Niederberger-Engineering AG for the Villiger AG (Oberrüti, Aargau) developed two waste disposal systems which hidden the waste in underground containers, but easily can be emptied too.
Niederberger-Engineering AG designed the disposal pillars with weight and volume mesurement and the lifting system for both units.
Lift-o-Mat LU 300-600
By this system the garbage is moved to the container which is stored below the pillar.
This containers can be changed using a hydraulic lifting system.
Using this variant, the waste falls into a underground box too.
The difference is, that this container is emptied by a crane crab specially designed for this purpose.
The crane which empties the containers was constructed by Niederberger-Engineering too. It can be found at Container crane.
