AS ISO 24410:2021 pdf free download – Earth-moving machinery -Coupling of attachments to skid steer loaders.
This document 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 Irame. 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 interchangeable with attachments designed to comply with this document.
NOTE 2 The requirements of this document can be applied to quick couplers used on othercompac I machines.
NOTE 3 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 Aune.’ B.

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 replaced with skid steer loader lift arm”.]
quick coupler
device’ mounted on a skid steer loader to allow quick Interchange of attachments (11)
(SOURCE: ISO 13031:2016. 3.1, modified — The term earth-moving machine” is replaced by “skid steer loader’, and Note 1 to entry Is not included here.I
3.3
attachment mountIng frame
attachment component that facilitates the quick mounting and removal of an attachment (3.1) to the quick coupler (3.2)
— below surface C.
NOTE Some attachments could require added support structure to the attachment mounting frame between surfaces A and B.
c) The linkage of the quick coupler to the loader lift arms should provide a minimum of 50 rollback beyond vertical of the quick coupler towards the loader with the lift arms in their lowest position. The amount of rollback may be less for quick couplers used on smaller skid steer loaders, compact tool carriers and other compact equipment.
5 Safety requirements
A skid steer loader quick coupler shall comply with the requirements of ISO 13031:2016. 4.1, for a wedge-type engagement system.
NOTE A skid steer quick coupler is a combination of two different wedge-type engagement systems. See Annex A for further information on how these diflerent wedgetype engagement systems apply to the skid steer quick coupler system.
The wedges/pins of the quick coupler shall engage the attachment mounting frame at the wedge/pin contact surfaces (see Figure 1) when the attachment is properly connected.
Ci Standards Australia Limited 2021
AS1S024410:2021 4
The locking system shall prevent retraction of the wedges/pins from attachment mounting frame during operation of the loader with the attachment when the working forces are pulling the attachment mounting frame in a direction away from the quick coupler (e.g. forcing a bucket against the ground pushing upward on the bottom of the bucket, loader traveling rearward with a scantier attachment). See Figure A.2.
6 Attachment mounting frame dimensions
The dimensions for the attachment mounting frame shall be as shown in Figuri 2 to S. The attachment shall only have components outside the described space.
Some attachments can require added support structure to the attachment mounting frame between surfaces A and B In Figure 5. See Figure 2 h) and 3 b) for dimensions of area that centre support structure may be allowed.
