Truss Inspection
To relevant British and European standards
During the design phase, our design engineers validate our products through calculation and this forms part of the technical file required for the product to enter service. Further validation testing is then carried out during the manufacturing process with our engineers performing performance and functionality testing so that all products are fit for purpose and technically correct.
Before your equipment is put into service
In the United Kingdom equipment such as aluminium truss could fall under the Lifting Operations and Lifting Equipment Regulations (LOLER) or the Provision and Use of Work Equipment Regulations (PUWER), so pre-use checks need to be carried out by a competent person before it is put into service, and equipment not suitable for use removed from service.
For fixed installations, a proof load test may be required by law and is a process that comprises of an examination under a Report of Thorough Examination (ROTE) and maybe validation load testing to demonstrate that the solution is structurally sound, fit for purpose and safe to use.
TRUSS UK OFFER TRUSS INSPECTIONS BY COMPETENT ENGINEERS
How often must truss be thoroughly examined?
Truss inspections are a legislative requirement. Pre-use checks should be carried out every before each and every use by a competent person. The Provision and Use of Work Equipment Regulations (PUWER) require the inspection of work equipment that creates risk and The Lifting Operations and Lifting Equipment Regulations (LOLER) requires that a truss being used in a lifting operation needs to be inspected at least every 12 months in accordance with the regulation in force in the UK.
Here are some examples of what a truss inspection looks for:
- No (visual) cracks anywhere along the round tube, in or near the weld area (applies to both main chords and bracing)
- No bending out of the axis by more than 1 degree for main chords or 5 degrees for bracing
- Connection parts should have no dents, burrs, cracks or deformation, and should be clean without apparent corrosion
- Spigot pins shall be manufacturer originals and free of burrs, etc
- No holes except to made by the manufacturer for connection system purposes (applies to both main chords and bracing)
- Dents or other types of distortion of the cross section shall be less than 10% of change (dents in a 50mm chord shall be no deeper than 5mm) and for bracing dents shall be a depth of less than 10% of the diameter
- Bolts for connection parts shall be of the size and tensile strength as specified by the manufacturer
