Lattice mast element, crane equipped with at least one of the lattice boom of lattice boom and this type comprises at least one of the lattice mast element of this type

摘要

Which has a [problem] high load carrying capacity, to be able to easily transport. A A lattice mast element crane (15), at least one longitudinal element (21), at least one transverse element (22) interconnecting the longitudinal elements and longitudinal elements comprises at least one bracing element reinforcing the lattice mast element (24) and / or the transverse elements by interconnecting. In this case, the longitudinal elements and the transverse elements defining a load bearing surface of the lattice mast element, constituted a plurality of longitudinal elements as each two-dimensional load-bearing structure.FIELD 4
