LATTICE-MAST ELEMENT, LATTICE-MAST JIB HAVING AT LEAST ONE SUCH LATTICE-MAST ELEMENT, AND CRANE HAVING AT LEAST ONE SUCH LATTICE-MAST JIB

摘要

A lattice-mast element (15) for a crane comprises at least two longitudinal elements (21) and at least one transverse element (22), which connects the longitudinal elements (21) to one another, and at least one reinforcing element (24) for reinforcing the lattice-mast element (14; 15; 16; 54; 56; 57; 58) by connecting the longitudinal elements (21) and/or the transverse element (22) to one another, wherein the longitudinal elements (21) and the transverse element (22) bound a bearing-load surface of the lattice-mast element (15) and the longitudinal elements (21) are each configured in the form of a two-dimensional load-bearing structure.
