Do you also sometimes get disoriented when driving through or working in the sewers? For example, when you are trying to find side connections after renovating the sewer liner? Upper right, so 2 o’clock, and / or middle, 3 o’clock or 9 o’clock? The measuring level from Schwalm provides orientation help when performing precise work in the sewer pipe and helps to avoid any incorrect drilling. It is simply fastened to the tool holder of the rehabilitation robot and is therefore always in the center of the field of vision of the operator through the camera. When raising, lowering and rotating the working arm, the measuring level provides a clearly visible orientation aid using the clock method. A small ball in the hose of the measuring level (similar to with a spirit level) provides a good orientation of the position of the working arm in the canal.
