Abstract: The invention relates to a demolition robot (1), comprising a cable (12) intended to be connected to an electric network to power a motor (21), a pump (22) that is powered by the electric motor for generating a hydraulic flow to consumers (13), wherein the motor (21) is activable at varying thermal load values (PT), depending on the current consumer's (13) need for hydraulic power, a control unit (24) arranged to receive information about the thermal load (PT) on the motor, to determine a partial thermal damage value (SL, SM, SH) at various thermal loads (PT) on the motor. To minimize the risk of thermal damage to the motor, the control unit (24) is adapted to compare said partial thermal damage values (SL, SM, SH) with a normative partial thermal damage (A) and is adapted to limit the thermal load (PT) on the motor (21) to a maximum allowable thermal load value (PTmax), if the partial thermal damage value (SL, SM, SH) exceeds the normative partial thermal damage (A) at a predetermined value (A?).

Abstract: A demolition robot (1) comprises a robot arm (2) and a saw tool (3) having an exchangeable saw blade (5), wherein the saw tool comprises a rotatable spindle (4) with an end portion (4.1) and a saw blade comprising a hub (6), and the saw blade hub is releasably arranged on the end portion (4.1) of the spindle with a torque-transmitting connection (7), and wherein a release mechanism (30) for automatic exchange of the saw blade (5) is arranged on the robot arm.

Abstract: A remote-controlled demolition robot has improved field of application The demolition robot includes a chassis, a base with a rotatable top, a moveable arm, a working tool, a controller, and a remote-control intended to be impacted by an operator. The demolition robot is arranged to give commands that are registered by the controller for operation of the remote-controlled demolition robot. The demolition robot also includes a broadcaster and an image sensor, which can register first image data and second image data of a scene of surroundings of the demolition robot from at least two different view directions. The broadcaster can communicate with an image display, which is arranged to show, in real time, an image area of the scene to an operator, who can control and operate the demolition robot through indirect viewing.

Abstract: The invention relates to a solution for presenting information describing a running operating condition of a demolition robot (3:1), provided with a microprocessor (24), a memory (26), wherein current data are obtained by sensors (21) as well as recorded and compiled into a data file (db1:1-db1:n) for each recording instance.

Abstract: A power supply system can be used for an electric motor that drives a hydraulic pump in a demolition robot. The system provides a DC current from a source of power, controls and monitors the voltage level (VDCnom) of the DC current, can be activated, and supplies a pre-determined load current (IL) from the source of power to the electric motor. In order to offer improved operational availability and flexibility, the load current (IL) can be constituted by a DC current, and the electric motor can be a DC motor.

Abstract: A portable power supply system supplies a remotely controlled, electrically driven work machine with electrical power. The work machine includes continuous tracks and is equipped with a maneuverable arm that carries a tool at its free end. An electric motor is connected to a hydraulic pump and supplies the machine with a hydraulic medium. The work machine is connected under normal operation to a primary source of power via an electrical cable. The primary source of power includes a fixed alternating current electricity distribution grid at the location. In order to be able to supply the current that is required it includes a DC energy-storage arrangement that, including a secondary source of power, can store energy and, when necessary, supply energy in electrical form. A coupling arrangement makes it possible to choose between connecting the motor to the primary or the secondary source of power.

Abstract: An arrangement for removable coupling of a tool with a working machine includes a first part with opposing indentions, which is supported by the tool, and a second part that is supported by a maneuverable arm, which includes shafts to be introduced into the indentations, a lever with which the shafts can be moved away from each other, and a locking mechanism for the displacement of the shafts. One of the shafts is united at a joint with a first arm section, and another shaft is united at a joint with a second arm section. The arrangement also includes at least one knee lever joints, one of which demonstrates two levers united with the shafts.
