Abstract
A portable tool capable of being moved by persons, users and/or operators includes a motor; an actuable tool component at least connectable to the work cylinder; an add-on from a group at least including an extension, a connection and a fork, configured to be placed on the tool; and a controller connected to the motor and configured to determine presence of the add-on on the tool to selectively increase or reduce motor force and/or speed, depending on detected presence or absence of the add-on.
Claims11
Portable tool, capable of being moved by persons, users and/or operators, comprising:
- a motor;
- an actuable tool component at least connectable to the motor;
- an add-on from a group, at least comprising an extension, a connection and a fork, configured to be placed on the tool;
- a controller connected to the motor and configured to determine presence of the add-on on the tool to selectively increase or reduce force and/or speed, depending on detected presence or absence of the add-on.
Portable tool of any preceding claim, further comprising:
- a fluid reservoir;
- a pump connected to the reservoir and the motor;
- a work cylinder connected to an output of the pump;
- wherein the actuable tool component is connected to the work cylinder;
- a sensor in the recue tool connected to any one or more than one of the motor, the reservoir, the pump, the work cylinder, and the tool;
- wherein the controller is configured to receive measurement signals from the sensor;
- and
- at least one controlled valve in a hydraulic circuit defined by the reservoir, the pump and the work cylinder and connected to the controller, wherein the controlled valve and the controller are configured to selectively at least substantially block or open any fluid channel in the hydraulic circuit.
Portable tool according to any preceding claim, further comprising at least one performance sensor providing, to the controller, information for the controller to adapt tool operation to the information, wherein the sensor is configured to measure and provide the information on at least one performance parameter from a group, comprising:
- fluid pressure from the pump, current drawn by the motor, revolutions per time unit of the motor, torque supplied by the motor, power delivered and/or consumed by the motor, battery charge if the tool comprises a battery, rotational position of the motor, position and/or a movement of a piston in the work cylinder, approximation of an predetermined extension of the piston from the work cylinder, such as maximum and/or minimum extension, ambient temperature, fluid temperature, motor temperature, motor resistance, fluid resistance, controlled valve position, user and/or operator input, and the like.
Portable tool according to any preceding claim, further comprising at least one detector providing, to the controller, information for the controller to adapt tool operation to the information, wherein the detector is configured to determine and provide the information on at least one parameter from a group, comprising:
- presence of the tool component and/or an extension thereof, connection to a mains power supply, water intrusion into the tool, a low battery level if the tool comprises a battery, and the like.
Portable tool according to any one or more than one of the preceding claims, further comprising a battery, whereby the tool is self-contained without external connections, except for a power supply connector for charging the battery.
The tool according to any one or more than one of the preceding claims, wherein the tool is a rescue tool from a group of rescue tools, comprising:
- a ram;
- a spreader;
- a cutter, and the like.
Method of operating a portable tool, capable of being moved by persons, users and/or operators, wherein the tool comprises:
- a motor;
- an actuable tool component at least connectable to the motor;
- an add-on from a group, at least comprising an extension, a connection and a fork, configured to be placed on the tool;
- wherein the method comprises determining presence of tire add-on on the tool;
- and
- selectively increasing or reducing force and/or speed, depending on detected presence or absence of the add-on.
