DANSK DSF/PREN ISO 3691-4 PDF

This part of EN ISO 3691 gives safety requirements and the means for their verification for driverless industrial trucks (hereafter referred to as trucks) and their systems. It is not applicable to trucks solely guided by mechanical means (rails, guides, etc.). For the purposes of this part of EN ISO 3691, a driverless industrial truck is a powered vehicle, including any trailer, which is designed to travel automatically and for which the safety of operation does not depend on an operator. Remote-controlled trucks are not considered to be driverless trucks. A truck's system comprises the control system, which may be part of the truck and/or separate from it, guidance means and power system. Specific requirements for power sources other than batteries (e.g hydrogen fuel cells, internal combustion engines) are not covered in this standard. Some trucks may also follow the requirements of EN ISO 3691-1. The condition of the operating area has a significant effect on the safe operation of the driverless industrial truck. The preparations of the operating area to eliminate the associated hazards are specified in Annex A. This part of EN ISO 3691 deals with all significant hazards, hazardous situations or hazardous events, as listed in Annex B, with the exception of the following, 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 -≥during operation in severe conditions (e.g. extreme climates, freezer applications, strong magnetic fields), -≥during operation in environments subject to special rules (e.g. potentially explosive atmospheres), -≥during the transportation of passengers other than a trained operator, -≥when handling loads the nature of which could lead to dangerous situations (e.g. molten metals, acids/bases, radiating materials), -≥from parts of trucks requiring manual intervention during operation, -≥from trucks intended to operate in areas open to persons unaware of the hazards. Regional requirements, additional to the requirements given in this part of EN ISO 3691, are addressed in ISO/TS 3691-7 and ISO/TS 3691-8.
