Earthmoving Machinery Safety
Part 1: General Requirements
1 Scope
This document specifies the general safety requirements for earth-moving machinery as defined by ISO 6165, which are required for two or more families of earth-moving machinery:
shared: Also suitable for machine attachments and primarily designed for use in digging, loading, transporting, drilling, paving, compacting or trenching soil, rock
Work devices for stone and other materials:
This document specifies all the heavy lifting of earth-moving machinery when it is used for the purpose specified by the manufacturer and under conditions of reasonable misoperation predicted by the manufacturer:
Major hazards, dangerous states and hazardous events (see Appendix A); and specifies the elimination or reduction of major hazards, dangerous states in use, operation and maintenance
technical measures for risks arising from a state or hazardous event:
This document maintains association with other parts of GB/T 25684, which give specific machine family details in other parts of GB/T 25684
Provisions: These specific requirements take precedence over the requirements for machinery in this document: For multifunctional machines, in all parts of GB/T 25684
Requirements covering such machine functions and applications apply:
Example: For small loaders with trenching function, the relevant requirements of GB/T 25684:1, GB/T 25684:3 and GB/T 25684:10 apply:
ISO 17757 covers specific requirements related to automatic machines:
