真空吸土车：市政、电力的好帮手

Introduction of German Brand of Vacuum Suction Excavator

国内已先后出现了真空吸粪车、真空吸污车、真空吸尘车（扫路车）等依靠真空原理工作的专用汽车，但笔者还未听说过有真空吸土车这种产品。据了解，目前真空吸土车只有极少数国家生产和使用。

This article introduced basic operating principle, structural features and practical application of the vacuum suction excavator manufactured by German based RSP GmbH Company. This special purpose vehicle was specifically designed for operation for underground cable, tunnel emergency repair and digging for tree or post/stake, etc. Now, this kind of excavator is only put into operation in few countries.
