  • Mine detonating apparatus
    Patent number: 9062940
    Abstract: A steerable mine detonation apparatus is adapted to be pushed by a steered vehicle. The apparatus comprises a frame and at least two spaced apart ground engaging members adapted to support the apparatus and adapted to exert a force on mines in the apparatus' path sufficient to cause detonation thereof. At least one ground engaging member is steerable, and at least one steerable ground engaging member is attached to the frame so as to pivot with respect thereto about a substantially vertical axis and is connected to a steering linkage, the apparatus further comprising a steering mechanism operatively connected to the steering linkage and, in use, to the pushing vehicle. An actuator is adapted to vary the configuration of the steering mechanism.
