A loading yard is provided with a mounting structure for removably mounting a wharf on the yard. Horizontal guide rails of different configurations are mounted on the front end of the yard. The wharf includes a number of mounting brackets having rollers positioned in different orientations. The rollers are slidable over the guide rails to mount the wharf in a suspended manner on the front end of the yard. The yard has a top edge which extends outwardly beyond the front end to prevent vehicles from being driven too close to the front end to avoid damage to the guide rails.
