They are formed on the basis of single-piece moulded pillars or feet 1, with end openings 2,3, arranged along orthogonal axes, into which are slipped battens 4 for supporting the grip 7, which battens form at least one of the faces of the platform, the feet being fixed by nailing, by positioning of adjacent battens 7 or by means of both systems. The feet 1 have their hollow structure crossed by partitions 8,9 which connect, in pairs, the faces of the hollow section, and they have at least the lower end wall equipped with rounded reliefs 10 forming sliding runners. They are used for lifting and transporting all types of load. <IMAGE>
