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 Standard is one of a series of CSA Standards on roll-over and tip-over protection for mobile construction, industrial, mining, forestry, and agricultural machinery. This series is divided into the following Standards, with additional Standards to be added as they are developed:
(a) CSA B352.0, Rollover Protective Structures (ROPS) for Agricultural, Construction, Earthmoving, Forestry, Industrial, and Mining Machines — Part 1: General Requirements;
(b) CSA B352.1, Rollover Protective Structures (ROPS) for Agricultural, Construction, Earthmoving, Forestry, Industrial, and Mining Machines — Part 2: Testing Requirements for ROPS on Agricultural Tractors;
(c) CSA B352.2, Rollover Protective Structures (ROPS) for Agricultural, Construction, Earthmoving, Forestry, Industrial, and Mining Machines — Part 3: Testing Requirements for ROPS on Construction, Earthmoving, Forestry, Industrial, and Mining Machines;
(d) CSA M3463, Wheeled tractors for agriculture and forestry — Protective structures — Dynamic test method and acceptance conditions;
(e) M3471, Earth-moving machinery — Roll-over protective structures — Laboratory tests and performance requirements;
(f) M5700, Wheeled tractors for agriculture and forestry — Protective structures — Static test method and acceptance conditions;
(g) M8082, Self-propelled machinery for forestry — Roll-over protective structures — Laboratory tests and performance requirements; and
(h) M12117, Earth-moving machinery — Tip-over protection structures (TOPS) for compact excavators — Laboratory tests and performance requirements.
Adoption of these ISO Standards on ROPS and TOPS, along with Standards such as ISO 3776 on operator restraint systems, will aid in the safe design of mobile construction, industrial, mining, forestry, and agricultural machinery across North America.
This Standard was reviewed for Canadian adoption by the CSA Technical Committee on Roll-over Protective Structures, under the jurisdiction of the Standards Steering Committee on Occupational Health and Safety and has been formally approved by the Technical Committee. A list of the members of the Technical Committee is available upon request. This Standard has been approved as a National Standard of Canada by the Standards Council of Canada.
Scope
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.
