Selfloading Superscreen

The Selfloading Superscreen with Shifting Cabin is a screening machine designed for extensive pipeline projects where daily progress is a crucial issue. The machine is suitable for regular grounds and can reach up to 250 m3/h of output material. The Selfloading Superscreen is equipped with a roll-bar-protected air-conditioned shifting cabin.

The Selfloading Superscreen's side-to-side retractable conveyor belt is speed-adjustable and is equipped with a hydraulic deflector. These features allow the operator to adjust the padding material flow and its direction into the trench. An additional rear waste conveyor belt (optional) throws aside the waste material resulting from the screening, allowing the machine to leave behind a "waste-free" ground. This material can be screened by one or two following Superscreens, obtaining more padding layers on the pipe. This working process with 2 or 3 machines in sequence allows fast and effective trench backfilling.
