CSA Preface

This is the first edition of CAN/CSA-M3471, Earth-moving machinery - Roll-over protective structures - Laboratory tests and performance requirements, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard (first edition, 1994-02-01), including Amendment 1:1997 and Technical Corrigendum 1:2000.


This International Standard establishes a consistent and reproducible means of evaluating the load carrying characteristics of Roll-Over Protective Structures (ROPS) under static loading, and prescribes performance requirements for a representative specimen under such loading.

It applies to the following seated design operator controlled machines as defined in IS0 6165:

- crawler tractors and loaders;

- graders;

- wheeled loaders and wheeled tractors and their modified versions used for rolling or compacting, dozer-equipped wheeled tractors, skid-steer loaders and backhoe loaders;

- wheeled industrial tractors;

- the tractor portion (prime mover), of tractor scrapers, water wagons, articulated steer dumpers, bottom-dump wagons, side-dump wagons, rear-dump wagons and towed fifth-wheel attachments;

- rollers and compactors;

- rigid frame dumpers.
