35、-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 machinery.

36、ed vBS ISO 2047412:2017BS ISO 2047412:2017Earth-moving machinery Safety Part 12: Requirements for cable excavators1 ScopeThis document gives the safety requirements specific to cable excavators as defined in ISO 6165. It is intended to be used in conjunction with ISO 20474-1, which specifies general

37、 safety requirements common to two or more earth-moving machine families. The specific requirements given in this document take precedence over the general requirements of ISO 20474-1.This document deals with all significant hazards, hazardous situations and events relevant to the earth-moving machi

38、nery within its scope (see ISO 20474-1:2017, Annex A) when used as intended or under conditions of misuse reasonably foreseeable by the manufacturer. It specifies the appropriate technical measures for eliminating or reducing risks arising from relevant hazards, hazardous situations or events during

39、 commissioning, operation and maintenance.It is applicable only to the machine itself if the cable excavator is intended for use in combination with other equipment or attachments such as drill rigs and those for pile driving or extracting and moving (e.g. rail-track, walking legs, pontoon, ship equ

40、ipment or stationary undercarriages). It does not deal with the specific hazards relevant to such additional equipment or attachments.This document is not applicable to machines manufactured before the date of its publication.2 Normative referencesThe following documents are referred to in the text
