32、 the Scope of this document.When requirements of this type-C standard are different from those which are stated in type-A or B standards, the requirements of this type-C standard take precedence over the requirements of the other standards for machines that have been designed and built according to

33、the requirements of this type-C standard.ISO 20474 provides acceptable safety requirements for earth-moving machinery. This standard does not necessarily provide requirements to meet all national and regional regulatory provisions, e.g. Japan does not allow object handling with earth-moving machiner

ISO 2017 All rights reserved vBS ISO 204746:2017BS ISO 204746:2017Earth-moving machinery Safety Part 6: Requirements for dumpers1 ScopeThis document gives the safety requirements specific to wheeled and crawler dumpers as defined in ISO 6165, including compact dumpers with seated or standing oper

35、ator. It is not applicable to dumpers primarily designed for use on public roads. It is intended to be used in conjunction with ISO 20474-1, which specifies general safety requirements common to two or more earth-moving machine families. The specific requirements given in this document take preceden

36、ce over the general requirements of ISO 20474-1.This document deals with all significant hazards, hazardous situations and events relevant to the earth-moving machinery within its scope (see ISO 20474-1:2017, Annex A) when used as intended or under conditions of misuse reasonably foreseeable by the

37、manufacturer. It specifies the appropriate technical measures for eliminating or reducing risks arising from relevant hazards, hazardous situations or events during commissioning, operation and maintenance.This document is not applicable to machines manufactured before the date of its publication.2
