Abstract
A truck restraining apparatus has a vertically extending jackscrew (18) to which a follower nut (38) is mounted. A hook shaped restraining member (36) is resiliently coupled to the follower nut and moves therewith when the jackscrew is rotated. The hook shaped member engages the ICC bar of a truck to restrain it from moving, while the resilient coupling compensates for float.
