Testing Services

QMW’s destructive testing capability and facility is one of the largest in the world and allows ROPS, FOPS & OPG testing for almost any type or size of OEM machine and/or bespoke OEM requirements, from 1.5-150 tonne.

Due to the structural integrity of the facility and the expertise of QMW staff, OEM chassis repairs and straightening can also be completed, significantly reducing operational downtime and repair costs.

QMW also undertake stability testing and load testing for attachments, loaders, handrails systems  engine and vehicle stands.





All ROPS, FOPS, TOPS and OPG products MUST be destructively tested and certified in accordance with the following standards:


  • Cabin and canopy ROPS to ISO 3471:2008
  • Cabin and canopy FOPS to ISO 3449:2005 (Level 1 or 2)
  • Excavator ROPS to ISO12117.2:2008
  • Excavator OPG to ISO10262:1998
  • Q~Transporter Series to ADR59/00 and ISO3471:2008


Note: AS2294.2, 3 & 4 withdrawn Dec 2008 and replaced by ISO3471, 3449 and 3164 Extract:  International Standard ISO 3471:2008(E) Earth-moving machinery – Roll-over protective structures – Laboratory tests and performance requirements.


1 Scope

This International Standard specifies performance requirements for metallic roll-over protective structures (ROPS) for earth-moving machinery, as well as a consistent and reproducible means of evaluating the compliance with these requirements by laboratory testing using static loading on a representative specimen.


5 Test method and test facilities

5.3 Test facilities

Fixtures shall be adequate to secure the representative specimen to bedplate and to apply the required lateral, vertical and longitudinal loads as determined by the formulae given in Table 1.

Annex B (informative)

Design changes, physical testing and alterations


B.3 Alternatives to physical testing

Theoretical performance analysis (i.e. FEA) of major new design ROPS is not permitted as an alternative to physical testing.



If you are in doubt on any aspect of standards, please contact a QMW specialist.
