Introduction
This document is a Type C standard defined by ISO 12100:
The scope of this document describes the machinery involved and the scope of the hazards, hazardous states or hazardous events involved:
Since the design and manufacture of the machine follow the requirements of Class C standards, when the requirements of Class C standards are different from those of Class A or Class B standards
At the same time, the requirements of Class C standards take precedence over other standards:
GB/T 25684 "Earth-moving Machinery Safety" is a basic and universal guideline for guiding my country's earth-moving machinery products to meet relevant safety requirements:
standard: GB/T 25684 aims to establish general safety requirements applicable to earth-moving machinery products and special safety requirements for specific machine families
requirements, it is proposed to be composed of 14 parts:
--- Part 1: General requirements: The purpose is to establish general safety requirements applicable to all machine types in the earthmoving machinery industry:
The foundational standard for a full range of standards:
--- Part 2: Requirements for bulldozers: The purpose is to propose specific products that meet the unique characteristics of bulldozer products:
Security Requirements Clause:
--- Part 3: Requirements for loaders: The purpose is to propose specific products that meet the characteristics of their own products according to the unique characteristics of loader products:

Security requirements clauses:
--- Part 11: Requirements for backfill compactors: The purpose is to propose products that meet the unique characteristics of backfill compactor products:
Features specific security requirements clause:
--- Part 12: Requirements for mechanical excavators: The purpose is to propose products that meet the unique characteristics of mechanical excavators:
Features specific security requirements clause:
--- Part 13: Requirements for road rollers: The purpose is to propose special characteristics that meet the characteristics of the rollers according to the unique characteristics of the road roller products:
Security requirements clauses:
--- Part 14: Requirements for small implement carriers: The purpose is to put forward a proposal to meet the unique characteristics of small implement carrying machine products:
Specific safety requirements clauses for their own product features:
The safety requirements of Part 2 to Part 14 are used in conjunction with the general requirements of Part 1 to better meet the use requirements:
Earthmoving Machinery Safety
Part 2: Requirements for bulldozers
1 Scope
This document specifies the safety requirements for wheeled and tracked bulldozers and their rear-mounted winches as defined in ISO 6165; specifies the earth-moving machinery
All significant hazards, hazardous states and hazardous events associated with the manufacturer's intended use or under conditions of reasonable mishandling foreseen
(See Appendix A of GB/T 25684:1-2021); and specifies the elimination or reduction of major hazards, dangerous states or
Technical measures for risks arising from hazardous events:
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:
This document does not apply to machines manufactured prior to the implementation of this document:
