Handling and Lifting Recommendations for Recommendations for 10 The installation of wood trusses requires the same high degree of safety awareness as the installation of any other structural material. It is essential that prudent methods be used at all times. Trusses may be installed manually, by crane, or by forklift, depending on truss size, wall height and job conditions. 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 place using poles. The longer the span, the more workers are needed to avoid excessive lateral strain on the trusses. Trusses should be supported at joints and the peak while being raised. Large trusses require the most planning and attention before lifting and should be installed by a crane or forklift employing chokers, slings, spreader bars and strongbacks to prevent lateral bending. Trusses may be lifted singly, in banded groups, or preassembled in groups. Planning ahead is essential before lifting any truss. First determine the proper location of lift points and the type of rigging and lifting procedure that will assure truss balance. Tag lines should always be used to control movement of trusses during lifting and placement. IMPORTANT SAFETY INFORMATION: Refer to BCSI Guide to Good Practice for Handling, Installing, Restraining & Bracing of Metal Plate Connected Wood Trusses for more detailed information. This publication is jointly produced by the Truss Plate Institute and Wood Truss Council of America for proper methods of installation. Installation procedures are the responsibility of the installer. Job conditions and procedures vary considerably. Every project has different site conditions that can have an effect on the erection process. Before the first truss is erected every individual involved needs to understand the installation plan and the intended bracing requirements for a safe, efficient and accident-free jobsite. These are only guidelines and may not be proper under all conditions. Visit www.sbcindustry.com for specific details.
