ISO 23206:2005

Overview

ISO 23206:2005 is an international standard developed by the International Organization for Standardization (ISO) that specifies the dimensions and clearance requirements for carriages used to mount attachments on front loaders fitted to agricultural wheeled tractors. This standard applies to front loader systems with a maximum load capacity of 30 kN and tractors weighing up to 7,500 kg when unladen.

The standard ensures compatibility, safety, and interchangeability of attachments such as buckets, forks, or other tools that can be mounted on front loaders used in agriculture. By harmonizing carriage dimensions and clearances, ISO 23206:2005 facilitates efficient tractor attachment operations and improves safety for farmers and operators.

Key Topics

• Carriage Dimensions and Clearances: Defines precise measurements for the carriage structure, including the clearance zones necessary around hooks, eyelets, and attachment buffers to ensure proper fit and operation.
• Locking Device Requirements: Specifies the design and placement of locking pins on the carriage, which can be located inside or outside the frame, with mechanisms for safe locking and unlocking from the driver's seat or nearby positions.
• Attachment Mounting Interface: Addresses the recommended mounting height for eyelets on attachments with a suggested distance of 150 mm from the base surface to the center of the eyelet to facilitate proper coupling.
• Load Capacity Specifications: Focuses on the maximum vertical lift capacity measured at 800 mm in front of the locking pin to assess the carriage and front loader capability, supporting loads up to 30 kN.
• Safety and Visual Indicators: Mandates that operators must have a clear visual confirmation that attachments are securely locked to the carriage, minimizing risks during attachment changes and operation.

Applications

ISO 23206:2005 is essential for manufacturers, designers, and users of agricultural wheeled tractors and front loader attachments. Practical applications include:

• Agricultural Machinery Manufacturing: Ensures that front loader carriages produced by different manufacturers are compatible with a wide range of attachments, promoting standardization and reducing design complexity.
• Attachment Production: Allows attachment manufacturers to design tools and implements that fit shaft carriages precisely, enhancing reliability and ease of use for end-users.
• Farm Operations: Helps farmers safely and efficiently swap front loader tools to perform diverse tasks including loading, lifting, and soil management.
• Maintenance and Safety Compliance: Provides guidelines for routine checks on locking mechanisms and clearances to maintain equipment safety and operational effectiveness.
• Equipment Rental Services: Facilitates standard interfaces, enabling rental companies to stock compatible attachments usable across different front loader models.
