Short project description:

The wood collector is used to remove floating refuse such as driftwood from the reservoir of the Lutz “Oberstufe” power station.

The complete machine is able to travel along the dam on a rail system. The vehicle weighs around 14 tonnes and is powered by 4 Demag wheel block units. As the approx. 92m-long route contains a curve, all 4 drives are powered separately to ensure smooth handling.

The drives are powered by a pendant control panel. When command to start the crane is received, the hydraulic clamp that protects against tilting is closed and the Fassi crane with a swivel range of 400° is supplied with oil.

In addition to collecting floating refuse, driftwood and sediment, the machine also has numerous other functions.
