Bomag Redesigns 56-Inch Single-Drum Rollers

Size, versatility, low maintenance ideal for the rental market

ATLANTA - BOMAG introduces its redesigned BW145-40 Series single-drum vibratory rollers, with improved operator ergonomics, better service point access and a 75-horsepower Tier III-compliant Deutz diesel engine. Ideal for rental applications, this roller will be on display at the Rental Show in Atlanta, March 2-5, 2009.

With a 56-inch wide working width, the BW145-40 is large enough to handle medium-sized projects like driveways, parking lots and residential and commercial construction. Yet it is small enough to work in confined spaces. Its high centrifugal force and optimized frequency and amplitude ensure maximum versatility on a wide range of materials.

The new roller series includes three models: the BW145D-40 and BW145DH-40 smooth drum rollers and the BW145PDH-40 padfoot roller. The BW145D-40 and BW145DH-40 are designed for compaction of granular and mixed soils, while the BW145PDH-40 is designed for cohesive and semi-cohesive soils.

With several features that simplify or even eliminate maintenance, the BW145-40 Series rollers are ideal for the rental market. The vertically opening engine hood provides full access to the engine, hydraulics and cooling system, making daily checks simple for the operator and service technician. The BOMAG oil filter system extends oil and filter change intervals to 2,000 hours or two years. The exciter system and brakes are virtually maintenance-free.

The vibration-isolated operator's station has been enhanced with an ergonomically repositioned steering wheel and a new integrated instrument cluster that alerts operators to potential problems with engine oil pressure, engine coolant temperature, hydraulic oil filter restriction, engine air filter restriction, brake control and electrical charge control.

The BW145-40 Series rollers are also easier to control and operate. A single lever controls travel direction, speed and vibration. Steering is efficient and more comfortable and the line of sight has been improved to the rear of each model, ensuring better all-around visibility.

The heavy-duty axle features a self-locking differential to ensure full engine power and traction at all times. In addition, the BW145DH-40 and BW145PDH-40 offer dual travel pumps for enhanced gradeability. Powerful oil-immersed SAHR brakes apply automatically on engine shut down or when emergency stop is activated.

Standard dual amplitude and vibration frequency allow the BW145-40 Series rollers to be customized for different jobsite requirements. All three models deliver frequencies of 2,040 vibrations per minute, while each generates 22,500 pounds of centrifugal force in high amplitude and 11,250 pounds in low amplitude.

The drum exciter system is virtually maintenance-free while a centralized electrical panel permits systematic and efficient troubleshooting. The bolt-on design of the oscillating/articulating center joint simplifies replacement, if necessary. Drum vibration buffers can be replaced individually without the need for special tools.

Available options include ROPS cab with heating, air conditioning, work lights, leveling blade (BW145DH-40 and BW145PDH-40 only) and smooth and padfoot shell kits.
