Similar to the Sliding Frame, Schwing Bioset's unique Push Floor Bunker provides a low cost method to store a large volume of material while awaiting final disposal. Typically installed as a truck receiving station, the Push Floor assembly is installed on the floor of the bunker and normally feeds a Schwing Bioset piston pump to incorporate the biosolids into the process stream.

The push floor design consists of a series of hydraulic cylinders that each actuate a push floor inside the bunker. The flights of the push floors can be oriented to convey the material to any location within the bunker for extraction as the push floors reciprocate.
