General Information

Abstract

ISO 3691-3:2016 gives safety requirements and the means for their verification, additional to those of ISO 3691‑1, for industrial trucks with a vertical, non-tilting mast:
a)    those trucks having an elevating operator position, and order‑picking trucks, as defined in ISO 5053‑1, where the elevating operator position and the load‑handling device lifts to a height of more than 1 200 mm above ground level;
b)    lateral- and front-stacking trucks, as defined in ISO 5053‑1, designed to travel with a load-handling device elevated more than 1 200 mm above ground level, with the load-handling device elevated, lowered or laterally displaced, laden or unladen, while the truck is travelling.
These trucks are designed to travel indoors on a smooth, level surface (e.g. concrete) and can be guided, unguided, or both, when in use; they are not intended to tow or push.
ISO 3691-3:2016 is not applicable to stacker trucks which handle two loads, one on the forks and the other on the support arms, this type of truck being covered by ISO 3691‑1.
It is not applicable to trucks with an elevating operator position up to and including 1 200 mm, or to trucks specifically designed to travel with an elevated load having a fork height up to and including 1 200 mm above ground level.
It is not applicable to low-level order pickers with elevating operator's position up to and including 1 200 mm lift height which can be equipped with an additional load lifting device having a maximum lift height of 1 800 mm from ground level.
ISO 3691-3:2016 deals with all significant hazards, hazardous situations, or hazardous events, as listed in Annex A, relevant to the applicable machines when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.
It does not establish requirements for hazards that can occur when using trucks on public roads or when operating in potentially explosive atmospheres.
Regional requirements, additional to the requirements given in this part of ISO 3691, are addressed in ISO/TS 3691‑7 and ISO/TS 3691‑8.

Overview

EN ISO 3691-3:2016 - Industrial trucks - Safety requirements and verification - Part 3 - specifies additional safety requirements and verification for industrial trucks that have a vertical, non‑tilting mast and either an elevating operator position or are specifically designed to travel with elevated loads. It complements ISO 3691‑1 and focuses on trucks where the operator position or load‑handling device exceeds 1 200 mm above ground. The standard applies to indoor trucks designed to travel on smooth, level surfaces (e.g., concrete) and covers guided or unguided operation. It does not cover road use, potentially explosive atmospheres, certain stacker trucks, or trucks with lift heights up to and including 1 200 mm.

Key Topics

  • Scope and hazards: Defines applicable machine types and lists significant hazards relevant to elevated travel (Annex A).
  • Operational modes: Safety measures for lateral‑ and front‑stacking trucks and order‑picking trucks when travelling with elevated loads.
  • Braking and travel speed: Requirements for brakes and reduced travel speeds when the operator or load is elevated, including differences for guided systems.
  • Controls and ergonomics: Requirements for operator controls, clearances and the elevating operator position to ensure safe use at height.
  • Lifting and lowering systems: Safe design, verification and emergency lowering provisions for elevated platforms and load‑handling devices.
  • Operator position & visibility: Design measures to protect an operator situated in an elevated position, including guarding and access.
  • Optical warning devices & stability: Requirements for visual warnings and stability verification when travelling with an elevated load.
  • Verification & documentation: Test methods, conformity verification, marking, installation information and instruction handbook requirements additional to ISO 3691‑1.

Applications

EN ISO 3691-3:2016 is used to:

  • Ensure design and safety compliance for trucks with elevating operator positions (order pickers) and trucks that travel with elevated loads.
  • Guide type testing and verification for manufacturers and conformity assessment bodies.
  • Define safe operating limits and instructions for warehouse fleet managers, safety officers and maintenance teams.
  • Support compliance with the EU Machinery Directive (2006/42/EC) when cited as the harmonized standard.

Who should use this standard

  • Truck manufacturers and design engineers
  • Certification and testing laboratories
  • Occupational health & safety professionals and fleet managers
  • Compliance engineers preparing technical documentation for CE marking

Related Standards

  • ISO 3691‑1 (general safety requirements for self‑propelled industrial trucks)
  • ISO 5053‑1 (definitions for order‑picking and stacking trucks)
  • ISO/TS 3691‑7 / 3691‑8 (regional requirements)
  • EN 16307‑3 (supplementary European requirements)

Using EN ISO 3691-3:2016 helps reduce risks associated with elevated operation of industrial trucks and provides clear verification steps for manufacturers and users to demonstrate safe design and use.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the

ISO 3691-3:2016(E)
Introduction
General
This part of ISO 3691 is a type-C standard as stated in ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations, or hazardous events
are covered are indicated in the Scope of this part of ISO 3691.
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 the requirements of this
type-C standard.
The ISO 3691 series covers safety requirements and their verification for industrial trucks as defined in
ISO 5053-1.
Structure
An important step forward in the work on the ISO 3691 series was the agreement to issue a new
structure of International Standards for industrial trucks having on one side, basic standards for all
kinds of trucks (see Foreword) and on the other side, independent standards to cover the respective
specific functions of industrial trucks, e.g. visibility, noise, vibration, electrical requirements, etc.
Assessment of hazards
The product needs to be designed in such a way that it is fit for its purpose or function and can be
adjusted and maintained without putting persons at risk when used under the conditions foreseen by
the manufacturer.
In order to properly design a product and to cover all specific safety requirements, the manufacturer
will have to identify the hazards that apply to his product and carry out a risk assessment. The
manufacturer will then need to design and construct the product taking this assessment into account.
The aim of this procedure is to eliminate the risk of accidents throughout the foreseeable lifetime of
the machinery, including the phases of assembling and dismantling where risks of accidents could also
arise from foreseeable abnormal situations.
In selecting the most appropriate methods, the manufacturer will need to apply the following principles
in the order given here:
a) eliminate or reduce risks as far as possible by design (inherently safe machinery design and
construction);
b) take the necessary protective measures in relation to risks that cannot be eliminated by design;
c) inform users of any shortcoming of the protective measures adopted;
d) indicate whether any particular training is required;
e) specify any need to provide personal protection equipment;
f) refer to the appropriate user’s document for proper operating instructions.
Industrial trucks need to be designed to prevent foreseeable misuse wherever possible, if such would
engender risk. In other cases, the manufacturer’s instructions will need to draw the user’s attention to
ways shown by experience in which the machinery ought not to be used.
This part of ISO 3691 does not repeat all the technical rules which are state-of-the-art and which are
applicable to the material used to construct the industrial truck. Reference will also need to be made to
ISO 12100.
ISO 3691-3:2016(E)
Legislative situation/Vienna Agreement
From the very beginning, the task of the working group was to revise ISO 3691:1980 and establish
worldwide basic standards to comply with the major legislative regulations in, for example, the EU,
Japan, Australia, and North America.
Every effort was made to develop a globally relevant International Standard. That goal was achieved
with most of the issues. For several potential problem areas, compromises were needed and will
be needed in the future. Where divergent regional requirements remain, these are addressed by
ISO/TS 3691-7 and ISO/TS 3691-8.
In order to ensure that the revised International Standard will be actively used in the ISO member
countries worldwide, procedures are necessary to replace the existing national standards and technical
regulations by the revised International Standard. In the European Community, ISO and the European
Committee for Standardization (CEN) agreed on technical co-operation under the Vienna Agreement,
with the aim of replacing European Standards (EN) by International Standards. Other countries are
asked to make similar agreements to ensure that their national standards and technical regulations are
replaced by this International Standard.
Only by these actions will there be the guarantee that products in accordance with International
Standards can be shipped worldwide freely without any technical barriers.

This part of ISO 3691 gives safety requirements and the means for their verification, additional to those
of ISO 3691-1, for industrial trucks with a vertical, non-tilting mast:
a) those trucks having an elevating operator position, and order-picking trucks, as defined in
ISO 5053-1, where the elevating operator position and the load-handling device lifts to a height of
more than 1 200 mm above ground level;
b) lateral- and front-stacking trucks, as defined in ISO 5053-1, designed to travel with a load-handling
device elevated more than 1 200 mm above ground level, with the load-handling device elevated,
lowered or laterally displaced, laden or unladen, while the truck is travelling.
These trucks are designed to travel indoors on a smooth, level surface (e.g. concrete) and can be guided,
unguided, or both, when in use; they are not intended to tow or push.
This part of ISO 3691 is not applicable to stacker trucks which handle two loads, one on the forks and
the other on the support arms, this type of truck being covered by ISO 3691-1.
It is not applicable to trucks with an elevating operator position up to and including 1 200 mm, or to
trucks specifically designed to travel with an elevated load having a fork height up to and including
1 200 mm above ground level.
It is not applicable to low-level order pickers with elevating operator’s position up to and including
1 200 mm lift height which can be equipped with an additional load lifting device having a maximum
lift height of 1 800 mm from gro
