CROPS Testing Information, Massey Ferguson 135 Series
Static testing of a fully assembled NIOSH CROPS was performed at the NIOSH Division of Safety Research laboratories in Morgantown, West Virginia, and in accordance with testing criteria outlined in SAE J�194. The main purpose of the static laboratory testing was to simulate field upset in a controlled and repeatable environment (SAE J�194). The static loading sequence consisted of four tests: (1) longitudinal loading, (�) 1st vertical crush loading, (3) transverse loading, and (4) �nd vertical crush loading. During any of the four phases of static testing, the CROPS cannot be altered (e.g., bolts tightened, material repairs) and cannot touch or enter the operator clearance zone.
During the static laboratory testing, the loads were applied slowly over time, with the applied force and corresponding displacement collected. From these measurements, the energy absorbed by the CROPS was calculated (see graphs).
The photos show the condition of the tested CROPS at the beginning and the end of each of the four static tests.
