标准摘要
[中文适用范围]： 本文件规定了安全要求、测试程序，并制定了伸缩式机械螺钉和螺母型牵引千斤顶和液压牵引千斤顶的应用的最低验收标准。这些千斤顶旨在安装在可互换牵引机械的机具舌片上，以下称为“机具”，作为原始设备或装有千斤顶附件支架的千斤顶。本文件适用于机具安装千斤顶或装有千斤顶附件支架的千斤顶。这些千斤顶专门用于在储存、提升和降低机具舌片期间支撑机具的挂接点，以便于连接或断开与农业拖拉机的连接以及调平机械以供固定使用。牵引杆是设计用于与牵引车辆的机械连接件耦合的牵引杆。 [外文原描述]： This document specifies safety requirements, test procedures, and establishes minimum acceptance criteria for the application of telescopic mechanical screw- and nut-type drawbar jacks and hydraulic drawbar jacks intended to be fitted on the implement tongue of interchangeable towed machinery and hereafter referred to as "implement(s)" as original equipment or jacks fitted with a jack attachment mount. This document applies to implement mounted jacks or jacks fitted with a jack attachment mount. These jacks are used specifically for supporting the hitch points of implements during storage, lifting and lowering of implement tongues to facilitate attaching to or disconnecting from an agricultural tractor and levelling of machinery for stationary use. The drawbars are those which are designed to couple with the mechanical connections of towing vehicles.
