A commercial dishwashing system has an elongated table structure extending through a dishwasher, the table structure having a longitudinal gap therein and a top side forming a portion of a closed conveyance path. A roller gate is pivotable between a lowered position in which the gate blocks an upper portion of the gap and defines the balance of the closed conveyance path, and a raised position in which the gate unblocks the upper gap portion. A drivable chain, having vertically pivotable links, is used to releasably engage and longitudinally move wash racks around the top side of the table structure. The bottom side of a downwardly extending loop of the chain horizontally extends across the gap at a step-over height. With the gate lifted a worker may access the horizontally inner side of the dishwasher simply by stepping over the bottom chain loop side and walking inwardly through the gap.
