Assembly of a first load carrier in the form of a pallet - with a load platform which has a load surface for cargo on the upper side thereof, - with skids which are arranged on the underside of the load platform, - with first contours which are formed on the upper side of the load platform, - with second contours which are arranged in a support surface of the skids, - wherein the first and second contours (18, 25) are designed so that at least areas thereof complement each other in form and arrangement so that when two pallets of the same kind are stacked one on top of the other the first contours of the first pallet engage in the second contours of the second pallet to secure the load, and of a second load carrier in the form of an optionally collapsible crate - having two opposing end walls, two opposing side walls and a bottom, which together form a cargo accommodating space, - with third contours which are formed by free edges of the front and side walls (30, 31), - with fourth contours which are formed by the crate bottom on the side of the crate opposite the cargo accommodating space, wherein the third and fourth contours (32, 34) are designed so that at least areas thereof complement each other in form and arrangement so that when two crates of the same kind are stacked one on top of the other the third contours of the first crate engage in the fourth contours of the second crate to secure the load, wherein - the first contours of the pallet are designed so that at least areas thereof complement the fourth contours of the crate in form and arrangement, and wherein - the second contours of the pallet are designed so that at least areas thereof complement the third contours of the crate in form and arrangement so that when the crate bottom is placed on the load surface of the pallet contours engage in each other to secure the load, and contours also engage in each other to secure the load when pallets are placed on crates, characterized, in that - banding grooves are provided between the skids on the underside of the load platform, wherein - the load platform has a structure consisting of individual ribs, and supporting struts are arranged two adjacent ribs in the area of the respective banding groove to prevent damage to each outermost rib of the pallet when a banding strap is tightened. - with a load platform which has a load surface for cargo on the upper side thereof, - with skids which are arranged on the underside of the load platform, - with first contours which are formed on the upper side of the load platform, - with second contours which are arranged in a support surface of the skids, - wherein the first and second contours (18, 25) are designed so that at least areas thereof complement each other in form and arrangement so that when two pallets of the same kind are stacked one on top of the other the first contours of the first pallet engage in the second contours of the second pallet to secure the load, - having two opposing end walls, two opposing side walls and a bottom, which together form a cargo accommodating space, - with third contours which are formed by free edges of the front and side walls (30, 31), - with fourth contours which are formed by the crate bottom on the side of the crate opposite the cargo accommodating space, - the first contours of the pallet are designed so that at least areas thereof complement the fourth contours of the crate in form and arrangement, and wherein - the second contours of the pallet are designed so that at least areas thereof complement the third contours of the crate in form and arrangement so that when the crate bottom is placed on the load surface of the pallet contours engage in each other to secure the load, and contours also engage in each other to secure the load when pallets are placed on crates, - banding grooves are provided between the skids on the underside of the load platform, wherein - the load platform has a structure consisting of individual ribs, and supporting struts are arranged two adjacent ribs in the area of the respective banding groove to prevent damage to each outermost rib of the pallet when a banding strap is tightened.
