| 摘要 | The present invention is a pivoting pit seal assembly that forms a continuous seal with the rear bumper of a trailer parked in the bay of a loading dock, and which combines with the side and top seals of the loading dock to provide a 360 degree seal around a trailer. The pit seal assembly has a compression pad mounted to a rigid base. The pad has a resilient, compressible core material wrapped by a durable cover. One side of the base is pivotally held by brackets and corresponding releasable latches anchored to the front wall adjacent the pit floor or directly to the pit floor. During use, the pit seal is held in an upwardly angled position to compressingly engage the rear bumper of the trailer and form a continuous seal with the bumper. Each side end of the pit seal sealingly engages the vertical side seals located along the sides of the door opening to form a continuous seal between the pit seal and the side seals. To clean or access the pit, the releasable fastener is unfastened and the pit seal is rotated to a reclined position. | ||||||
