Publication number: 20220226979Abstract: A hydraulic tool includes a tool head and a moveable piston coupled to the tool head. The hydraulic tool head includes a plurality of jaws, which are operable to open and close for performing work on a workpiece. The hydraulic tool also includes a motor operable to drive the moveable piston to close the plurality of jaws to a closed position at which the work on the workpiece is completed. The hydraulic tool further includes a position sensor configured to detect when the plurality of jaws are at the closed position and responsively generate a sensor signal indicating that the plurality of jaws are at the closed position. Additionally, the hydraulic tool includes a controller configured to receive the sensor signal from the position sensor. The controller is configured to operate the motor based on the sensor signal that the controller receives from the position sensor.Type: ApplicationFiled: April 5, 2022Publication date: July 21, 2022Inventors: Luke J. Skinner, Kris J. Kanack, James G. Ballard, David R. Bauer, Troy A. Marks, Marc S. D'Antuono, Paige L. Bovard, Eric Norquist
