BS ISO 24410:2020 pdf free.Earth-moving machinery – – Coupling of attachments to skid steer loaders.
BS ISO 24410 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 frame. 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 other compact machines.NOTE3 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.The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.ISO 6165, Earth-moving machinery一Basic types一- Identification and terms and definitions ISO 13031:2016, Earth-moving machinery一Quick couplers一Safety.The linkage of the quick coupler to the loader lift arms should provide a minimum of 5° 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.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 scarifier attachment).See Figure A.2.The dimensions for the attachment mounting frame shall be as shown in Figures 2 to 5. 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 b] and 3 b] for dimensions of area that centre support structure may be allowed.BS ISO 24410 pdf download.
