ISO 2328:2011

Overview

ISO 2328:2011 is an international standard published by the International Organization for Standardization (ISO) that establishes mounting dimensions and additional requirements for hook-on type fork arms and fork arm carriages used on fork-lift trucks. This standard focuses on ensuring interchangeability of hook-on fork arms and other attachments relative to truck-rated capacity and fork arm type for fork-lift trucks with rated capacities up to 10,999 kg.

By specifying precise dimensional criteria and safety features, ISO 2328:2011 supports manufacturers and users in enhancing compatibility, safety, and operational efficiency when selecting or replacing fork arms and attachments.

Key Topics

• Mounting Dimensions
  The standard defines detailed dimensional specifications for fork carriers and hook-on type fork arms. It covers two main types of fork arms differentiated by the position of the lower hook: Type A (short drop) and Type B (long drop). Compliance with these dimensions ensures that fork arms and attachments can be safely mounted and interchanged on compatible forklifts.

• Interchangeability
  ISO 2328:2011 facilitates the universal use of fork arms by setting standards that permit easy interchange between different manufacturers while matching truck-rated capacities, improving operational flexibility.

• Safety Requirements
  The standard mandates the provision of stops on the fork carrier to prevent lateral disengagement of fork arms, enhancing operator safety. It also addresses optional features such as fork arm removal/mounting slots and specifies warning requirements to avoid unintentional fork arm disengagement.

• Rated Capacity Range
  This standard applies to fork-lift trucks with rated capacities up to and including 10,999 kg, making it relevant for a wide range of industrial trucks used in logistics, warehousing, and manufacturing.

• Referenced Standards
  ISO 2328:2011 refers to related standards for terminology (ISO 2331) and safety requirements for self-propelled industrial trucks (ISO 3691-1), ensuring harmonized implementation alongside broader forklift safety and vocabulary standards.

Applications

• Fork-lift Truck Manufacturing
  Manufacturers use ISO 2328:2011 to design fork arms and carriers that meet international dimensions and safety requirements, enabling compliance and smooth integration with existing equipment.

• Attachment Interchange and Replacement
  Warehouse managers and maintenance teams benefit from this standard when replacing fork arms or fitting compatible attachments, ensuring safe, secure, and quick mounting without custom modifications.

• Quality Assurance and Safety
  Adhering to ISO 2328:2011 helps reduce risks associated with improper fork arm mounting, preventing accidents caused by inadvertent detachment during operation. It also ensures that attachments align correctly with forklift capabilities.

• Global Supply Chain Compatibility
  The standard supports worldwide forklift and attachment interoperability, aiding global logistics and distribution operations by enabling universal fitting dimensions.
