Material, equipment, and tiedown means adequate to insure that the ROPS and its vehicle frame absorb the applied energy.
Recommended, but not mandatory, types of test setups are illustrated in Figure W-1 for all types of equipment to which this section applies; and in Figure W-2 for rubber-tired self-propelled scrapers; Figure W-3 for rubber-tired front-end loaders, rubber-tired dozers, and motor graders; and Figure W-4 for crawler tractors and crawler-type loaders.
Equipment necessary to measure and apply loads to the ROPS. Adequate means to measure deflections and lengths should also be provided.
Table W-1 contains a listing of the required apparatus for all types of equipment described in paragraph (a) of this section.
|Means to measure||Accuracy|
|Deflection of ROPS, inches||±5% of deflection measured.|
|Vehicle weight, pounds||±5% of the weight measured.|
|Force applied to frame, pound||±5% of force measured.|
|Dimensions of critical zone, inches.||±5% in.|
