Current through Register Vol. 63, No. 12, December 1, 2024

Section 437-004-3650 - Roll-Over Protective Structures - Industrial Vehicles

(1) Application. There must be roll-over protective structures (ROPS) on certain industrial vehicles manufactured after July 1, 1969. ROPS requirements apply to the following types of industrial vehicles and equipment: Rubber-tired self-propelled scrapers; front-end loaders and dozers; wheel-type industrial tractors; crawler tractors; crawler-type loaders; and motor graders, with or without attachments. This requirement does not apply to sideboom pipe laying tractors, or other vehicles whose structure prevents overturn. 4/U, OAR 437-004-3600 covers ROPS for tractors used only in farming.

(2) ROPS - general requirements.

(a) Roll-over protective structures and their supporting attachments to industrial vehicles must be capable of supporting twice the weight of the vehicle, applied at the point of impact.

(b) The design objective for roll-over protective structures on industrial vehicles is to minimize the likelihood of a complete vehicle overturn, and to minimize the possibility of the operator being crushed.

(c) There must be a vertical clearance of at least 52 inches between the work deck and the ROPS canopy.

(d) Once removed, remount ROPS with bolts or welding or equal or better quality as required for the original mounting.

(3) Defects.

(a) Repairs to defective ROPS must be of equal quality or better materials and welding as on the original structure.

(b) Minimum performance criteria for roll-over protective structures for designated vehicles are in the following Society of Automotive Engineers (SAE) standards:

(A) Prime movers, for scrapers, water wagons, bottom dump wagons, side dump wagons, rear dump wagons, towed fifth wheel attachments. (SAE J1040, 1994)

(B) Wheeled front-end loaders and wheeled dozers. (SAE J1040, 1994)

(C) Track-type tractors and front-end loaders. (SAE J1040, 1994)

(D) Motor graders. (SAE J1040, 1994)

(E) Wheel-type agricultural and industrial tractors. (SAE J167, 1992)

(F) Falling object protective structures (FOPS). (SAE J231, May 1981)

(4) Identification of ROPS. Each ROPS must have the following information permanently affixed to the structure:

(a) Manufacturer or fabricator's name and address;

(b) ROPS model number, if any; and

(c) Machine make, model, or series number that the structure fits.

(5) Approved structures. Any machine in use, with roll-over protective structures, complies with these rules if it meets the roll-over protective structure requirements of the U. S. Army Corps of Engineers, or the Bureau of Reclamation of the U. S. Department of the Interior, in effect on April 5, 1972. The requirements in effect are:

(a)U. S. Army Corps of Engineers: General Safety Requirements, EM-385-1-1 (September 1996).

(b) Bureau of Reclamation, U. S. Department of the Interior: Safety and Health Regulations for Construction, Part II (September 1971).
