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 standard that guides my country's earth-moving machinery products to meet relevant safety requirements:
allow: GB/T 25684 aims to establish general safety requirements applicable to earth-moving machinery products and special safety requirements for specific machine families
It is proposed to consist 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 Clause:
--- Part 4: Requirements for backhoe loaders: The purpose is to propose a product that meets the unique characteristics of backhoe loader products:
Point-specific security requirements clause:
--- Part 5: Requirements for hydraulic excavators: The purpose is to put forward the unique characteristics of hydraulic excavator products that meet the characteristics of their own products:
Point-specific security requirements clause:
--- Part 6: Requirements for dump trucks: The purpose is to propose specific products that meet the unique characteristics of dump truck products:
Security Requirements Clause:
--- Part 7: Requirements for scrapers: The purpose is to propose specific products that meet the characteristics of their own products according to the unique characteristics of scraper products:
Security Requirements Clause:
--- Part 8: Motor grader requirements: The purpose is to propose specific products that meet the unique characteristics of motor graders:
Security Requirements Clause:
--- Part 9: Requirements for pipelayers: The purpose is to propose specific products that meet the unique characteristics of the pipelayer products:
Security Requirements Clause:
--- Part 10: Requirements for trenchers: The purpose is to propose special features that conform to the characteristics of the trencher products according to the unique characteristics of the trencher 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 3: Requirements for loaders
1 Scope
This document specifies the safety requirements for loaders as defined by ISO 6165; specifies requirements for earth-moving machinery for
All major hazards, hazardous states and hazardous events related to it when applied under conditions of misoperation (see the appendix of GB/T 25684:
Record A); and specifies techniques for eliminating or reducing risks arising from significant hazards, hazardous states or hazardous events in use, operation and maintenance
measure:
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:
