The invention relates to a method and a construction and/or a materials-handling machine for guiding and moving a working head, in particular a 3D print head, wherein at least three revolving tower cranes are attached to each other with their booms, wherein according to one aspect of the invention a guide beam carrying the working head is attached to at least two trolleys of two revolving tower cranes, and the working head is adjusted and moved in its working position by moving the trolleys along two booms of two revolving tower cranes.

The invention relates to a tower crane having a tower which carries a jib, from which a hoisting cable runs off, wherein a guying system is provided and runs, at least in part, along the tower and is spread out, by means of guy supports, in a direction transverse to the longitudinal center plane of the crane, this plane running through the tower and the jib, wherein at least one pair of guy supports which are spread out in a V-shaped manner are articulated on the tower, between the lower end of the latter and the jib.

A lower mast is attached to a base having fork pockets, and is pivotal between vertical and horizontal positions. A lower mast brace assembly has a receiver configured to receive the lower mast as it is moved into the generally vertical position, and to retain it there. An upper mast having a hoist at its upper end slides into the lower mast. The upper mast has a dogleg that offsets the hoist forward of the centerline of the lower mast. A hook is attached to the lower mast brace assembly near the receiver. The hinge, the lower mast brace assembly, the dogleg of the upper mast, and the hook are arranged so that the hoist may be used to pull the mast from the horizontal position to the vertical position. A combination limit switch, buffer, and vertical shutoff switch may be attached to the upper end of the upper mast.

The disclosure relates to a crane (200) for erecting a tower including a plurality of tower segments (171, 72, 173, 174, 175), the crane (200) comprising: a telescopic mast (210), and a jib (230) rotatably mounted with respect to the telescopic mast (210) and comprising lifting equipment (240). The telescopic mast (210) comprises a lower mast segment (211) having one or more lower clamp assemblies (202, 204) for selectively gripping portions of the tower and a roller assembly (300) for rolling along the tower, and comprising one or more further mast segments (212, 213, 214, 215, 216) having an upper clamp assembly (206) for selectively gripping portions of the tower, the further mast segments (212, 213, 214, 215, 216) being slidable with respect to the lower mast segment (211). The disclosure also relates to methods for climbing a tower with a crane (200) and methods for mounting a wind turbine tower.

The present invention relates to a lifting assembly (1) for elevating components to a wind turbine (5). The lifting assembly comprises a plurality of tower segments (13) which together form an elongated tower (9), a support frame (11) for supporting the tower (9), a securing assembly (32) securing the tower (9) to the wind turbine (5). The lifting assembly (1) further comprises an upper platform (7) provided with and a crane (21) and vertically movable along the tower (9), and a lower platform (8) provided with a storage area (16) for supporting components and vertically movable along the tower (9) between the upper platform (7) and the support frame (11).
