19、standardization of terminology, general safety, performance and user requirements for rough-terrain trucks (hereafter also referred to as trucks).This document is a type-C standard as stated in ISO 12100.The machinery concerned and the extent to which hazards, hazardous situations or hazardous event
20、s are covered are indicated in 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 d
21、esigned and built according to the requirements of this type-C standard. ISO 2016 All rights reserved vBS ISO 10896-7:2016BS ISO 10896-7:2016Rough-terrain trucks Safety requirements and verification Part 7: Longitudinal load moment systems1 ScopeThis document specifies design, safety and verificatio
22、n requirements for longitudinal load moment systems which can be used on rough-terrain trucks (hereafter referred to as trucks). This document provides requirements for both the longitudinal load moment indicator (hereafter referred to as LLMI) and the longitudinal load moment control (hereafter ref
23、erred to as LLMC) used on rough-terrain trucks, defined in ISO 10896-1, in a stationary position performing loading or placing functions on consolidated, stable and level ground.It is not applicable to the following: lorry-mounted trucks as defined in ISO 20297-1; slewing variable-reach trucks as de
24、fined in ISO 10896-2.This document deals with significant hazards, hazardous situations or hazardous events relevant to longitudinal load moment systems when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.This document does not cover the risk due
25、 to lateral instability or instability due to the travelling of the truck. The longitudinal load moment system is not intended for warning of the overturning risk while the truck is travelling.This document is not applicable to longitudinal load moment systems manufactured before the date of its pub
