This is what can happen when Mack’s Road Stability Advantage system is turned off.

Mack Trucks now offers a new first-of-its-kind electronic stability control system for concrete customers. Called ‘Road Stability Advantage’ (Mack RSA), it’s made by Bendix Commercial Vehicle Systems. Designed to prevent rollovers, the full electronic stability system is now available for mixer applications on the Granite model.

Mack is the first to offer this technology to vocational customers, though it’s been an option on the company’s highway trucks since late last year.

“Concrete customer demand for stability protection is strong because mixers, in general, are recognized to have a high center of gravity and carry dynamic loads,”
says Steve Ginter, Mack vocational products marketing manager.

Mack RSA uses the existing ABS wheel-speed sensors, along with steering, yaw and lateral acceleration inputs, to deactivate the throttle and selectively apply the brakes in sharp curves, sudden lane changes, or obstacle avoidance maneuvers as necessary, reducing the potential of a rollover.

According to Tom Kelly, Mack’s vice president of marketing, the company is “…committed to getting this technology in the hands of mixer and dump customers as soon as possible. We targeted mixers initially per customer demand. But we’re working very hard with our partner Bendix on other vocational applications as well, to make the technology available across the board in the very near future.”
