The wobbler grid of "GR" series is a simple and rugged machine, particularly recommended to primary plants for its ruggedness in supporting large-sized materials and previous screenings of soiled, clayey or damp material.

The machine is manufactured with very thick structural shapes, the shafts in manganese steel are supported externally by grease lubricated bearings. The machine is armoured inside with a sheet resistant to wear.

The transmission occurs by means of a reduction gear, through grease lubricated chains.
