ABSTRACT:
A dock (D) is provided with a reciprocating slat conveyor (12). A trailer (T) is provided with a reciprocating slat conveyor (10). The dock (D) includes a dock end (100) that includes mechanism for aligning the trailer conveyor (10) with the dock conveyor (12). This mechanism includes a guide rail 108 that is secured to a vehicle supporting apron (106) and is positioned to fit between the wheels (W) on one side of the rear of the trailer, for guiding the wheels towards the dock (D). The dock end (100) includes lifting rods (18, 20) which include lifting cams (22, 24). The cams (22, 24) are initially positioned below rear corner portions (14, 16) of the trailer (T). The lifter rods (18, 20) are then rotated to move the lifting cams (22, 24) up into a lifting position against the corner portions (14, 16). The lifter rods (18, 20) and cams (22, 24) are rotated to effect a vertical adjustment in position of the trailer conveyor (10) relative to the dock conveyor (12). A pair of positioning beams (126, 128) are located between two vertical frame members (122, 124) that are a part of the rear end structure of the trailer. The beams (126, 128) are pulled apart, with one of them going against one of the vertical frame members (122, 124), if necessary, for correcting the horizontal alignment of the rear end of the trailer (T).
