New roller design for perfect bales
The ROLLANT 520 produces bales with a diameter of 1.25 m and width of 1.20 m. The bale chamber has 16 rollers in all, eight of wich are made from 3-mm-thick sheet steel, and the other eight from 4-mm-thick sheet steel. The ribbed profile of the rollers ensures precise rotation of the bale, even under moist conditions. Storage and power transmission functions are performed by the lateral stub shafts. These are flanged onto the roller body, and can be individually replaced if necessary, like the rollers themselves. This construction has proven its worth in the ROLLANT 620 and 540, and is now also available in this entry model.
The baling rollers are driven on both sides. The rotor, main drive and tailgate rollers are fitted with 1.00-inch drive chains. The oil lubricating the chain is pumped from a 4-litre tank with an adjustable eccentric pump. Lubrication is not tied to throughput – the oil is distributed as needed, precisely on the chain link pivot points.
The baling pressure is controlled via the tailgate closing rams. For maximum bale density, pressure of up to 150 bar can be applied to the rams. The MPS II system is available as optional equipment on the ROLLANT 520. With this system, three of the compression rollers pivot into the chamber for additional bale compaction, early bale rotation and a perfectly uniform bale shape.
