Abstract: A vehicle arresting device (1) comprises a net (2) of circular or polygonal planform adapted to lie flat on the ground in the path of a vehicle (14) to be arrested, with one or more rows of upwardly-directed spikes (6) attached to the net around its outer periphery. When a vehicle runs over the device, from any relative angle of approach, some of the spikes become imbedded in its front tyres and the net is caused to, wrap around the front wheels, the portion of the net between those wheels being pulled tight under the vehicle so that the tension in the net prevents further rotation of the wheels and the vehicle is brought to a stop. A deployment method for the device is also described where it is dropped in a folded condition from a helicopter or other aircraft or from a road vehicle into the path of a target vehicle and unfolds automatically on the ground.

Abstract: A track laying vehicle such as an EOD robot has an endless track on each side driven by a respective sprocket, and the vehicle is supported by a series of road wheels running on the tracks along each side. Each track comprises a series of tangs extending oppositely to the ground-engaging surfaces of the track and the road wheels are in parallel pairs to define circumferential grooves through which the tangs pass when the tracks are driven. The dimensioning of the tangs and grooves is such that the tangs are positively nipped by the road wheels during their passage to prevent the track from dropping out if not in contact with the ground—for example when the vehicle crosses a ditch or climbs over an obstacle—and resists shedding of the track in such circumstances.
