Abstract
An extendible shield for sheltering the pit area below a dock leveler of a loading dock. The shield is especially suited for dock levelers having a ramp of pivotally adjustable height with a lip extension for providing a traffic path between the rear of a vehicle and a loading dock platform. The shield includes a curtain wrapped around a roller, which provides the shield with a vertical span that can vary to match the up and down movement of the ramp. Various embodiments include features such a flexible seal that seals against the rear of a vehicle and cutouts for accommodating a vehicle restraint and lip keepers.
