Abstract: This disclosure relates to an apparatus for erecting structures from flowable and settable material and includes a lifting unit having an open ended shell supported by a carrier pivotally attached to a medial portion of an arm disposed generally radially to the structure which is to be formed, a first pair of relatively telescopically movable inner and outer members connected to an outboard end of the arm in generally tangential relationship to the structure, first means for moving the inner and outer members telescopically relative to each other, and second means for moving the inner and outer members along the arm in a synchronous manner to that of the relative telescopic motion.

Abstract: 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.
