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.

A hydraulic implement (1) for portable use includes a hydraulic pump (2), a pump housing (10), a hydraulic cylinder (3) with a piston rod (11), a hydraulic tank (4), hydraulic lines, a compensating device, a manually operable hydraulic control valve (8), a rechargeable battery (9) which is accommodated on the implement (1), and two tool halves (16, 17) that are connected to the piston rod (11) via pivoting arms (12, 13). Each tool half (16, 17) has a wall section (20, 21) that extends perpendicularly to the extension of the longitudinal axis of the piston rod (11). When the tool halves are closed, both wall sections (20, 21) together form a flattened end region (24) that runs perpendicularly to the extension of the longitudinal axis of the piston rod (11).

In a method for installing a key locked insert to a workpiece, the workpiece has a hole open to a first surface. The method includes: threading an insert body into the hole; threading a first portion of a mandrel into the insert body; after the threading of the first portion into the insert body, mating a second portion of the mandrel with an actuator; and using the actuator to extend an anvil relative to the mandrel to drive keys of the insert through a thread of the workpiece hole.

A power tool including a moveable piston, a motor capable of driving the moveable piston to perform work on a work piece, and a distance sensor configured to sense a movement of the moveable piston. The distance sensor operable to provide sensor information indicative of the movement of the piston. A controller receives the sensor information from the distance sensor. The controller operates the motor to perform work on the work piece based in part on the sensor information that the controller receives from the distance sensor.
