Its motor and gear have a long service life. It is ideal for using in bridge construction, high-rise buildings, metallurgical construction, power plant construction, chemical industry construction, etc.
Heavy duty electric shear wrench is designed to fasten or tighten torsional shear type high strength bolt or tension control bolt. The bolt has a splined end that will disconnect when the bolt’s tension reaches a predetermined value. That is to say, the splined end is sheared off means that the bolt has reached to the pre-tension.
Tightening of tension control bolt is done in two steps, namely, initial tightening and final tightening. For the initial tightening, the strength should reach the 60%-80% of standard axial force or pre-tension, and the initial torque value is not less than 30% of the final torque value. For the final tightening, the splined end will be twisted off. To ensure all bolts of bolt groups are uniformly loaded, the two processes should be performed or carried out orderly.
