5.9.8 Spreader Beams
This is a device which is used when headroom is restricted and the wide spacing of lifting points would require along the sling to maintain the 90° included angle. Alternatively, they are used when the load will not sustain the compressive force applied by slings used at an angle. Spreader beams must be commercially made, unmodified, labeled indelibly with SWL, or if ‘homemade’, tested by subcontractor and approved by Owner.
