Product Code:SAE J2267
Title:Minimum Performance Criteria for Operator Front Protective Structure (OFPS) for Certain Equipment
Issuing Committee:Mtc4, Forestry And Logging Equipment
Scope:This SAE standard applies to all forestry machines exposed to the hazard of objects penetrating the front of the operator station (other than the roof). This would include:Front guards for yarders with cabs mounted next to the tower;Front guards for forestry machines capable of handling material in front of and above the deflection limiting volume (DLV); such as knuckle boom log loaders and swing to tree feller bunchers; but excluding rubber-tired or tracked front-end loaders when equipped with buckets or forks with hold down grapple arm(s); and excluding forwarders and clambunk skidders fitted with load bunk headboards meeting the requirements of ISO 11850.
