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
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 strongbacks to prevent lateral bending.
Trusses may be lifted singly, in banded groups, or
preassembled in groups.
Tag lines should always be used to control
movement of trusses during lifting and placement.
Refer to Handling, Installing and Bracing Metal
Plate Connected Wood Trusses (BCSI 1-02) by the
Truss Plate Institute, or Wood Truss Erection poster
by the Wood Truss Council of America for proper
methods of installation.
Installation procedures are the
responsibility of the installer. Job
conditions and procedures vary
considerably. These are only
guidelines and may not
be proper under all
conditions.
