AH15 is a tool designed for the rotation in the two senses of pipe drilling machines for hot tapping connections operations normally necessary in the maintenance of gas and water networks. For its exclusive characteristics AH15 can be used also for the rotation of other rotary devises like: gates irrigation canals, lifting/lowering of rail road devises, rotation of reductors, ecc. The tool features a “twist type“ control handle to turn clock wise and counter clock wise, ON/OFF control is proportional so can increase or reduce speed in both rotations modes, the torque force and the rotation speed can be adjusted by acting on the two valve that control these functions. The handle with spring return assures total safety, the rotation immediately stops when the operator releases the handle (“dead man” action) AH15 eliminates the fatigue and increases the productivity.
