The BW120AD-4 tandem vibratory roller, with an operating weight of 5,732 pounds, uses drums that are 47.2 inches wide. The machine delivers a maximum centrifugal force of 10,125 pounds, and provides two vibration frequencies — 3,300 and 4,200 vpm. A standard "crab-walk" feature allows the operator to offset the roller's rear drum up to 1.5 inches in either diection to prevent the drum from striking objects when rolling in and out of turns.
