Abstract:
1. A method for automatically cycling a torque wrench comprising: a. providing a hydraulic torque wrench; b. providing a magnet on the hydraulic torque wrench; c. providing a switching device on the hydraulic torque wrench; d. adapting the switching device to be activated by the magnet when a piston of the torque wrench is at the end of a stroke; e. communicating a directionally controlled pump with the hydraulic wrench; f. setting an output pressure for the directionally controlled pump; g. communicating the directionally controlled pump with a processor; h. communicating the switching device with the processor; i. adapting the processor to cycle the directionally controlled pump, when the switching device is activated; and wherein the processor stops the directionally controlled pump when the sensed output pressure reaches the set output pressure and the switching device is not activated.
