摘要: A system for deploying a vehicle arresting device (1) of the type comprising net (3) or other flexible substrate intended to lie flat upon ground with an array upwardly-directed spikes (4) attached along its leading edge, and which is adapted arrest by penetrating wrapping around front tyres pulling tight under stop further rotation wheels. The deployed across road (2) from folded condition on one side through cables (6) (7) edge wound in winch (5) opposite road, while anchored lanyards (12) (13) first road. each extend at divergent oblique angles. are themselves positions (14) (16) spaced so that it can self-correct fore aft direction during deployment arcuate movement about their anchor points.
