ABSTRACT:
A torque intensifying tool for tightening and loosening threaded connectors has at least one torque intensifier unit with a torque intensifier housing portion, an input and a first output and a second output, a drive connected with the input unit for transmitting a torque from the drive through the intensifying unit to a threaded connector, so that in one mode of operation the housing portion together with the first and the second outputs turn in the same direction, and in another mode of operation the housing portion together with one of the first and second outputs receives a turning force in one direction while the other one of the first and second outputs receives an equal turning force in the opposite direction, and so that one of the first and second output means turns in the one mode and in the another mode while the other of the first and second output means turns in the one mode and reacts in the another mode.
