18.B.13 Rollover Protective Structures (ROPS).

2. ROPS are not required on:
• (1) Trucks designed for hauling on public highways;
• (2) Crane-mounted dragline backhoes;
• (3) Sections of rollers and compactors of the tandem steel-wheeled and self-propelled pneumatic-tired type that do not have an operator's station;
• (4) Self-propelled, rubber-tired lawn and garden tractors and side-boom pipe laying tractors operated solely on flat terrain (maximum 10º slope; 20º slope permitted when off- loading from a truck) not exposed to rollover hazards; and
• (5) Cranes, draglines, or equipment on which the operator's cab and boom rotate as a unit.
3. ROPS may be removed from certain types of equipment when the work cannot be performed with the ROPS in place and when ROPS removal is justified and delineated in an AHA and accepted in writing by the GDA.
4. The operating authority must furnish proof from the manufacturer or certification from a licensed engineer that the ROPS complies with applicable SAE Standards (i.e., J167, J1040, J1042, J1084, and J1194).
5. ROPS must also be acceptable if they meet the criteria of any State that has a Department of Labor-approved OSHA program or meets Water and Power Resources Service requirements.
6. The following information permanently affixed to the ROPS is acceptable in lieu of a written certification:
• (1) Manufacturer's or fabricator's name and address;
• (2) ROPS model number, if any; and
• (3) Machine make, model, or series number that the structure is designed to fit.
7. Field welding on ROPS must be performed by welders who are certified, per Section 10.A.07.

18.B.14 All points requiring lubrication during operation must have fittings so located or guarded to be accessible without hazardous exposure. > See also Section 12.

18.B.15 All machinery or equipment and material hoists operating on rails, tracks, or trolleys must have positive stops or limiting devices either on the equipment, rails, tracks, or trolleys to prevent overrunning safe limits.

18.B.16 Under the following circumstances, long-bed end-dump trailers used in off-road hauling should be equipped with a rollover warning device. The device should have a continuous monitoring display at the operator station to give the operator a quick and easily read indicator and audible warning of an unsafe condition:

1. The material being dumped is subject to being stuck or caught in the trailer rather than exiting the bed freely, and
2. The dumpsite cannot be maintained in a nominally level condition (lateral slope less than 1º - 2º).
