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:

Part 6: Requirements for dump trucks

1 Scope

This document specifies wheeled and tracked tippers (including seat-operated small tippers or stand-operated tippers) as defined by ISO 6165

Safety requirements for small dump trucks), not applicable to road dump trucks; specifies the conditions for 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

Specifies technical measures to eliminate or reduce the risks arising from major hazards, hazardous states or hazardous events during 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:

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