FIELD: machine building.
SUBSTANCE: group of inventions relates to mechanization of track facilities, in particular, to machines for screwing and unfastening fastening bolts of sleepers, as well as to methods of their operation. Machine comprises machine frame, manual grip for movement along rail track, engine and engine torque limiting device. Bolt rotation shaft is connected to the engine. Moment of reaction torque of engine is located opposite machine frame. Meter determines reaction torque of engine relative to machine frame. Engine is disconnected depending on engine reaction torque.
EFFECT: higher accuracy of measuring moment applied to bolt of rail fastening.
