What is ISO 24410 about?
ISO 24410 is an International Standard that discusses earth-moving machinery. Given the ISO 24410 provides guidance on the quick coupler system's design principles for efficient operation and interoperability of the overall machinery. ISO 24410 provides for the interchangeability of attachments on skid steer loaders by establishing requirements for the quick coupler system including dimensional limits for the attachment mounting frame. These quick couplers are typically used on skid steer loaders as defined in ISO 6165.
Note: Skid steer loaders can use other styles of quick couplers but the coupler would not be interchangeable with attachments designed to comply with ISO 24410.
Note: The requirements of this document can be applied to quick couplers used on other compact machines.
Note: Quick couplers used on small skid steer loaders and some compact tool carriers can have a different width requirement than provided in this document. See Annex B.
Who is ISO 24410 for?
ISO 24410 on the coupling of attachments to skid steer loaders is relevant to:
- Machine manufacturers
- Skid steer loader manufacturers
- Quick couplers manufacturers
- Machine designers 
- Mechanical engineers 
Why should you use ISO 24410?
Earth-moving equipment is large machinery, mainly heavy-duty vehicles designed for earthwork construction tasks. As quick couplers typical to skid steer loaders are used with various types of compact products, the growth of the use of this style quick coupler with other products has resulted in the need to provide guidance regarding the design principles of this quick coupler system.
By adopting the design principles established under ISO 24410, you will be able to improve functionality of the earth-moving machine given the interoperability of skid steer loader with different attachments. With specified frame dimensions, you can also facilitate the seamless mounting and removal of an attachment to the quick coupler, thereby reducing time, effort and fuel consumption in completing construction and landscaping projects.
What’s changed since the last update?
BS ISO 24410:2020 supersedes ISO 24410:2005, which is withdrawn. BS ISO 24410:2020 includes some technical changes with respect to ISO 24410:2005. These include:
- Addition of safety requirements
- Addition of informative annexe regarding the mechanics of a skid steer loader quick coupler
- Addition of width dimensions for narrow skid steer loader attachment mounting frame
