Backers STERNSIEB – mobile star screener on a trailer chassis from Twist in Emsland: unladen weights from 18,580 to 26,300 kg, gross weight up to 32,000 kg
The STERNSIEB range from Backers is not a trailer in the classic sense but a mobile star screener built on a chassis for road transport. Backers builds it in Twist in Emsland; the designations 3 MA, 3-MAL, 3-MAL 17, 3-MB, 3-MTAL and 3MTA correspond to different equipment levels and screen configurations of the star technology, in which rotating star shafts grade the material.

The register lists here 6 versions with unladen weights from 18,580 to 26,300 kg and a gross weight from 30,000 to 32,000 kg. One version also has a length of 13,900 mm and a width of 2,550 mm.
Star screeners of this size work in earthmoving, composting and the processing of construction and green waste, where they separate material by particle size before further processing or disposal. The chassis design allows the unit to be moved between changing sites without rebuilding it each time. Mounting the screen on axles also allows a quick change to a different mesh size without moving the unit to a workshop.
Buying a used screener of this class, the wear of the star shafts and screen mats, the condition of the hydraulic unit and hoses, the function of the conveyor belts and rust or cracks on the chassis and axles all matter. Brakes, lighting and the chassis's road approval are part of the check, along with the operating hours of the drive engine.

What to check before buying
- Search the frame and welds at the axle mounts — that is where cracks start.
- Check the brakes and the last inspection in the papers.
- Work the gross weight against the towing vehicle before buying.
- Compare the chassis number with the papers.
- Look at the floor, cover or body from the inside — rust does not show from outside.
