A reaction arm (31) for a power-driven torque intensifier having a housing (1) with an axis, a torque intensifier unit and a switching device (19) for switching the torque intensifier unit between high speed/low torque and low speed/high torque, is configured for operating the switching device (19) so that when the reaction arm (31) is placed in a first position, the torque intensifier unit is switched to high speed/low torque and the reaction arm (31) is usable as a handle by an operator, and when the reaction arm (31) is placed in a second position the torque intensifier unit is switched to low speed/high torque and the reaction arm can abut against a stationary object since the high torque can not be absorbed by the operator. |
