ABSTRACT:
The present invention relates to a storable vehicle restraint for securing a trailer to a loading dock. A mounting plate anchors a vertical track to the dock. A horizontal barrier is joined to the track and is movable between stored and raised positions. The barrier has a throat that receives the ICC bar of a trailer and a hook that is position in front of the bar to prevent the trailer from moving away from the dock. A cooperating drive unit and lift assembly allows the barrier to be stored at height of 9 inches and raised to a height of 30 inches, while providing a substantially uniform upward force to the barrier. A sensor having a switch to detect proper alignment with the ICC bar is positioned along side the throat of the barrier. The barrier forms a housing that protect the lift assembly, drive unit and sensor switch.
