Product Description
Scope
The Avant compact screening system is a bucket type attachment fitted either to a hydraulic
excavator or a wheeled loader replacing the standard digging bucket.
The bucket shell is a steel structure with welded joints, integrated driveline cavities, triple
skin floor and wear resistant cutting edge. The shell has been tested up to 1.5x maximum
permissible load.
The horizontal shafts fitted with Polyurethane flexi-stars that rotate in the same upwards
direction. The rotors are supported at each end by a sealed bearing unit and is driven by a
hydraulic motor via a carbon chain belt and drive pulley system.
The hydraulic motor, driveline and bearings are all housed within the main structure of the
bucket with access via a bolted panel. The hydraulic power is produced by the excavator or
wheeled loader’s hydraulic pump and control system via its auxiliary/option circuit, and is
transferred through by flexible hoses to the Avant compact screening system`s hydraulic
motors.
The Non-Hazardous material to be screened is loaded into the Avant compact screening
system in the same manner as a standard excavator or wheeled loader bucket. Once the
bucket has been loaded with material to be screened and positioned, the excavator or
wheeled loaders auxiliary hydraulic circuit is activated causing the star rotors to turn in an
upwards direction.
The efficient screening process is created by the star rotors agitating the material, causing
the fines to flow through the rotating stars leaving the oversize material in the bucket.
Once the screening process is completed the oversize material is tipped out and the
process is repeated.
