Screen cleaners (trash rake machines) are employed in many places to remove floating and/or suspended debris.
The principle of the Münster travelling grab screen cleaner is based on a construction running along an elevated track, and consisting of a carriage and a loose grab, available in several configurations. The advantage of a loose grab is that screens of any width and depth can be cleaned. The variable track length allows positioning of a deposit at any desirable place.

Special features:

  • narrower or wider grab
  • greater working depth
  • 2-speed drive and lifting motor for different velocities
  • in stainless steel

These screen cleaners are applied in pumping stations, sewage treatment plants, coarse refuse installations, barrages and dams, inlets to power and desalination plants.

Advantages

  • conveyor belts are not required
  • cleaning of the screen, from top to bottom
  • the track can be equipped with curves, enabling the approach of any deposit location
  • possibility of direct dumping on truck, container or barge
  • the open construction and the absence of intermediate transportation reduces space requirements and dirty screening areas
  • large obstacles such as mattresses, tree-trunks and root stems can be removed
  • absence of permanently submerged construction parts and therefore insensibility to icing
  • one unit is sufficient for multi-screen operation
  • PLC control allows complete automatic operation

For smaller intakes a Landy back-raking machine is available.
