Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10896-7 was prepared by Technical Committee ISO/TC 110, Industrial trucks, Subcommittee SC 4,
Rough-terrain trucks.
ISO 10896 consists of the following parts, under the general title Rough-terrain trucks — Safety
requirements and verification:
— Part 1: Variable-reach trucks
— Part 2: Slewing variable-reach trucks
— Part 4: Additional requirements for variable-reach trucks handling freely-suspended loads
— Part 5: Interface between rough-terrain truck and integrated personnel work platform
— Part 6: Tilting operator’s cab
— Part 7: Longitudinal load moment systems
Safety requirements and verification for lorry-mounted trucks are to form the subject of future
ISO 20297-1.

Introduction
This International Standard is one of a set of standards produced by ISO/TC 110/SC 4 as part of its
program of work regarding 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.

DRAFT INTERNATIONAL STANDARD ISO/DIS 10896-7:2015(E)
Rough-terrain trucks — Safety requirements and
verification —
Part 7:
Longitudinal load moment systems
1 Scope
This part of ISO 10896 specifies design, safety and verification requirements for longitudinal load
moment systems which can be used on rough-terrain trucks (hereafter referred to as trucks). This
standard provides the requirements for both the longitudinal load moment indicator (hereafter
referred to as LLMI) and the longitudinal load moment control (hereafter referred 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:
1)
— lorry-mounted trucks as defined in ISO 20297-1 ;
2)
— slewing variable-reach trucks as defined 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 standard does not cover the risk due 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 whilst
the truck is travelling.
This document is not applicable to longitudinal load moment systems manufactured before the date of
its publication.

3  Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 12100, ISO 10896-1 and the
following apply.
3.1
longitudinal load moment
sum of the moments in the longitudinal plane forward of the tipping line (e.g., wheels, stabilisers)
produced by the load, the attachment and the lifting means of the truck
3.2
longitudinal load moment indicator

device that warns the operator of a change to the load handling geometry which would increase the
longitudinal load moment beyond pre-determined limit(s)
3.3
longitudinal load moment control

device that prevents the operator changing the load handling geometry in direction(s) which would
increase the longitudinal load moment beyond the allowable limit(s)
3.4
load handling geometry
relationship of points, lines and angles, described by the position of the load centre of gravity (the
po
