An example hydraulic tool includes: a fluid reservoir; a pump; an electric motor; a cylinder; a piston; a first trigger button; a second trigger button; and a controller configured to perform operations comprising: receiving a first signal when the first trigger button is triggered, responsively, causing the electric motor to rotate in a first rotational direction, thereby: (i) causing the pump to provide fluid to the cylinder, and (ii) causing the piston to move in a first linear direction, thereafter, receiving a second signal when the second trigger button is triggered, and responsively to the second signal, causing the electric motor to rotate in a second rotational direction opposite the first rotational direction, thereby: (i) opening a fluid path from the cylinder to the fluid reservoir, and (ii) causing the piston to move in a second linear direction opposite the first linear direction.

Hydraulic power tool

A working head for a hydraulic power tool. The working head includes a head frame and a first moveable die head configured to move along the working head frame. The first moveable die head is configured to receive a first moveable die comprising a first body length and a second die head is adapted to receive a second die comprising a second body length. At least one of the moveable die or the stationary die comprises an elongated die.

A bolt tensioning tool includes a housing, an electric motor positioned within the housing, a hydraulic pump positioned within the housing, the pump being driven by the motor to pressurize hydraulic fluid stored within the housing or a remote reservoir, and a tensioning assembly connectable to a bolt for applying tension thereto in response to an applied force by the pressurized hydraulic fluid.

Bolt tensioning tool

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.

Power tool

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.

A power tool system includes a hydraulic power tool. The hydraulic power tool includes a hydraulic drive, a sensor, and a first electronic processor. The sensor is configured to detect an operational parameter of the hydraulic drive during an operation by the hydraulic drive. The first electronic processor is configured to store a plurality of data points based on the operational parameter detected during the operation and send the plurality of data points to an external device. The external device includes a display screen and a second electronic processor configured to receive the plurality of data points from the hydraulic power tool, control the display screen to display an expected data point for the operational parameter for the operation, and control the display screen to display an actual data curve based on the plurality of data points, the actual data curve overlaid on the expected data point.

Hydraulic crimper tool

An example system includes a cutting tool and a device configured to remotely control the cutting tool. In response to receiving information indicative of actuation of a first user interface item, the device sends a first signal to the cutting tool so as to request enabling the cutting tool to be operated remotely. The cutting tool sends a second signal to the device indicating that remote operation of the cutting tool has been enabled. The cutting tool receives information indicating that the trigger has been activated, and sends a third signal to the device indicating that the cutting tool is ready to perform a cutting operation. The device receives information indicative of actuation of a second user interface item, and responsively, sends a fourth signal to the cutting tool so as to cause the cutting tool to perform the cutting operation.

Control of a cutting tool

A working head for a hydraulic power tool including a head frame and a first moveable die head configured to move along the working head frame. The first moveable die head configured to receive a first moveable die comprising a first body length. A second die head is adapted to receive a second die comprising a second body length. The first body length of the moveable die is different from the second body length of the stationary die.
