BOMAG upgrades recycler/stabilizers
BOMAG has improved key drive-train components on its 79-inch rotor width asphalt recycler/soil stabilizers. Both the MPH362-2 and MPH364-2 models have been repowered with a six-cylinder, electronically-controlled 360 hp Cummins QSM11 water-cooled diesel engine, which is Tier 3 Stage III EPA certified. Other improvements include the use of a double reduction planetary rear drive system, which is propelled by a pair of axial-piston variable displacement motors. The drive system on previous models used a ring and pinion differential assembly. The new hydrostatic system demands less horsepower than ring and pinion systems, which results in improved fuel economy. Additionally, overall cost of ownership is reduced due to fewer wear parts to maintain and repair. Upgrades to control systems and changes to electronics have also been implemented.
The MPH362-2 is a rear-wheel drive machine, while the MPH364-2 uses four-wheel drive to enhance performance on severe grades or in diffi cult traction conditions. An Automatic Power Adjustment System (APA) automatically adjusts forward travel speeds to match the application and material being processed. Both models are available with one of three rotor confi gurations, including an asphalt-recycler rotor designed to cut, pulverize and mix old and deteriorated asphalt pavement for reuse as road base material. Each rotor – recycling or stabilizing – is 79 inches wide and offers rotor speeds of 135 and 150 revolutions per minute. The recycler rotor features 168 bullet-shaped cutting teeth, while the stabilizer rotor offers 70 paddle-shaped teeth. The teeth are strategically positioned for uniform material pulverizing, sizing and mixing with minimum vibration and shock load to the rotor and drive components.
