1289448 Trolleys for loading lifts INVENTIO AG 29 April 1971 [5 May 1970] 12151/71 Heading B8E A lift car, Fig. 1, is loaded by a pair of separate trucks 9, 10, Fig. 2, which are driven synchronously with each other each by its own hydraulic motor mounted thereon, fed through flexible lines 11, 12 with pressure fluid from a pump unit in the lift car and guided by grooves 8À1, 7À1 in the floor of the car and the adjacent floors outside the car. 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) |
