本SAE标准适用于SAE J1116中分类的挖沟机。本文仅描述SAE J1234未涵盖的术语。所使用的插图用于说明，并不打算与特定机器相似。只给出了基本的工作尺寸。机器制造商可对其进行补充。本标准适用于任何尺寸的挖沟机，因为大型挖沟机的许多特点也适用于小型挖沟机。

This SAE Standard applies to trenchers as categorized in SAE J1116. Only those terms not covered by SAE J1234 are described herein. The illustrations used are for clarification and are not intended to resemble a particular machine. Only basic working dimensions are given. They may be supplemented by the machine manufacturer. It is intended for this standard to apply to any size trenching machine since many of the features of larger machines are found on smaller trenching machines as well.
