Abstract
Abstract The present invention relates to a pallet which is particularly, but not exclusively intended for use in cargo terminals or other stations where goods are transferred from one means of transportation to another to facilitate loading, unloading and reloading of goods, but which is also useful for the ordinary purposes of the pallet. Characteristic of the invention is that the pallet comprises a body in the form of a rectangular, relatively light-weight framework of light metal or aluminum beams with a load-carrying surface formed by a plurality of rollers, preferably in the form of ball roller means, connected to the framework, and with at least one brake roller which is supported in such a position that goods having planar undersides, which, when carried on the pallet, are moved on the rollers, will be braked by means of the brake roller which is preferably carried by a swiveling frame to permit braking in whatever direction the goods are shifted.
