Patent number: 3952836Abstract: A composite transfer device for conveying material used in the construction of high tower-like structures, from a loading position at the base of the structure to a working platform which is raised as building proceeds. The device includes portions giving horizontal and vertical movement of a container, and includes a first transport unit at the loading level, a vertical hoist, and a second transport unit mounted on the working platform. The second transport unit includes a radial track movable around the working platform to deliver materials from the hoist, which is centrally situated, to different working areas around the structure. A special feature of the device is the use of a carrier frame which is square in plan view and which is supported on two hoist ropes attached to opposite corners of the frame, and which is also guided by guide tubes connected to the remaining two corners of the frame and which are located by downwards travelling reaches of the hoisting rope.Type: GrantFiled: September 27, 1973Date of Patent: April 27, 1976Assignee: Linden-Alimak ABInventor: Jozsef Thoma
