AS ISO 24410 pdf download – Earth-moving machinery — Coupling of attachments to skid steer loaders
This document provides for the interchangeability of attachments on skid steer loaders by establishingrequirements for the quick coupler system including dimensional limits for the attachment mountingframe.These quick couplers are typically used on skid steer loaders as defined in ISO 6165.
NOTE 1 Skid steer loaders can use other styles of quick couplers but the coupler would not be interchangeablewith attachments designed to comply with this document.
NOTE2The requirements of this document can be applied to quick couplers used on other compact machines.NOTE 3 Quick couplers used on small skid steer loaders and some compact tool carriers can have a differentwidth requirement than provided in this document. See Annex B.

3.1
attachment
assembly of components that can be mounted onto the skid steer loader lift arm for specific use
[SOURCE: ISO 6746-2:2003,3.5, modified —The term “base machine or equipment”has been replacedwith “skid steer loader lift arm”.]
3.2
quick coupler
device mounted on a skid steer loader to allow quick interchange of attachments (3.1)
[SOURCE: IS0 13031:2016,3.1, modified—The term “earth-moving machine” is replaced by “skid steerloader”, and Note 1 to entry is not included here.]
3.3
attachment mounting frame
attachment component that facilitates the quick mounting and removal of an attachment (3.1) to thequick coupler (3.2)
3.4
engagement system
mechanical system of the quick coupler (3.2) which engages with the attachment mounting frame (3.3)and retains the attachment (3.1) in its working position
[SOURCE: ISO 13031:2016,3.2，modified — The term “attachment”is replaced by “attachmentmounting frame”.]
3.4.1
wedge-type engagement system
engagement system (3.4) of at least two interconnecting parts which engage with one another in awedge action whereby the combination of the wedge angle and the friction coefficient counteract thetendency of the working forces (3.5) to cause disengagement
[SOURCE: ISO 13031:2016,3.2.4, modified —The Note 1 to entry is not included here.J3.5
working forces
forces created by the working operations of the skid steer loader and attachments (3.1) that act uponthe quick coupler (3.2) during intended use and reasonably foreseeable misuse
[SOURCE:ISO 13031:2016,3.3.1, modified — The term “earth-moving machine” is replaced by “skidsteer loader”.]
4 General requirements
The quick coupler system shall be designed in accordance with Clause 5 and the following, using theattachment mounting frame dimensions given in Clause 6 as guidance.
a) The dimensions of the quick coupler should be such that the interface of the vertical face of the
quick coupler and the attachment mounting frame does not result in surface-to-surface contactwhen engaged and locked together. This connection shall result in contact in each of the threezones of interface contact surface between the quick coupler and the attachment mounting frameduring all operating modes of the loader and attachment. The design of the quick coupler may allowa gap between the quick coupler and the attachment mounting frame.See Figure 1.
