ABSTRACT:
An automatic torque wrenching machine comprises a frame having a support member which can be raised and lowered by admitting air to or allowing air to leave a pneumatic bellows. A tong assembly is suspended from the support member by four ties comprising wire ropes each of which is provided with a spring. The pneumatic bellows allows pipes to be connected and disconnected with minimal risk of damage to the threads. In addition, the ties enable the tong assembly to float in a generally horizontal plane relative to the frame.
