HANDLING, ASSEMBLY, AND USE OF TRUSSES

Load, unload, or move trusses with the necessary personnel to assure that the trusses are
not dragged or dropped; this may damage the ends and the structure or result in other
unseen damage.

When transporting truss

- Ensure that trusses are secured to prevent bouncing;

- Ensure that nothing rubs against the trusses that might cause wear or puncture;
- Ensure that nothing is loaded onto the top of the trusses.

w w w. a rc o f a b. c o m
Load data

- Are only valid for static loads and spans with two supporting points (one at each end);
- Are to be considered for indoor use only. If dynamic loads or more supporting points
are applied contact a structural engineer or Arcofab;
- Are valid when the truss is used with the diagonals oriented vertically
(see attached figures in page G-3);
- Are valid when the end plates are installed vertically for the bolted trusses
(see figure in page G-3 – note 1);
- Are valid when the pins are installed horizontally for the spigoted trusses
(see figure in page G-3 – note 2);
- Take into consideration the self-weight of the trusses and indicate how much additional
weight may be safely added;
- Deflexions are theoretical (based on the rigidity of the truss when full loaded). Actual
deflexion may be slightly higher because of possible movement between truss sections
due to attachment tolerance;
- When corner blocks are used, loading capacity must be reduce by 50% when corners
are loaded on two adjacent faces.

HANDLING, ASSEMBLY, AND USE OF TRUSSES

Rigging, loading, and unloading

- Trusses should be assembled by competent personnel who are familiar with the use and
assembly of aluminum trusses;
- Always use washers on both sides of plates for bolted trusses;
- Trusses must be hung using bottom and top chords in order to ensure an optimal
stability. Spanset must be as close as possible to the extremities
(see figure in page G-3 – notes 3 and 4);
- Trusses must be loaded symmetrically on each side; unbalanced loads could twist
the trusses (see figure in page G-3 – note 5);
- All loads must be applied to, or as close as possible to, node points. A node point
is the meeting of diagonal and/or vertical on the main chord
w w w. a rc o f a b. c o m (see figure in page G-3 – note 6);
- When raising or lowering trusses, hoists should run simultaneously in order to maintain
the trusses leveled up;
- Always unload trusses before disassembling connections.

Inspection
Arcofab trusses are engineered and built to provide many years of reliable service provided
that they are used within the recommended loading parameters and handled properly.

To prevent undesired consequences that could occur when the manufacturer

recommendations are not respected, it is very important that all truss structures and
connecting parts be inspected regularly and documented by qualified personnel in order to
detect abnormal wear and abuse such as:
- Cracks in welds;
- Local permanent deformations in the structure;
- Dents or chew marks in the main chords or diagonals;
- Wear or bending in the attachment pin and spigot;
- Bending in the plates or distortion of bolt holes;
- Damage on zinc surface treatment or corrosion.
If any of the above failures is detected, do not use the piece.

Nuts, bolts, and washers should be replaced periodically as regular use degrades bolt
threads. Never over-torque nuts and bolts beyond manufacturer specifications and always
use Grade 8 nuts, bolts, and washers.

INSPECTION AND MAINTENANCE

Inspection
A visual inspection of each section is required before every use. Furthermore, a complete
inspection shall be performed at least once a year (or more often depending on the
intensity and frequency of use). Every piece shall be carefully inspected by a competent
person in order to guarantee the strength and safety. Documentation on inspection
shall be registered and kept on file. Every inspected piece shall be clearly marked and
easy to identify.

When truss sections show damage that might affect the safety aspect, it is mandatory to
discard and mark them clearly so they won’t be put back into service. Damaged sections
can be submitted to Arcofab for evaluation and repair if possible. Should you have any
doubt, please contact Arcofab technical department.

Discard criteria
w w w. a rc o f a b. c o m
Any truss showing significant visible damage or suspected of containing a damaged
element (visible or not) shall be removed from service and marked accordingly.
