Hydraulic wrench application
In many industries, such as metallurgy, petroleum, railway, mining, wind power, etc., hydraulic wrenches play a very important role. Each bolt in the coupling device has a fixed torque value for tightening and disassembling. If you are too small, you can't disassemble it. If the torque is too large, it will break the bolt. Ordinary electric wrenches or pneumatic wrenches are all impact-type tightening or dismounting methods. Compared with hydraulic wrenches, the speed is fast, but the damage to the bolts is also very large. Compared with pneumatic wrenches or electric wrenches, hydraulic wrenches not only provide better bolt protection but also higher torque accuracy, so many industrial hydraulic wrenches are now a must.
