For a lattice boom crane, lattice mast element for such a lattice boom and crane with such a lattice booms

摘要

Lattice boom (7) for a crane (1) comprising a plurality of in each case with a gittermast element-longitudinal axis (14) along a lattice boom boom-longitudinal axis (12) arranged one behind the lattice mast elements (13; 23; 29; 38).a. each lattice mast element (13; 23; 29; 38) has a perpendicular to the gittermast element-longitudinal axis (14) oriented gittermast element-wide (b), which in a working arrangement is greater than 4 m, andexample, each lattice mast element (13; 23; 29; 38) in the working arrangement for a transport of the lattice mast element (13; 23; 29; 38) falls below a permissible length.
