Mack Trucks is showing three natural gas TerraPro models this week at Waste Expo 2012 in Las Vegas. Two cabover models and one low-entry model, all equipped with Cummins Westport ISL-G natural gas engines, are part of Mack’s booth, which also includes a tandem-steer version of the TerraPro cabover as well.
“Natural gas is readily available in the U.S. and is a viable solution for the refuse segment,” said Curtis Dorwart, Mack vocational products marketing manager. “As the dominant supplier of heavy-duty refuse trucks, our customers have turned to Mack for solutions, and we have responded with natural gas-powered versions of our TerraPro cabover and TerraPro low entry models built to withstand the rigorous needs of their applications.”
The natural-gas models meet EPA 2010 and CARB emissions levels.
The tandem-steer model is designed and engineered to maximize weight distribution, Mack said. The tandem-steering option allows both front axles to steer and enhances payload and productivity for customers in refuse and recycling applications.
It is equipped with a low-weight chassis and Simard suspension, which was adapted to optimize payload capacity. The model on display at Waste Expo is a front-loader configuration powered by a Mack MP7 325 hp. Maxidyne diesel engine.
“The load-equalizing tandem-steer TerraPro model enables greater payload to maximize revenue for our customers,” Dorwart said. “The twin steer feature coupled with a low-weight chassis allows certain Canadian applications an extra edge in productivity.”
