Three 5/16" galvanized aircraft type cables support the unloader from 3 widely spaced points which result in a level cut from top to bottom.
The drive ring's large diameter along with wall to wall suspension arms guarantee the perfect equilibrium of the machine without counter weight that has to be adjusted every now and then to match silage conditions. Made of 3/16" thick steel, the 3 ring segments feature a big 9' diameter on the 12' to 20' models. They are reversible giving them twice the durability. Double 48" long splice plates provide rigidity to the whole assembly. On the 24' models, ring segments are beefed-up and make a large 11' diameter ring for a stable and well-balanced machine.
The massive 10" heavy-duty auger made of 1/4" thick flighting welded on a 4" O.D. tube for rigidity. It is double flighted at the chipper wheel and to allow the machine to run smoothly in frozen and hard-packed silage. Sharp hardened knives can be installed on auger to chop up to toughest material. Coupled to the gearbox by a 3-bolt flange coupling, the auger assembly is easy to remove.
The Magnum line of surface drive unloaders have become legendary for their performance, durability and efficiency.
With over 50 years experience behind it, the Pow'r Ring leads the way when it comes to silo unloader technology. From its direct coupling drive, large 7'4" drive ring to the exclusive twin "Saber Edge" augers and Hi-Perform impeller, the Pow'R-Ring combines the best in power, reliability and performance.
The Jamesway® Volumaxx silo unloader is the result of more than 60 years of experience and leading-edge expertise in terms of performance and output. The whole idea of a ring-drive unloader is to put the power and leveling requirements on the ring and the hexapod so that the auger can spend its time digging, moving, and blowing.
