Abstract
A hydraulic torque wrench and method of operation. The wrench may include a housing supporting a drive element for engaging a fastener; a drive actuator for exerting a torque on the drive element; a sensor configured to sense movement of the housing; and a controller having an electronic processor, the controller being configured to receive a first signal from the sensor, determine, based on the signal, whether the housing is moving, and inhibit operation of the drive actuator in response to the housing of the hydraulic torque wrench moving.
Claims26
A hydraulic torque wrench comprising:
- a housing supporting a drive element configured to engage a fastener;
- a drive actuator configured to rotate the drive element in a first direction;
- wherein the hydraulic torque wrench is configured to engage a reaction surface to prevent rotation of the hydraulic torque wrench in a second direction opposite the first direction when the drive element is engaged with the fastener and the drive element is operated;
- a sensor configured to sense said rotation of the housing in the second direction;
- and
- a controller having an electronic processor, the controller being configured to determine that the housing is disengaged from the reaction surface and inhibit operation of the drive actuator upon receipt of a signal from the sensor indicating said rotation in the second direction.
