Bomag launches BW213DH-4 BVC single-drum vibratory roller

The BOMAG BW213DH-4 BVC single-drum vibratory roller features an Intelligent Compaction system for more efficient compaction performance on non-cohesive materials and mixed soils.

Featuring a working width of 84 inches and a dual amplitude vibration system, the BW213DH-4 BVC boasts a 160-horsepower Deutz water-cooled diesel engine equipped with the ECOMODE system, which automatically matches engine speed to roller operation. The roller offers an operating weight of 32,849 pounds and delivers up to 82,125 pounds of centrifugal force. With a frequency of 1,680 vpm, the roller is capable of travel speeds up to 8.7 mph.

To improve efficiency, the BW213DH-4 BVC features BOMAG’s Variocontrol Intelligent Compaction system. Utilizing a directed exciter mechanism, the roller automatically adjusts the output energy of the drum to optimize compaction of the material. This allows the operator to know when maximum density has been achieved, avoiding unnecessary passes and over-compaction of the material. Additionally, an onboard printer allows the operator to document these results.

The roller continuously assesses compaction of the surface and load-bearing capacity of soils and unbound aggregate. It conducts a direct soil-stiffness test during the compaction process using the relationship between the soil contact force and the deflection of the roller drum, thereby giving the operator the ability to identify soft spots and non-uniform areas.

BOMAG’s Anti-Slip Control (ASC) system gives the BW213DH-4 BVC optimal climbing performance, making grades of more than 50 percent attainable. By monitoring the slip potential between the drum and rear rubber tires, ASC automatically adjusts the hydraulic flow between these components for operation on severe grades or difficult traction conditions and to prevent the roller from stalling or “digging” itself into the material.

A gas strut/hydraulically assisted engine hood provides easy access to the engine as well as other key service points. Rubber drum buffers, which reduce vibration feedback to the roller’s frame and operator, can be replaced individually without drum removal, while dual scrapers and wide clearance between the frame and drum prevent material buildup. The roller has no grease-daily points and hydraulic oil changes are required only after 2,000 hours or two years, further reducing maintenance.
