The new, compact BOMAG BW 120 AD e-5 electric tandem roller introduces sustainable, low-noise and zero-emissions operation to the 2.5-ton class commercial roller market. With its 39.4-in (1,000 mm) rolling width, this powerful and versatile machine makes short work of parking lot, driveway, and asphalt repair.
Featuring a low-voltage, 48V system with long-lasting 25 kWh Li-Ion batteries, the system requires no special safety precautions for maintenance, and the batteries offer plenty of capacity for a typical day’s work before recharging.
The new tandem roller’s efficient e-PERFORMANCE system is equipped with two electric motors – one dedicated to travel and the other for steering and vibration. A 26.8-hp (19.7 kW) electric motor propels the front and rear driven drums at working speeds of 0-3.1 mph (5.0) and travel speeds reaching 6.2 mph (10 kmph).
With no warm-up necessary, the roller is quickly ready for work at the push of the ignition button. A digital 5-in (127-mm) color display gives operators a quick glance of critical operating parameters, including speed, energy output, asphalt temperature, compaction progress, operating hours, battery charging capacity, duration and power.
The electric BW 120 AD e-5 flexibly allows for individual vibration control to both drums, and vibration actuation is conveniently controlled through the soft-response travel lever. Tailoring compaction output to the job, the roller offers two vibration frequencies of 3,360 and 3,900 vpm (54 and 64 Hz) with a single amplitude of 0.20 in (0.50 mm), generating 5,395 and 7,194 lb (24 and 32 kN) centrifugal force. Its intelligent vibration control (IVC) helps operators to know when compaction has been optimized to save on passes. Featuring a pressurized water spray system with 54.2-gal (205-l) tank, the scraper bars are wind-protected to ensure uniform drum coverage in adverse weather conditions.
