Abstract
The invention relates to a crane, in particular to a mobile crane, comprising a lattice boom, a derrick boom, and a boom guying led from the derrick boom to the boom tip, wherein at least one guying frame is provided that is fastened to the boom between the derrick boom and the boom tip and is connected to the boom guying.
Claims18
A crane comprising a lattice boom, a derrick boom, and a boom guying guided from the derrick boom to a boom tip of the lattice boom, wherein at least one boom guying frame is fastened to the lattice boom between the derrick boom and the boom tip and is connected to the boom guying;
- wherein the at least one boom guying frame has a spatial lattice structure and comprises at least two side elements connected to one another along a length of the at least one boom guying frame, and each strand of the boom guying extending from the derrick boom to one of the at least two side elements and then to the boom tip, where the at least one boom guying frame transmits compressive forces and transverse forces to apply the compressive forces and the transverse forces to the lattice boom over the boom guying during crane operation;
- and
- wherein the boom guying is a luffing drive that operates the lattice boom.

- wherein at least one boom guying frame is fastened to the lattice boom between the derrick boom and the boom tip and is connected to the boom guying;
- wherein the at least one boom guying frame has a spatial lattice structure and comprises at least two side elements connected to one another along a length of the at least one boom guying frame, and each strand of the boom guying extending from the derrick boom to one of the at least two side elements and then to the boom tip, and each strand of the boom guying is connected to an adjustment block positioned between the derrick boom and the at least one boom guying frame, where the at least one boom guying frame transmits compressive forces and/or transverse forces to apply the compressive forces and/or the transverse forces to the lattice boom over the boom guying during crane operation;
- and
- wherein the boom guying is a luffing drive that operates the lattice boom.
