Telescopic crane beam with greater and lesser curved profile segments in the upper and lower profile part

摘要

The part has an upper profile part (10) and a lower profile part (20) that includes curved cross-sectional areas. The profile parts (10, 20) are welded with each other at a connection point (2), and have segments (16, 24, 26) that are bent outwardly. End segments (12, 14, 22, 24) are adjacent to each other at the connection point, and run outwardly in an oblique manner. The end segments lie each other and/or are adjoined to each other at an obtuse angle, where the radius (Rus) of the segments (16, 26) is less than the half width of a cross-section.
