Abstract:
1. A reaction arm for a power-driven torque intensifier having a housing with an axis, torque intensifier means and switching means for switching the torque intensifier means between high speed/low torque and low speed/high torque, so that when said reaction arm is in a first position, the torque intensifier means operates with high speed/low torque and said reaction arm is usable as a handle by an operator, and when said reaction arm is in a second position the torque intensifier means operates with low speed/high torque and said reaction arm can abut against a stationary object since the high torque can not be absorbed by the operator, wherein said reaction arm is configured so that when it is placed in said first position it activates said switching means so that said switching means connects said housing and said torque intensifier means with one another to change from low speed/high torque to high speed/low torque.
