GB/T 25684.13-2021Earth-moving machinery - Safety - Part 13: Requirements for rollers (English PDF)

1 Scope

This document specifies the safety requirements for road rollers as defined by ISO 6165; specifies the use of earth-moving machinery in

All major hazards, hazardous states and hazardous events related to it when applied under conditions of misoperation (see GB/T 25684:1-2021

Appendix A); and specifies techniques for eliminating or reducing the risks arising from significant hazards, hazardous states or hazardous events in use, operation and maintenance measure:
