Mack Trucks is now offering a new stability system for its vocational concrete mixer chassis to reduce vehicle rollover incidents and thus cut accident costs for fleets.
The system, dubbed the Mack Road Stability Advantage by Bendix, or Mack RSA, is available for mixer applications on Mack's Granite model. Mack RSA uses the existing wheel speed sensors on the truck's antilock brake system (ABS), along with steering, yaw and lateral acceleration sensor inputs, to deactivate the throttle and selectively apply the brakes in sharp curves, sudden lane changes, or obstacle avoidance maneuvers, reducing the potential of a rollover.
Tom Kelly, vp-marketing, noted that Mack began offering full electronic stability technology on its Class 8 highway tractors late last year in conjunction with Bendix, and that the current offering is the first step in the OEM's effort to expand Mack RSA throughout its vocational products as well.
“Engineering this technology for tractors is more straightforward, but we're committed to getting this technology in the hands of mixer and dump customers as soon as possible,” he said. “We've targeted mixers initially, but we're working very hard with Bendix on other vocational applications as well, to make the technology available across the board in the very near future.”
Kelly pointed out that the strong demand for stability control from concrete customers could be attributed to the fact that mixers, in general, are recognized to have a high center of gravity and carry dynamic loads.
