May 22, 2012 - Equipment

The Bomag BW138AD-5 tandem vibratory roller features dual travel levers, a foldable roll over protection structure (ROPS), and larger drum diameter for enhanced asphalt compaction performance.

Powered by a Tier 4i 44.6 hp, water-cooled Kubota diesel engine, the BW138AD-5 delivers a maximum centrifugal force of 10,800 lbs. Offering a working width of 54.3 inches, the roller includes larger 35.4-inch diameter drums and provides dual vibration frequencies of 3,480 or 2,820 vibrations per minute (vpm) for more efficient compaction and better surface quality results. Additionally, the roller’s bolt-on oscillating and articulating joint improves maneuverability by allowing the rear drum to follow the same path as the front drum while turning.

A suspended and vibration-isolated operator’s platform includes a fully adjustable seat for added comfort, while allowing clear visibility of the drums. Operator efficiency is enhanced with multifunctional dual travel levers and Smart Drive steering wheel that provides more working room and a full view of all machine controls.

The BW138AD-5 is equipped with a pressure water sprinkler system that includes a high-capacity 81.9-gallon water tank for extended operation intervals between refills. Filtered spray nozzles and automatic interval sprinkler control contribute to water savings, while solid windscreens ensure that the drums receive sufficient coverage even in windy conditions. Flexible, spring-actuated scrapers further contribute to optimum water distribution.

Requiring no daily grease points, the roller is very easy to maintain. Modern circular instrumentation on the dashboard includes warning signals, an hour meter, and a fuel level indicator. Accessible lashing rings, a single lifting point, and integrated towing hook combine to make transport easy and reduce unloading times.

Standard safety features on the BW138AD-5 include foldable ROPS with seat belt, back-up alarm, emergency stop button, and front and rear working lights for night operation. The roller’s engine hood and instrument panel are also lockable to protect against vandalism.
