  • Method and arrangement for limiting the damage to a mine clearance vehicle in the event of large mine detonations
    Patent number: 6644167
    Abstract: The present invention relates to a method and an arrangement to mitigate damage to a rotary cultivator type mine clearer. In the event of detonations, triggered by the mine clearance tool, the present invention acts to mitigate damage to the mine-clearing tool, the mechanical mine clearer drive function, and its suspension. Detonation forces are, in a first stage, damped by hydraulic and/or mechanical damping members which are coupled between the bearing points of the tool and the engine driving the tool and which connect those parts to form a combined unit. If the detonation force is not absorbed, then, in a second stage, the detonation force remaining after the first stage damping, is counter to some of the combined weight of a unit formed by the tool, its bearings and the engine driving the tool.
