Overview

ISO 3691-1:2011 - Industrial trucks - Safety requirements and verification - Part 1 - specifies safety requirements and verification methods for self‑propelled industrial trucks (excluding driverless, variable‑reach and burden‑carrier trucks). It is a type‑C standard (per ISO 12100) that applies to a broad range of powered industrial trucks - e.g., counterbalanced trucks, reach trucks with retractable masts, straddle and pallet‑stacking trucks, pallet trucks, bidirectional/multidirectional trucks, tractors (drawbar pull ≤ 20 000 N), rough‑terrain counterbalanced trucks and trucks powered by battery, diesel, gasoline or LPG.

The standard sets out hazards covered (Annex B), verification procedures, marking and information for use, and references related normative documents for testing and assessment.

Key Topics and Requirements

ISO 3691-1:2011 addresses essential technical and safety areas including:

General safety design principles and risk assessment obligations (in line with ISO 12100).
Starting and moving controls and interlocks to prevent unintended motion.
Brakes: performance and component requirements and verification.
Manual control actuators and operator controls (layout, symbols, ergonomic considerations).
Power systems and accessories for electrical and combustion‑powered trucks.
Lifting and tilting systems: mechanical and control safety provisions.
Operator positions (sit/stand/elevating up to 1 200 mm) - access, visibility and protection.
Stability: requirements and references to verification test parts (e.g., ISO 22915 series).
Protective devices, visibility and lighting requirements for safe operation.
Environmental considerations, devices for towing, and limits of applicability (e.g., not for explosive atmospheres or extreme climates).
Verification methods: structural tests and functional verification procedures.
Information for use: instruction handbook content, marking and safety signs.

The document includes normative annexes such as determination of driving direction and rated capacity (Annex A) and an informative list of significant hazards (Annex B).

Practical Applications and Users

ISO 3691-1:2011 is used for:

Manufacturers and designers to design trucks that meet international safety requirements.
Test labs and conformity assessment bodies for type testing, structural tests and functional verification.
Safety engineers and maintenance teams to develop inspection, maintenance and safe‑use procedures.
Procurement and fleet managers specifying compliant equipment for warehouses, logistics, construction and industrial facilities.
Regulators and certification bodies harmonizing national rules with international standards.

Adoption helps reduce accidents, improve operator safety and support global market access for powered industrial trucks.
