FIELD: process engineering.
SUBSTANCE: invention relates to machine building, particularly, to devices intended for tightening and loosening of threaded joints. Proposed bench comprises torque generator including drive device with hollow shaft and disk chuck fitted on the shaft and provided with clamping hydraulic cylinders. Each of the latter comprises HP and LP chambers, delay device and hydraulic system. Hollow shaft of the drive device is provided with fixed sleeve. Two annular chambers are made on inner surface of said sleeve. Hollow shaft wall have channels to communicate one of said annular chambers with HP chambers of all clamping hydraulic cylinders and another annular chamber with LP chambers of said hydraulic cylinders.
EFFECT: easy, fast and low-cost assembly and disassembly of threaded joints.
