摘要

The semi-automatic remote-controlled machine checks repairs and restores vertical or nearly vertical conduits such as rubbish chutes, having a tool-holder coupled by rope to a winch and carrying a television camera. The tool holder can also carry lights, electric supply cables, and if necessary hydraulic or pneumatic supply hoses. The tool holder has a tubular tool bracket capable of slewing about the vertical axis of the holder, typically driven by a motor regulated from the control desk. It can also have clamps for fitting different and removable tools, the camera remaining in position.
