(R) Operator Restraint System for Off-Road Work Machines
|Publication Date:||1 November 1997|
1. Scope - This SAE Standard provides performance and test requirements for operator restraint systems provided for off-road self-propelled work machines.
1.1 Purpose - This document applies to pelvic restraint systems (Type 1) for off-road, self-propelled work machines fitted with ROPS and commonly used in construction, earthmoving, forestry, and mining as referred to in SAE J1040 and industrial machines fitted with ROPS as referred to in SAE J1042.
1.2 Field of Application
1.2.1 This document applies to operator restraint systems that include seat systems of 70 kg mass or less.
1.2.2 For machines with seat systems of greater than 70 kg mass, such as those that include add-on control modules, it is necessary that the seat support be designed to withstand an additional force of ten times the mass of the seat system which exceeds the 70 kg mass. This force should be added to the 15 000 N test force described in 5.2.2.
