标准摘要
[中文适用范围]： 本文件适用于 ISO 5053-1:2020, 3.22 中定义的回转越野可变前移卡车（以下简称卡车），其具有特定的操作员座位，位于动臂左侧，或中心位置（不包括位于动臂右侧的操作员位置）。 本文件规定了一种静态测试方法，用于确定和评估操作员在卡车周围矩形边界和 12 m 能见度测试圆上的能见度。 本文件中指定了可见性的性能要求。 也可以使用计算方法或计算机模拟。 本文档没有提供间接可见性附加方法的性能要求。 本文件还涵盖制造商提供的信息。 [外文原描述]： This document applies to slewing rough-terrain variable-reach trucks (hereinafter referred to as trucks) as defined in ISO 5053-1:2020, 3.22, that have a specific seated operator’s position, on the left-hand side of the boom, or centre position (excluding operator position on the right side of the boom). This document specifies a static test method for determining and evaluating the operator’s visibility on a rectangular boundary close around the truck and on a 12 m visibility test circle. Performance requirements for visibility are specified in this document. A calculation method or computer simulation can also be used. This document does not provide performance requirements for the additional means for indirect visibility. This document also covers information to be provided by the manufacturer.
