摘要

A sanitation machine is useful for repairing damaged ducts that cannot be accessed for repair. The sanitation machine is driven by remote control and monitored by television cameras. Various tools required for carrying out repairs may be arranged on a motor-driven, rotary tool carrier at the head of the driving carriage. On the undercarriage of the sanitation machine is mounted a hollow shaft (5) parallel to the direction of travel carrying at one end holding means (6) for one or more tools. Among the holding means (6), at least one can be moved in order to displace the tool or tools in a roughly radial direction. The inner space of the hollow shaft (5) receives cables leading to the tools.
