According to the Approved Code of Practice for Power-Operated Elevating Work Platforms, an Elevating Work Platform (EWP) requires a major examination:

• After 10 years service and, thereafter every five years
• If 'imported used', prior to entering service in New Zealand

The major examination entails inspection in accordance with the requirements of clause 10.4 of AS 2550.10:1994 Cranes Safe Use Part 10: Elevating work platforms or equivalent. The thorough examination should include the disassembly and removal of paint, grease, corrosion from critical components to allow a complete and thorough inspection, the detailed visual inspection and tolerance checking of all wear components, and non-destructive testing of all critical areas for evidence of cracking, fatigue and excessive stress.

It should be noted that, although a later version of AS 2550.10 exists, this has not yet been supeceded in a revised ACOP. For the avoidance of doubt, in the event of any conflict of requirements the more stringent of the two standards should be employed.
