Industrial trucks - Safety requirements and verification - Part 4: Driverless industrial trucks and their systems

This document specifies safety requirements and the means for their verification for driverless industrial trucks (hereafter referred to as trucks) and their systems.*Examples of driverless industrial trucks (trucks as defined in ISO 5053 1:2020) include: automated guided vehicle”, autonomous mobile robot”, bots”, automated guided cart”, tunnel tugger”, under cart”, etc.*This document is also applicable to driverless industrial trucks which are provided with:*–    automatic modes which either require operators’ action(s) to initiate or enable such automatic operations;*–    the capability to transport one or more riders (which are neither considered as drivers nor as operators);*–    additional manual modes which allow operators to operate the truck manually; or*–    a maintenance mode which allows manual operation of truck functions for maintenance reasons.*This document is not applicable to trucks solely guided by mechanical means (rails, guides, etc.) or to remotely-controlled trucks, which are not considered to be driverless trucks.*For the purposes of this document, a driverless industrial truck is a powered truck, which is designed to operate automatically. A driverless truck system comprises the control system, which can be part of the truck and/or separate from it, guidance means and power system. Requirements for power sources are not covered in this document.*The condition of the operating zone has a significant effect on the safe operation of the driverless industrial truck. The preparations of the operating zone to eliminate the associated hazards are specified in Annex A.*This document is applicable to all significant hazards, hazardous situations or hazardous events during all phases of the life of the truck (ISO 12100:2010, 5.4), as listed in Annex B, relevant to the applicable machines when it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.*In particular, this document does not apply to significant hazards related to:*–    noise;*–    vibrations;*–    ionising and non-ionising radiation;*–    laser radiation;*–    sales literature (commercial documents);*–    declaration of vibrations transmitted by mobile machinery.*It does not apply to additional hazards that can occur:*–    during operation in severe conditions (e.g. extreme climates, freezer applications, strong magnetic fields);*–    during operation in nuclear environments;*–    from trucks intended to operate in public zones (see in particular ISO 13482:2014);*–    during operation on a public road;*–    during operation in potentially explosive environments;*–    during operation in military applications;*–    during operation with specific hygienic requirements;*–    during operation in ionizing radiation environments;*–    during the transportation of (a) person(s) other than (the) intended rider(s);*–    when handling loads the nature of which can lead to dangerous situations (e.g. molten metals, acids/bases, radiating materials);*–    for rider positions with elevation function higher than 1 200 mm from the floor/ground to the platform floor.*This document does not contain safety requirements for trailer(s) being towed behind a truck.*This document does not contain safety requirements for elevated operator trucks.*This document does not apply to trucks manufactured before the date of its publication.
