1 Scope

This document specifies the safety requirements for mechanical excavators and specifies the conditions for reasonable misoperation of earth-moving machinery in the manufacturer's designated purpose or foreseen:

When applied under conditions, all major hazards, hazardous states and hazardous events related to it (see Appendix A of GB/T 25684:1-2021); and regulations

It defines technical measures to eliminate or reduce the risks caused by major hazards, dangerous states or dangerous events in use, operation and maintenance:

This document is used in conjunction with GB/T 25684:1 (specifying general safety requirements for two or more families of earth-moving machinery): of this document

Specific requirements take precedence over the general requirements of GB/T 25684:1:

If it is expected to work with other work equipment or attachments such as drilling rigs, piling and piling equipment and mobile equipment (such as rails, walking legs, pontoons and ships) or fixed chassis, this document is also applicable to this type of mechanical excavator, chassis and superstructure, this document does not

Specific hazards are specified in relation to the above-mentioned additional equipment or attachments:

This document applies to mechanical excavators as defined by ISO 6165:

This document does not apply to machines manufactured prior to the implementation of this document:
