摘要 An upstanding support structure is provided defining an elevated horizontally elongated stationery platform extending along one side of the support structure and a horizontally elongated second platform is mounted, in cantilever fashion, from the one side of the support structure for vertical shifting relative thereto so as to be downwardly displacable over the upper portion of an elongated bulk material receiving vehicle disposed along side the one side of the support structure adjacent the lower end thereof. The second platform includes a first side fence extending along the side thereof adjacent the support structure as well as end fences extending across the ends of the second platform and appreciably outwardly beyond the outer side of the second platform.
