A lowerable dust bell with integrated distribution auger ensures virtually dust-free loading of the waste material. The dust bell is suspended from a robust steel frame and can be raised or lowered quickly and easily thanks to the electric winches. The winch is conveniently operated by a control bottle located directly at the loading point. Due to the integrated distribution auger, an optimal volume utilization of the container/trailer is ensured and, with the help of the full indicator, overfilling is prevented.
