ELEVATING WORK PLATFORMS (EWP)

In addition to six monthly Mechanical Inspections and any Electrical HV boom and liner testing, an Acoustic Emission Test is required on all mobile elevating work platform's fitted with a fibreglass boom (FRP) every 2 years.  The test involves sophisticated equipment to detect any breaks or cracks in fibres as a load is applied and withdrawn over periods of four minutes. As required by AS/NZS 4748 - Acoustic Emission Testing of Fibreglass Insulated Booms on Elevating Work Platforms, this test must be carried out at two yearly intervals or if any damage has occurred through other reasons ie an accident.
