  • Method and arrangement for preventing the passage of a mining vehicle
    Patent number: 6470989
    Abstract: The invention relates to a method and arrangement for preventing the passage of preferably an unmanned mining vehicle. The invention is based on the idea of providing a mining vehicle, such as a loading vehicle, with a mast (7) arranged on its upper outer structure and extending above other portions of the vehicle. In connection with the mast there is provided an emergency stop switch. Furthermore, at the upper portion of a mine gallery, or a similar operating site, is provided a barrier boom reachable to the mast for bordering the accepted travel area of the mining vehicle. If the mining vehicle tries to leave the accepted area, the mast hits the barrier boom and thus triggers the switch arranged in connection with the mast, thereby causing the mining vehicle to stop.

  • Automatic steering system for an unmanned vehicle
    Patent number: 5923270
    Abstract: The invention relates to an autonomous navigation system for an unmanned vehicle. The tracks or wheels are driven by hydraulic reversible motors, having the output thereof regulated by valves whose relative control can be used for controlling both heading and speed. The vehicle carries a navigation computer which receives positional information from an external positioning sytems. A ground station computer has been supplied with a digitized map over a predetermined path and the ground station computer is in a two-way radio communication with the vehicle navigation computer which is supplied with the information relating to the path. An established path, which is received from the external positioning system, is compared to the predetermined path and the vehicle navigation is modified for compensating the deviations.
