Racking beam with a bearing portion, a guiding portion, and a stiffening portion, with the stiffening portion disposed along a longitudinal edge of the bearing portion

摘要

Disclosed is a racking beam (10) for an open faced racking system. The beam comprises of a bearing portion that incorporates a bearing surface (13), a guiding portion that is disposed along a first longitudinal edge of the bearing portion, and a stiffening portion disposed along a second longitudinal edge of the bearing portion. The guiding portion extends upwardly from the bearing surface. The stiffening portion extends downwardly and inwardly from the bearing portion by an amount sufficient to cause a principal axis X of bending of the beam to be oriented within 20 degrees relative to a nominal plane of the bearing surface, and the shear centre S of the beam to be positioned so as to be laterally displaced from the second longitudinal edge within the range of +30% to -10% of the width of the bearing surface extending between the first and second longitudinal edges.
