Landmaster has met the ANSI/ROHVA 1-2016: ROPS requirements. We have also met the requirements for ISO 3471:2008 Earth-moving machinery — Roll-Over Protection System (ROPS) — Laboratory tests and performance requirements.
Both are requirements for a standard level of safety expected of manufacturers for drivers and passengers in the event of rolling their vehicle. Some metrics they are based on include heavy loads from various directions and minimum/maximum deflection.
ISO 3471:2008 specifies performance requirements for metallic ROPS for earth-moving machinery, as well as a consistent and reproducible means of evaluating compliance with these requirements by laboratory testing using static loading on a representative specimen.
ISO 3471:2008 applies to ROPS intended for the following mobile machines with a seated operator as defined in ISO 6165 and with a mass greater than or equal to 1,540 lbs. (700 kg): dozer; loader; backhoe loader; dumper; pipelayer; tractor section (prime mover) of a combination machine (e.g., tractor scraper, articulated frame dumper); grader; landfill compactor; roller; trencher.
