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.
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.
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:
