European foreword
This document (prEN 1459-1:2026) has been prepared by Technical Committee CEN/TC 150 “Industrial
Trucks - Safety”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1459-1:2025.
In comparison with the previous edition, the following technical modifications have been made:
— addition of requirements for the operator restraint;
— addition of requirements for protection against corruption;
— additional requirements for safety functions;
— addition of requirements for visibility at height;
— addition of requirements for software;
— addition of requirements for towing.
EN 1459 consists of the following parts, under the general title Rough-terrain trucks — Safety
requirements and verification:
— Part 1: Variable-reach trucks
— Part 3: Interface between the variable-reach truck and the work platform
— Part 4: Additional requirements for variable-reach trucks handling suspended loads
— Part 5: Attachment interface
— Part 6: Application of EN ISO 13849-1 to slewing and non-slewing variable-reach rough-terrain truck
(technical report)
— Part 7: Electrification
— Part 9: Variable-reach trucks equipped with work platforms having a frontguard that can be opened
This document has been prepared under a standardization request given to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
Introduction
This document covers general safety requirements and the means for verification of these requirements
for rough-terrain variable-reach trucks.
All quantities are in SI units, and this includes metric units.
This document is a type C standard as stated in EN ISO 12100:2010.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B
standards, the provisions of this type C standard take precedence over the provisions of the other
standards, for machines that have been designed and built according to the provisions of this type C
standard.
1 Scope
This document specifies the safety requirements of self-propelled rough-terrain variable-reach trucks
(hereafter referred to as trucks), intended to handle loads, equipped with a telescopic lifting means
(pivoted boom), on which a load handling device (e.g. carriage and fork arms) is fitted.
For the purpose of this document, rough-terrain variable-reach trucks are designed to transport, lift and
place loads and can be driven on unimproved terrain.
Fork arms are considered to be part of the truck. Trucks can also be equipped with a variety of
attachments (e.g. bale spikes, mowers, sweepers).
This document deals with all the significant hazards, hazardous situations and events relevant to the
trucks when they are used as intended and under conditions of misuse which are reasonably foreseeable
by the manufacturer (see Annex A).
This document does not apply to:
— slewing rough-terrain variable-reach trucks covered by EN 1459-2:2015+A1:2018;
— rough-terrain variable-reach tractors covered by prEN 17968:2025;
— industrial variable reach trucks covered by EN ISO 3691-2:2023;
— lorry-mounted variable-reach trucks covered by ISO 20297-1:2017;
— variable-reach trucks fitted with tilting or elevating operator position;
— mobile cranes covered by EN 13000:2010+A1:2014;
— machines designed primarily for earth moving, even if their buckets and blades are replaced with
forks (see EN 474 series);
— trucks designed primarily with variable length load suspension elements (e.g. chain, ropes) from
which the load may swing freely in all directions;
— trucks designed primarily for container handling;
— trucks on tracks;
— trucks with articulated chassis;
— attachments.
This document does not cover sales literature.
This document does not address hazards linked to:
— operation of the truck from a position other than the normal operating position;
— operation of the truck by a remote control;
— gas power systems;
— gasoline engine systems;
— autonomous functions;
— self-evolving behaviour;
— hybrid or battery power systems having a voltage greater than 32 V DC or 21 V AC r.m.s.
NOTE EN 1459-7:2026 deals with hybrid and battery power systems having a voltage greater than 32 V DC or
21 V AC r.m.s.
This document does not address hazards which may occur:
a) when handling suspended loads which may swing freely (additional requirements are given in
EN 1459-4:2020+A1:2025);
b) when using trucks on public roads;
c) when operating in potentially explosive atmospheres (additional requirements are given in
EN 1755:2024);
d) when operating underground;
e) when fitted with a personnel work platform (additional requirements are given in EN 1459-3:2015
and EN 1459-9:2021);
f) when using system capable of controlling the speed of the truck as set by the operator (cruise-
control).
This document is not applicable to trucks manufactured before the date of its publication.

— lift height;
— reach of the boom;
— standard load centre distance;
— load handling device (fork arms or attachment fitted);

capable of lifting and transporting on fork arms in normal conditions with the boom fully retracted
3.6
reach
d
distance between two vertical parallel planes, one plane tangent to the front of the outside diameter of
the front tyres, the other plane described by the vertical projection of the centre-of-gravity of the load to
the ground
Note 1 to entry: The centre-of-gravity of the load (G) is defined in Table 1.
Note 2 to entry: See Figure 2 for examples of reach.
Note 3 to entry: For practical matters, d can be measured referring to point g, being g the vertical projection of the
