Abstract
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.
Claims37
A construction and/or materials-handling machine for erecting a structure and/or manipulating a workpiece, comprising:
- a working head movably mounted on a supporting frame structure, wherein the supporting frame structure has at least three tower slewing cranes which each comprise an upright tower and at least one boom which is supported by the respective tower and is configured to be rotated about an upright slewing axis relative to the tower or together with the tower, wherein the tower slewing cranes are attached to one another by their booms and form a polygonal support frame,
- wherein the revolving tower cranes are each a mobile crane, wherein each mobile crane comprises an undercarriage with a travelling gear which is movable on the ground, and a rotary platform which is mounted on the undercarriage so as to be rotatable about an upright slewing gear axis and on which the tower of the revolving tower crane is mounted.
A construction and/or materials-handling machine for erecting a structure and/or manipulating a workpiece, comprising:
- a working head movably mounted on a supporting frame structure, wherein the supporting frame structure has at least three tower slewing cranes which each comprise an upright tower and at least one boom which is supported by the respective tower and is configured to be rotated about an upright slewing axis relative to the tower or together with the tower, wherein the tower slewing cranes are attached to one another by their booms and form a polygonal support frame,
- wherein the revolving tower cranes each comprise a climbing device for climbing tower pieces into and out of the tower of the respective revolving tower crane.
A construction and/or materials-handling machine for erecting a structure and/or manipulating a workpiece, comprising:
- a working head movably mounted on a supporting frame structure, wherein the supporting frame structure has at least three tower slewing cranes which each comprise an upright tower and at least one boom which is supported by the respective tower and is configured to be rotated about an upright slewing axis relative to the tower or together with the tower, wherein the tower slewing cranes are attached to one another by their booms and form a polygonal support frame,
- wherein the working head is suspended by a system of cables comprising at least three control cables from the revolving tower cranes attached to each other, further comprising cable winches for adjusting the control cables relative to the revolving tower cranes and/or relative to the working head.
