标准摘要
[中文适用范围]： ISO 6489 的本部分规定了用于连接农用牵引车的牵引式非平衡拖车和配备 ISO 5692-1 中规定的耦合环的机具的岩钉式耦合装置的尺寸要求。 其目的是确保农用牵引车上机械连接的互换性。 仅适用于垂直静载荷不超过30 kN的情况。 [外文原描述]： ISO 6489-4:2004 specifies the dimensional requirements for the piton-type coupling devices used in the attachment to agricultural towing vehicles of towed, non-balanced trailers and implements equipped with a coupling ring specified in ISO 5692-1. Its purpose is to ensure the interchangeability of the mechanical connections on agricultural towing vehicles. It is applicable only in those cases where the vertical static load does not exceed 30 kN.
