Industrial trucks - Safety requirements and verification - Part 1: Self-propelled industrial trucks, other than variable-reach trucks, towing tractors and burden-carrier trucks (ISO/FDIS 3691-1:2026); German version FprEN ISO 3691-1:2026
Abstract
This document specifies safety requirements and the means for their verification for the following types of self-propelled industrial trucks (hereafter referred to as "trucks") as defined in ISO 5053-1:2020: a) counterbalance lift trucks; b) reach trucks with retractable mast or retractable fork arm carriage; c) straddle trucks; d) pallet-stacking trucks; e) platform trucks; f) side-loading trucks (one side only); g) lateral-stacking trucks (both sides); h) lateral- and front-stacking trucks (three sides); i) pallet trucks; j) multi-directional lift trucks; k) rough-terrain trucks; l) counterbalance container handlers; m) articulated counterbalance lift trucks; n) order-picking trucks; o) double-stackers. This document is intended to be used in conjunction with ISO 3691-3:2016/Amd 1:2023 for: — Trucks with an elevating operator position of more than 1 200 mm from ground level, — Trucks without an elevating operator position that are designed to travel with an elevated load more than 1 200 mm from ground level, — Trucks with an elevating operator position not exceeding 1 200 mm from ground level that are equipped with an additional load lifting device having a maximum lift height exceeding 1 800 mm from ground level. NOTE ISO 3691-3 does not apply to counterbalance fork lift trucks or trucks intended for container handling. — trucks with an elevating operator position not exceeding 1 200 mm from ground level that are equipped with an additional load lifting device having a maximum lift height exceeding 1 800 mm from ground level. This document provides basic requirements for attachments. Attachments can have additional requirements. Fork arms, load-carrying platforms and integrated attachments are considered to be parts of the truck. Attachments mounted on the load carrier or on the fork arms which are removable by the user are not considered to be part of the truck. This document does not apply to — self-propelled variable-reach trucks (covered by ISO 3691-2:2023); — rough-terrain variable-reach trucks (covered by ISO 10896 series); — burden and personnel carriers (covered by ISO 3691-6:2021), — Lorry-mounted trucks (covered by ISO 20297-1:2017); — towing tractors. NOTE: The requirements for towing tractors will be included in the next revision of ISO 3691-6. This document is applicable to all classifications of internal combustion (IC) engine and electric powered trucks according to ISO 5053-1:2020, Clause B.2. However, it does not establish requirements for hazards related to: — hydrogen fuel cells and hydrogen fuel; — permanent connections to electrical mains supply This document does not provide requirements specifically relating to driverless operation, which are covered by ISO 3691-4:2023. Regional requirements, additional to the requirements given in this part of the ISO 3691 series, are addressed in FprEN 16307-1:2026 for trucks to be placed on the market within the European Union (EU) and European Economic Area (EEA), and ISO/TS 3691-8:2026 for other regions. The requirements are established by the combination of this document and the relevant regional requirements. This document deals with the significant hazards, hazardous situations or hazardous events that are listed in Annex B relevant to the applicable machines when used as intended and under conditions of reasonably foreseeable misuse. This document does not establish requirements for the hazards that can occur: — when operating in severe conditions (e.g. extreme climates, freezer applications, hazardous environments); — during construction; — when handling suspended loads that can swing freely; — when using trucks on public roads; — when operating in potentially explosive atmospheres; — when using trucks in very narrow aisles with clearance of less than 500 mm to the racks; — due to overload while operating; — from contact or creation of an arc with live overhead power lines; — for additional operation from outside the truck other than travelling; — due to radiation emissions from the truck; — when carrying passengers; — due to corruption of the truck control system; — due to contradicting health and safety related sales information; — due to noxious solid materials used; — due to towing; — to operators due to platform acceleration and deceleration for trucks in the scope of ISO 3691-3:2016+A1:2023; — due to constraints from personal protection equipment.
