A transport wheel and rail assembly for the transfer of partition plates and support walls in packet moulds used in vertical casting of concrete elements, the plates and walls being provided with transport wheel assemblies movable along rails by means of rack and pinion drive mechanisms, the wheel assemblies in each plate or wall being arranged in such a way that part thereof travels along one side of a rail, the other travelling along the other side of the rail, thus making an overlapping arrangement of wheel assemblies belonging to adjacent plates possible. |
