Certification to AS 4991

Think Structural caters to the needs of clients across a variety of industries who have one thing in common – their need for certification of lifting equipment.

Section 12 of Australian Standard 4991-2004 Lifting Devices, identifies two appropriate methods to certify/verify Lifting Equipment:

  • Physical testing to up to two times the required working load limit (WLL)
  • Third party engineering analysis

Think Structural offers clients a comprehensive certification process service for both in-house and field testing. We can perform analysis and verification of designs, as well as specifying any additional procedures, such as NDT, that may be required.

 35t A-Frame

A client within the oil and gas sector required a 35t capacity A-frame to safely lift a piece of equipment offshore. Think was engaged to perform structural assessment and design verification of the proposed A-frame. Once completed the A-frame beam was proof tested and witnessed by a certified Engineer.

Our experienced team are led by certified Engineers who verify all work. Our Engineers meet the stringent qualification and experience requirements for registration with:

  • RPEQ – Board of Professional Engineers of Queensland
  • NER – National Engineering Register
  • CPEng – Engineers Australia

Your company can be assured that your lifting equipment will be assessed by Think’s team of experts to ensure that it meets the requirements of the standard.
