OSSBERGER - Model RRH -Stationary Hydraulic Hydropower Trash Rack Cleaner
Ossberger developed the stationary, hydraulic trash rack cleaner of type RRH for the automatic cleaning of small and medium-sized trash racks installed at water intakes of channels and storage basins. This machine is equipped with single-arm, wide extending angle booms, on which the cleaning rake is attached perpendicular to the river flow. The boom consists of two arms jointed by a pivoting bearing. Hydraulic cylinders move the rake up and down according to the geometry of the screen. Additionally, the traction arm can be furnished with a telescopic extension; a hydraulic aggregate controls the oil supply.
- Screen width: 0,5 – 8 m
- Screen length/intake depth: 0,8 – 10 m
- Inclination: 30° – 75°
The rake type RRH includes a storage-programmable logic controller and a level differential control device for automated operation. Maintenance requirements are kept to a minimum, yet designed to operate efficiently and reliably for many years. The rake type RRH 5 is the latest model in this series of trash rack cleaner design and is capable of reaching cleaning depths of up to ten meters.
