Individual trusses should always be carried vertically to avoid lateral strain and damage to joints and members. Trusses installed manually are slid into position over the sidewall and rotated into position using poles. The longer the span, the more workers needed to avoid excessive lateral strain on the trusses. Trusses should be supported at joints and the peak while being raised. Large trusses should be installed by a crane or forklift employing chokers, slings, spreader bars and strong-backs to prevent lateral bending. Trusses may be lifted singly, in banded groups, or in pre-assembled groups or rafts. Tag lines should always be used to control movement of trusses during lifting and placement. Workers should always use all appropriate safety equipment. Storage of Materials During Installation Care must be taken, after truss installation, not to overload trusses with the storage of other building materials. Under no circumstances should any materials be stored on top of unbraced trusses! Reference Document Refer to the CFSC Cold-Formed Steel Building Component Safety Information document CFSBCSI before handling or installing trusses. This document is available from the CFSC at www.cfsc.sbcindustry.com Lift shown using a spreader bar to distribute the load. Tag lines must be used during lifting.
