Everything You Need to Know About EWP Testing

Home // Everything You Need to Know About EWP Testing

Elevated work platforms (EWP) such as scissor lifts, boom lifts and telehandlers are important pieces of machinery that must be tested regularly to ensure safety. In this blog, we’ll cover the five types of EWP testing that should feature in your schedule, as well as the specialised electrical testing that Mobile Test ‘n’ Cal regularly perform.

Who can test EWPs?

For an EWP test to be considered valid it must be completed by a competent person. The definition of a competent person depends on the inspection. For example, an employee with appropriate training may be the competent person for a pre-operation inspection, whereas a professionally trained engineer is the competent person for a major inspection. In all cases, a competent person refers to one with the appropriate training and skills to perform the task.

The five inspections

According to Australian Standard 2550.10-2006, there are five inspections that an EWP should regularly receive. Inspections will be detailed in a logbook and inspectors will regularly verify that the EWP has been maintained to the correct schedule.


  • Pre-operation inspections


To be completed by the machine operator at the commencement of each work shift. Should include visual and functional testing.


  • Routine inspection


To be completed quarterly or every 90 days. Control functions, emergency and safety devices will all be checked. Connection mechanisms and moving parts will be checked and maintained. 


  • Periodic inspection


The frequency will depend on the working environment and frequency of use however, every 12 months is typical. This is a detailed inspection which includes dismantling some parts of the machine. A written report will also be provided.


  • Enhanced periodic inspection


This inspection is carried out within 5-year intervals. It is meant to ensure all critical components of the machine are inspected and tested.


  • Major inspection


Beginning at the first 10 years of service for the machine, and continuing each 10 years thereafter, are major inspections. During this inspection, an EWP may be stripped down, cleaned, tested and maintained before being rebuilt.

Specialised testing of EWPs

If your EWP is more specialised than the standard machine, such as insulated, it may require further inspections. Mobile Test ‘n’ Cal have extensive experience in electrical testing of EWPs which ensures they are properly insulated. Tests that we perform include:

  • Periodic testing up to 210kV
  • Acceptance testing up to 300kV
  • Liner testing
  • Emergency Descent Device (EDD) inspections
  • Acoustic Emissions Testing (NZ only)
