This SAE Recommended Practice applies only to excavators, as defined in ISO 6165, working above ground, near an excavated or free-standing bank or mine face which is higher than the top of the cab, or in demolition applications of freestanding buildings or objects higher than the top of the cab.

This SAE Recommended Practice applies only to excavators, as defined in ISO 6165, working above ground, near an excavated or free-standing bank or mine face which is higher than the top of the cab, or in demolition applications of free standing buildings or objects higher than the top of the cab.

The purpose of this SAE Information Report is to provide concepts for rational selection and application of materials for Rollover Protective Structures (ROPS) and Falling Object Protective Structures (FOPS) and to provide information about the properties that should be considered in selecting and utilizing material in protective structures. While other materials could conceivably be used successfully, this report is limited to a consideration of steel with discussion on its mechanical properties and processing characteristics. Emphasis is placed on the toughness aspect (ability to resist brittle fracture) as this property is of paramount importance to structure integrity. It is emphasized that specific values for material properties have relevance to performance only in conjunction with specific design considerations such as structure size or weld joint detail and location.

This Recommended Practice applies only to machines covered by SAE J1040c (ROPS). The evaluations are for resistance to localized penetration. The performance requirements, of a representative specimen within the manufacturer’s specifications, are based on the performance of experience proven structures under the laboratory evaluation procedure. It is intended that all portions of this Recommended Practice shall be reviewed and revised as additional knowledge of FOPS performance becomes available.
