Abstract
Abstract On a shipping pallet made of plastic, with two parallel surfaces forming its upper side and its underside respectively, whereby each surface is the outside of the base of two basic components permanently connected to one another, the bases of which are located at some distance from one another, the base of each basic component is a closed plate. The space between the bases of the basic components is bridged by a pair of strips parallel to one another and enclosing a groove between them. On both ends of each pair of strips the groove is closed by a cross member connecting the two bases to form a chamber. The space between the bases along the circumference of the pallet is closed by edge strips. The pallet is provided with feet projecting outward from a surface, and equipped with skids if necessary, and the two basic components are tightly connected to one another in the vicinity of the strips and cross member.
