Earthmoving Machinery - Falling-Object Protective Structures - Laboratory
Tests and Performance Requirements
Description / Abstract:
0.1 Scope - This SAE Standard applies to operator-controlled machines as described in ISO 3471 and to the following off-road work machines of mass greater than 700 kg that are commonly used in earthmoving, construction, logging, and mining applications as identified in SAE J1116 JUN86 and designed for an on-board, seated operator:
a. Crawler tractors and loaders (see SAE J1057 SEP88 Sections 3.1 and 7.1 and SAE J727 JAN86 for description and nomenclature).
b. Graders (see SAE J1057 SEP88 Section 6 and SAE J870 JUL84 for description and nomenclature).
c. Wheel loaders, wheel tractors, and their modifications used for rolling or compacting, dozer equipped wheel tractors, wheel log skidders, skid steer loaders, and backhoe loaders (see SAE J1057 SEP88 Sections 3.2, 7.2, and 9 for description and nomenclature.)
d. Wheel industrial tractors (see SAE J1092 JUN86 for description and nomenclature).
e. Tractor portion of semi-mounted scrapers, water wagons, articulated steer dumpers, bottom dump wagons, side dump wagons, rear dump wagons, and towed fifth wheel attachments (see SAE J1057 SEP88 Sections 4.1.1.4, 4.1.2, 4.2.1.1, 4.3.1.2, 4.3.1.3, 4.3.2, and 5 and SAE J869 JUL90 and SAE J728 JUL90 for description and nomenclature).
f. Rollers and compactors (see SAE J1017 JAN86 for description and nomenclature).
g. Rigid frame dumpers with full mounted bodies (see SAE J1057 SEP88 Sections 4.1.1.1, 4.1.1.2, 4.1.1.3, 4.1.1.5, and 4.3.1.1, and SAE J1016 JUL90 for description and nomenclature).
1. Scope
1.1 This SAE Standard specifies:
a. The laboratory tests for measurement of structural characteristics, and
b. The performance requirements in a representative test,
of a falling-object protective structure (FOPS).
1.2 The laboratory tests are a means of testing the characteristics of the structures used to protect the operator from localized impact penetration and, indirectly, of the load-capacity of the supporting structure to resist impact loading.
1.3 This document establishes a consistent, repeatable means of evaluating characteristics of FOPS under loading and prescribes performance requirements for these structures under such loading in a representative test.
1.4 This document applies to the following types of operator-controlled machines, regardless of the type of steering system used, as defined in ISO 6165:
a. Crawler loaders, wheel loaders, and backhoe loaders
b. Crawler tractors and wheel tractors
c. Graders
d. Tractor-scrapers
1.5 This document does not apply to:
a. Self-propelled compactors
b. Drills
c. Paving machines
d. Machines having a power rating less than 15 kW (20 hp)
e. Belt loaders
f. Excavators
g. Cranes
h. Drag lines
