Rental-Friendly Roller Moves Forward

By Mike Anderson, Senior Editor | September 28, 2010

Bomag has redesigned the 47-inch single-drum vibratory roller model to provide more standard features popular in the rental industry and among cost-conscious contractors. With their compact design, the new BW124-40 Series rollers are versatile and maneuverable, yet offer capabilities similar to larger models.

It may be a member of the Bomag heavy compaction product family, but the BW124-40 Series vibratory roller was right at home being launched at The Rental Show 2008.

With a 47-inch drum, the smallest of Bomag's heavy single-drum rollers is "a perfect machine" for the rental market, says Dave Dennison, product manager, Bomag Americas. Beyond avoiding transport restrictions, "it's got the ability to be used in confined areas — utility installations, landscaping jobs — applications that are really in that rental niche."

Rolled out at the American Rental Association's annual February trade show, held at the Mandalay Bay Convention Center in Las Vegas, the smooth-drum BW124DH-40 and the corresponding padfoot-drum BW124PDH-40 feature noticeable design enhancements from the predecessor BW124-3 Series that go beyond the new Tier-3 Deutz three-cylinder diesel engines. These include ROPS/FOPS with a sun canopy as standard and a more vertically opening hood.

"It's not a truly 90-degree-opening hood, but we're closer than we were. It was improved over the old model and gave us more access to the engine compartment," says Dennison. "It brings us more in line with the rest of the family."

While not a new feature, "the ability to outfit these machines with a blade also increases the versatility of the machines and reduces reliance on other equipment," says Dennison. "Because of that machine's size and its utilization in utilities or trench work and in landscaping, it's definitely a benefit to have the blade, whether it's for rental or contractor."

With a vibratory system generating 18,540 foot-pounds of centrifugal force, the BW124-40 Series will compact granular and mixed soils, as well as semi-cohesive and cohesive materials. A dual amplitude option is available.

No-spin rear differentials and standard drum drive combine for maximum gradeability of 55 percent. The bolt-on, maintenance-free center joint provides 35 degrees of articulation and 12 degrees of oscillation for full drum contact on irregular terrain.

A single travel lever provides simple control for travel direction and speed, topping out at 5.6 miles per hour. While adding the Tier-3 engines, the updated BW124-40 rollers maintain an ISO-rated output of 44 horsepower.

Bomag Americas also recently rolled out the updated 66-inch BW177-40 and 84-inch BW211-40 Series single-drum vibratory rollers.
