Before your equipment is put into service

Testing and thorough examination of a lifting appliance or lifting gear are required to be conducted by a competent person before it is put into use for the first time. A proof load test may be required by law and is a process that comprises of a thorough examination, a test and then a re-examination, and is required to demonstrate that the lifting solution or equipment is structurally sound, fit for purpose and safe to use. Thorough examination is a legal requirement to allow a piece of equipment to be put into service under the Lofting Operations and Lifting Equipment Regulations (LOLER).


How often must truss be thoroughly examined?

Truss inspections are a legislative requirement. Pre-use checks should be carried out every time a truss is used and before it is lifted. PUWER 1998 (Provision and Use of Work Equipment Regulations) requires the inspection of work equipment that creates a risk and LOLER 1998 (Lifting Equipment and Lifting Operations Regulations) requires that a truss lifting any load have a recorded Thorough Examination, which can be in accordance with either a formal scheme or a diarised/calendar approach.

Here's some examples of what an 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 (Truss UK)
