Abstract:
A connector for a column segment, such as a boom segment, of a crane includes n extensions, where n is a positive integer. Each extension has a first base and an aperture extends through the extension from a first side to a second side. The first connector also includes at least (n+y) plates, where y is selected from the group consisting of (−1, +1) such that the sum of (n+y) is a positive integer. The plate or plates are positioned in and coupled to the extensions in an alternating arrangement. Each plate includes a plate base aligned substantially in a plane with the first base of the extension to form a first connector mounting surface. A plurality of welds couple the plates to the extensions and the fabricated connector is then welded to the column segment. At least one extension is formed of steel having a grain structure elongated in a direction of rolling that is substantially perpendicular to the first base.
