不遵守额定负载的规定，有可能造成人员受伤和财产损失。 进行任何作业之前，再次检查作业机具的额定负载。 必要时调整额定负载。 |
注: 额定负载应作为指南。 附件不同、地面不平、地面松软或地面条件很差等，都会影响额定负载。 操作员有责任了解这些影响。
额定负载是基于具有下列条件的标准机器获得的：
- 适当润滑
- 燃油箱满
- 封闭的防滚翻保护结构（ROPS）
- 体重为 80 kg (176 lb) 的操作员
- 45/65-45 轮胎或当量规格
额定负载将随安装的附件不同而异。 关于安装某一特定附件时的额定负载，请向 Caterpillar 代理商咨询。
根据 SAE "J818"（5 月 1987）和 ISO 5998（ 1986）定义，额定工作负载是机器完全转向时静倾翻负载的 50%。

标准提升机器的卸载高度和卸载距离是各个铲斗处在最大提升高度且卸载角度为 50 度的位置时量度的。 卸载高度 (A) 是从地面到铲刃的测量高度。 卸载距离是从前轮胎的前端到铲刃测量的伸出距离 (B) 。
以下表格列出的是配有 1 只铲斗的标准机型配置的额定工作负载。
