What is Roll Over Protective Structure mean?
A rollover protection structure or rollover protection system (ROPS) ( or ) is a system or structure intended to protect equipment operators and motorists from injuries caused by vehicle overturns or rollovers. Like rollcages and rollbars in cars and trucks, a ROPS involves bars attached to the frame that maintain a space for the operator's body in the event of rollover.
Commonly found on heavy equipment (i.e. tractors), earth-moving machinery and UTVs used in construction, agriculture and mining, ROPS structures are defined by various regulatory agencies, including the US Occupational Safety and Health Administration (OSHA). The regulations include both a strength requirement as well as an energy absorption requirement of the structure. Some dump trucks add a protrusion to their boxes that cover the operator's compartment for ROPS purposes.
ROPS are commonly fitted to 4x4s, pickup trucks, earth moving equipment, soil compactors and utility vehicles used in the mining industry. Products such as this were developed out of necessity so employees travelling around or within mine sites were provided with extra protection in the event of a fleet vehicle rollover.
In the US, ROPS designs have to be certified by a professional engineer, who will normally require a destructive test. The structure will be tested at a reduced temperature (where the metal is more brittle), or fabricated from materials that have satisfactory low temperature performance. The International Organization for Standardization has guidelines for destructively testing ROPS structures on earthmoving machinery, excavators, forestry equipment and tractors. Theoretical performance analysis of major new design ROPS is not permitted as an alternative to physical testing.
