Mack offers stability system on vocational trucks

Truck News

LAS VEGAS, Nev. — Mack has announced it’s now offering a stability system for concrete customers.

Mack Road Stability Advantage (Mack RSA) is a first-of-its-kind stability system developed by Bendix, the company says. It is designed to reduce incident potential while enhancing profitability and is available for mixer applications on the Mack Granite.

“We’re very proud to be the first heavy-duty truck manufacturer to offer this technology to vocational customers,” said Steve Ginter, Mack vocational products marketing manager. “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.”

Mack RSA uses the existing ABS wheel sensors along with steering, yaw and lateral acceleration inputs to deactivate the throttle and selectively apply the brakes while cornering or performing sudden lane changes or other avoidance maneuvers. This reduces the potential for a rollover, the company says.

The system has been offered in Mack’s highway tractors since last year.

“Engineering this technology for tractors is more straight-forward,” said Tom Kelly, Mack vice-president of marketing. “But as a leader in the heavy-duty vocational truck market, we’re 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.”
