FIELD: transportation.
SUBSTANCE: invention relates to a crane. Crane has at least one horizontally arranged span beam of a lattice structure with a number of struts where a crane trolley is mounted. Struts are plate-like. On each side of the struts in the main surface, the first and second recesses are formed. Lateral sides of the struts are flat without bends at least on the section between the notches.
EFFECT: longitudinal girder simplification is achieved.
