- KD is used in WWTPs for space-saving handling of containers. It includes mobile chassis on rails that allow for the transport of containers among buildings from technological equipment to transport space.
- it is used in locations with insufficient space for emptying and replacing of the containers with screenings or sludge.
- a hand lever or an electric gearbox with a drum reel can be used to drive the chassis.
- container rail transport is particularly suitable for the buildings with low handling height, as the transport of containers is relocated to the outside.
