  • Patent number: 4901650
    Abstract: An industrial pallet is constructed and arranged to support a vertical stack of scaffold end frames on the pallet's rectangular, horizontal support platform. Upwardly extending channel-iron members are rigidly secured adjacent the back edge and the two side edges of the platform. These channel-iron members define an open-front cavity for receiving the end frames as they are manually inserted onto the platform from the front edge thereof. Horizontal hand-rail/brace members extend between the side disposed channel-iron members, to form both hand rails and a platform for supporting tube-shaped scaffold cross members that are used with the scaffold end frames when constructing a scaffold. Two vertically extending, removable, locking rods fit into sockets carried by the platform. When these locking rods are manually inserted into the platform sockets, the rods penetrate interior spaces of the stacked scaffold end frames.
