Rough-terrain trucks — Safety requirements and verification — Part 1: Variable-reach trucks

This document specifies general safety requirements for non-slewing, rough-terrain variable-reach trucks (referred to as trucks), with rigid chassis and equipped with a telescopic lifting means (pivoting boom) on which a load-handling device such as a carriage with fork arms is typically fitted. Fork arms and other integrated attachments are considered to be parts of the truck.

NOTE These trucks are also known as telehandlers, or telescopic handlers.

For the purpose of this document, trucks are designed to transport, lift and place loads and can be driven on unimproved terrain. They can also be equipped with a variety of attachments or interchangeable equipment (e.g. fork arms, bale spikes, mowers, sweepers) which can be both load-carrying and non-load-carrying.

Other standards, in addition to the relevant provisions of this document, can apply to the attachments.

This document is not applicable to the following:

a) industrial variable-reach trucks covered by ISO 3691-2;

b) machines designed primarily for earth moving, such as loaders, even if their buckets are replaced by fork arms (see ISO 20474-3);

c) trucks with articulated chassis;

d) machines designed primarily with v
