Sound Information and Vibration Information

Usage:

416D B2D

关闭的驾驶室的噪音水平

操作员声压级是在推荐的发动机工作转速为 2200 rpm 时测量的。

使用 "ANSI/SAE J1166Oct98"规定的程序进行操作员声压级的测量。 该程序对测量时的工作循环作出了规定。 Caterpillar 提供的驾驶室的操作员声压级为 81 分贝(dB)(A)。 在以下情况下读数正确:正确安装驾驶室, 妥善维护驾驶室, 驾驶室门关闭 和 驾驶室窗关闭.

在开放的驾驶室运行或者在驾驶室没有妥善维护的情况下运行都应采取听力保护措施。 在驾驶室车门或车窗打开时或在嘈杂的环境中也需要采取听力保护措施。

标准机器的外部声压级为73 dB(A)。 使用 "SAE J88Jun86" 中规定的测试流程进行测量。 测量满足以下条件: 距离为 15 m (49.2 ft), 机器位于中档范围 和 移动。
