EN ISO 3691-3:2016 PDF

Overview

EN ISO 3691-3:2016 - Industrial trucks - Safety requirements and verification - Part 3 - specifies additional safety requirements and verification for industrial trucks that have a vertical, non‑tilting mast and either an elevating operator position or are specifically designed to travel with elevated loads. It complements ISO 3691‑1 and focuses on trucks where the operator position or load‑handling device exceeds 1 200 mm above ground. The standard applies to indoor trucks designed to travel on smooth, level surfaces (e.g., concrete) and covers guided or unguided operation. It does not cover road use, potentially explosive atmospheres, certain stacker trucks, or trucks with lift heights up to and including 1 200 mm.

Key Topics

• Scope and hazards: Defines applicable machine types and lists significant hazards relevant to elevated travel (Annex A).
• Operational modes: Safety measures for lateral‑ and front‑stacking trucks and order‑picking trucks when travelling with elevated loads.
• Braking and travel speed: Requirements for brakes and reduced travel speeds when the operator or load is elevated, including differences for guided systems.
• Controls and ergonomics: Requirements for operator controls, clearances and the elevating operator position to ensure safe use at height.
• Lifting and lowering systems: Safe design, verification and emergency lowering provisions for elevated platforms and load‑handling devices.
• Operator position & visibility: Design measures to protect an operator situated in an elevated position, including guarding and access.
• Optical warning devices & stability: Requirements for visual warnings and stability verification when travelling with an elevated load.
• Verification & documentation: Test methods, conformity verification, marking, installation information and instruction handbook requirements additional to ISO 3691‑1.

Applications

EN ISO 3691-3:2016 is used to:

• Ensure design and safety compliance for trucks with elevating operator positions (order pickers) and trucks that travel with elevated loads.
• Guide type testing and verification for manufacturers and conformity assessment bodies.
• Define safe operating limits and instructions for warehouse fleet managers, safety officers and maintenance teams.
• Support compliance with the EU Machinery Directive (2006/42/EC) when cited as the harmonized standard.

Who should use this standard

• Truck manufacturers and design engineers
• Certification and testing laboratories
• Occupational health & safety professionals and fleet managers
• Compliance engineers preparing technical documentation for CE marking

Related Standards

• ISO 3691‑1 (general safety requirements for self‑propelled industrial trucks)
• ISO 5053‑1 (definitions for order‑picking and stacking trucks)
• ISO/TS 3691‑7 / 3691‑8 (regional requirements)
• EN 16307‑3 (supplementary European requirements)

Using EN ISO 3691-3:2016 helps reduce risks associated with elevated operation of industrial trucks and provides clear verification steps for manufacturers and users to demonstrate safe design and use.
