BOMAG BW211-50 Single-Drum Rollers Meet Tier IVi Regulations, Deliver Efficient Performance
The BW211-50 Series consists of the BW211D-50 smooth drum roller and the BW211PD-50 padfoot roller.
Both rollers deliver frequencies of 1,800 and 1,980 vibrations per minute across an 84-in. (213 cm) operating width.
Featuring enhanced fuel economy and meeting Tier IVi regulations, BOMAG’s BW211-50 Series single-drum vibratory rollers are designed for efficient compaction of granular and cohesive soils, making them ideal for numerous site preparation and road construction applications, according to the manufacturer.
The BW211-50 Series consists of the BW211D-50 smooth drum roller and the BW211PD-50 padfoot roller. Each model is powered by a Tier IVi compliant, 120-hp (89.4 kW) Deutz diesel engine that features ECOMODE, a system that aids the operator in conserving fuel.
Dual vibration frequencies and amplitudes ensure compaction performance is maximized on a variety of soil surfaces. Both rollers deliver frequencies of 1,800 and 1,980 vibrations per minute (vpm) across an 84-in. (213 cm) operating width. The BW211D-50 generates 53,100 lbs. of centrifugal force in high amplitude and 32,141 lbs. in low amplitude, while the BW211PD-50 provides respective centrifugal forces of 61,825 lbs. and 37,434 lbs.
Maintenance on the BW211-50 Series is simplified by a polymer hood that opens vertically for quick access to the engine, hydraulics and all service points. Steering cylinder pins, travel bearings and a maintenance-free bolt-on articulation joint eliminate daily grease requirements, while the engine air intake is positioned high on the roller to increase filter life and reduce overall noise levels.
Controls on the BW211-50 Series are strategically placed for maximum operator comfort and job site safety.
A vibration-isolated operator’s platform enhances productivity, while clear sight lines provide enhanced all-around visibility of the machine. Additionally, each roller features an ergonomically positioned integrated instrumentation cluster, including audible and/or visual indicators for oil pressure, engine coolant level, brake control, electrical charge control and hydraulic oil level.
A 12-degree oscillating angle and 35-degree steering angle provide optimum maneuverability on the job site, and operation is simple with a single lever control for travel and vibration modes. Heavy-duty 12-ply tires and a rear axle with no-spin differential contribute to excellent traction, even in difficult conditions, according to the manufacturer.
Maximum gradeability is 47-percent with and without vibration.
Options include compaction measurement and control systems, front and rear working lights, padfoot or smooth drum segment kits, front frame or diamond tread rear tire ballasts, ROPS cab with heating, air conditioning, swivel comfort seat, CD radio with auxiliary input, rotary beacon, and special paint. Speedometer, voltmeter, frequency and tachometer gauges also are available.
