Construction Equipment Guide

Featuring vertically opening engine hoods designed for easy access to engine and hydraulic components, Bomag’s BW213-40 Series single-drum vibratory rollers are ideal for a variety of site preparation applications, including highway construction and maintenance, airports, streets and subdivisions, parking lots and landfills.

The BW213-40 Series includes the BW213DH-40 smooth drum roller and the BW213PDH-40 padfoot roller, both of which are powered by 160-hp (119 kW) Cummins diesel engines. The BW213DH-40 is designed for compaction of granular and mixed soils, while the BW213PDH-40 is designed for cohesive and semi-cohesive soils.

Dual vibration frequencies and amplitudes allow rollers to be customized for different job site requirements. Both models deliver frequencies of 1,800 and 2,160 vibrations per minute, while each generates 61,825 lbs. of centrifugal force in high amplitude and 44,550 lbs. in low amplitude.

Built for simple maintenance, the BW213-40 Series features maintenance-free steering cylinder pins and travel bearings and a bolt-on articulation joint. The engine air intake is positioned high above the ground to increase filter life, and the hood opens vertically for easy access to the engine, hydraulics and service points.

Improved line of sight to the rear of the each model ensures better all-around visibility for maximum safety. The comfortable design of the vibration-isolated operator platform is enhanced with an ergonomically repositioned steering wheel. An optional swivel seat and a heated and air conditioned cab also are available.

Reduced stop-to-stop steering input makes steering easier and more comfortable for the operator. A 35-degree steering angle and 12-degree oscillation angle provide optimum maneuverability on the job site. Operation is further simplified with a single lever control for travel direction, speed and vibration, according to the manufacturer.

The new models also feature a repositioned, integrated instrumentation cluster. The panel alerts operators to potential problems with engine oil pressure, engine coolant temperature, hydraulic oil filter restriction, air filter restriction, brake control and electrical charge control. Optional compaction measurement systems are now available, as well.

Anti-Slip Control (ASC) systems on the BW213DH-40 and BW213PDH-40 monitor slip potential between the drum and rear tires to maximize traction and gradeability. As a result, the rollers offer maximum gradeability of 55 percent with or without vibration. In addition, both models feature a no-spin differential on rear axles for improved traction.
