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 22915-5 was prepared by Technical Committee ISO/TC 110, Industrial trucks, Subcommittee SC 2, Safety of powered industrial trucks.

This edition cancels and replaces ISO 13563-1:2001 which has been technically revised.

ISO 22915 consists of the following parts, under the general title Industrial trucks — Verification of stability:

Part 1: General

Part 2: Counterbalanced trucks with mast

Part 3: Reach and straddle fork-lift trucks

Part 4: Pallet stackers, double stackers and order picking trucks up to and including 1200 mm lift height and double stackers

Part 5: Single side loading trucks

Part 7: Bi directional and multi directional trucks

Part 8: Additional stability test for trucks operating in special conditions of stacking with the mast tilted forward

Part 9: Counterbalanced trucks with mast handling freight containers of 6 m (20 ft) length and longer

Part 10: Additional stability test for trucks operating in special condition with the load substantially laterally displaced by powered devices.

Part 11: Industrial variable reach trucks

Part 12:Industrial variable reach trucks handling freight containers of 6 m length and longer

Introduction

See ISO 22915 part 1

DRAFT INTERNATIONAL STANDARD ISO/DIS 22915-5

© ISO 2008 – All rights reserved 1

1 Scope

This international standard specifies the tests to verify the stability of single side loading trucks with tiltable or non-tiltable mast or fork arms. It is applicable to trucks fitted with fork arms and/or attachments.

2 Normative references

The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

ISO 3691-1, Industrial trucks — Safety requirements and verification — Part 1: Self propelled industrial trucks, other than driverless and variable reach trucks and burden carriers

ISO 22915 -1, Industrial Trucks — Verification of stability: Part 1 –General

ISO 5053, Powered industrial trucks — Terminology

3 Terms and Definitions

For the purpose of this document, the terms and definitions given in ISO 5053 and ISO 22915-1 and the following apply.

3.1 Normal operating conditions when travelling

Travelling with the mast or fork arms tilted backwards if capable and the load retracted and in the lowered (travelling) position, or resting on the load carrying deck.

4 Test conditions

4.1 General

see ISO 22915-1

4.2 Position of the truck on the tilt table

The truck shall be positioned on the tilt table according to Figure 5 to Figure 19.

The indication of the articulating steer axle is the centre line of the axle. The allocation of the indication is defined in Figure 1.

Key A – A longitudinal centre plane of the truck B – B articulating steer axle

Figure 1 — Articulating steer axle, longitudinal centre plane

The truck shall be positioned on the tilt table with the line M - N parallel to the tilt axis, X - Y, of the tilt table.

Point N is the centre point of the area of contact between the tilt table surface and a non-articulating wheel or stabilizer pad. Point M is defined as follows.

a) For trucks with an articulating steer axle, B-B, designed to articulate approximately about the longitudinal centre plane of the truck, A-A, as shown in fig 1 : the projection onto the tilt table of the point of intersection of the longitudinal centre plane of the truck with the axis of this articulating axle (See figures 1 16 and 17)

b) For trucks without an articulating axle or with axle locks or stabilisers in use the centre point of the area of contact between the tilt table surface and another wheel or stabiliser pad (See figures 8,9,10,11,12,18 and 19).

When the truck rating is related to the use of stabilisers, suspension locks, etc., such devices shall be used during the tests. If the truck can be used without their engagement, an additional test shall be carried out in this condition.

4.3 Position of the load datum point

Tests 1 and 5 shall be conducted with the horizontal position of the load datum point, E, see figures 2, 3 and 4, unchanged when elevated from its lowered position.

By means of a plumb-line or other suitable equipment, set the mast vertical. Elevate the fork and the prescribed test load to approximately 300 mm above the tilt table. With the front face of the fork arm shank vertical, establish a point, E, on the fork or fork carrier having a fixed relationship to the centre of gravity of the test load, G. This point, E, shall be used to provide a reference datum, F, on the tilt table. When the mast is elevated, a new point, F1, on the tilt table may occur by the following adjustments this new point, F1, can be returned to the original location of F.

For trucks with tiltable masts, changes in the location of F1 shall be corrected by varying the tilt of the mast within the limits provided by the design of the truck.

Adjustments cannot be made on trucks having non-tiltable masts, or fork carrier. Mast retraction is not permitted.
