标准范围

本文件规定了施工标准，建立了性能试验方法，并定义了伸缩式机械螺钉和螺母式牵引杆千斤顶和液压牵引杆千斤顶的验收标准，这些千斤顶拟作为原始设备或替换千斤顶安装在可互换牵引机械的工具舌上[以下简称“工具”）。此外，它还规定了千斤顶制造商提供的最低标记和使用信息。这些千斤顶专门用于-在储存期间支撑机具的挂接点；-提升和降低机具舌片，以便于连接或断开农用拖拉机；和-为固定使用而调平工具。

This document specifies criteria for construction, establishes performance test methods and defines acceptance criteria for telescopic mechanical screw- and nut-type drawbar jacks and hydraulic drawbar jacks intended to be fitted on the implement tongue of interchangeable towed machinery [here after referred to as "implement(s)"] as original equipment or as replacement jacks. In addition, it specifies minimum markings and information for use to be provided by the jack manufacturer.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 an implement for stationary use.
