can be guaranteed; Can replace manual work, with the increase of labor costs, now a hydraulic wrench can replace the amount of work before several people; The safety of on-site use is guaranteed, many factories before bolts, either use a sledgehammer, or use a crane, or use a forklift, which bring great risks to safety; To meet the narrow space conditions, for many bolts with limited space, other wrenches can not be put in, hydraulic wrenches can be competent, saving labor while improving efficiency and ensuring torque.
Classification of hydraulic wrench: Hydraulic wrench is divided into drive hydraulic wrench and hollow hydraulic wrench according to the use, which is used for different bolt conditions. The drive hydraulic wrench is used with the standard sleeve. It is a universal hydraulic wrench with a wide range of application. Hollow hydraulic wrench directly acts on the nut, for different specifications of bolts, replace the reducer sleeve or working head can be its thickness is thinner, more suitable for the space is relatively narrow place to use.
