Welcome to the new and old customers to buy! In the design of high-strength shear bolt crane specifications, friction-type connectors are high-strength bolts shear reach beyond the contact surface between the plate by tightening the bolts probable maximum friction force provided by the state as a limit, that is, to ensure that in the entire period of use does not exceed the maximum shear frictional force inside and outside.
