Each truck has a member 21, Fig. 4, which is raised by rams 19, 20 to lift a pallet 14 from the supporting surface. Wheels 23, 24, provided with flanges 23À1, 24À1, which engage in the guide grooves, are driven by an hydraulic motor 25. The flexible pipe 12 lies in the groove as the trolley runs out of the lift. Fig. 6 (not shown), illustrates an hydraulic circuit for controlling the movements of the trolleys automatically. (For Figures see next column)
