Abstract

The high-strength light-weight hollow boom (31) for a multi-section telescopic crane boom (15) comprises a top wall (T1), a bottom wall (B1), and a pair of lateral walls (S1). Each lateral wall is located between the top wall and the bottom wall. Each of the four walls comprises a pair of spaced longitudinally extending sections (51), and a relatively thin plate (52) extending between, overlapping and welded to the pair of longitudinal sections. Longitudinally spaced transversely extending stiffeners (53,54) of U-shaped cross-sections are welded to the plate and to the pair of longitudinal sections. Each longitudinal section of a lateral wall is in edge-wise abutting relationship with and welded to the surface of a longitudinal section of one of the top and bottom walls. Each stiffener of a lateral wall also its ends abutting the surface of a longitudinal section of the top and bottom walls.
