Mack Trucks Inc. will showcase its TerraPro refuse series lineup, including a natural gas-powered version, and roll out several new product enhancements during Waste Expo 2011 in Dallas. Introduced in Oct. 2010 at the Mack World Sales Conference, the NG-powered version of the TerraPro Cabover gives customers an alternative fuel option for demanding refuse applications.
“The TerraPro Cabover is an excellent example of Mack’s dedication to innovation and application excellence,” says Curtis Dorwart, Mack vocational products marketing manager. “The refuse segment in particular is well suited for alternative fuel technologies, and Mack has continued to deliver as our customers begin migrating toward natural gas vehicles.”
The TerraPro Cabover model is equipped with a 9L 320-hp Cummins Westport ISL G engine that can use compressed (CNG) or liquefied natural gas (LNG). The heavy-duty engine has a three-way catalyst designed to meet U.S. Environmental Protection Agency 2010 emissions standards.
Headlining the new products on display at the Mack booth (No. 3035) will be the initial offering of Mack Air Disc Brakes, engineered specifically for vocational applications. Mack says it has optimized the balance between friction material and rotor material for the stop-and-go needs of the refuse industry, providing improved stopping distance and handling. The air disc brakes are engineered for easier service, and the friction material has been designed to last twice as long as the material in S-cam drum brakes.
To reduce cost and weight as the market trends toward lighter truck specs and higher payloads, customers also now have a new Allison automatic transmission option – the 3000 series – for the TerraPro model. Mack customers also can opt for Allison’s hydraulic retarder to help slow the vehicle during routine stop-and-go driving, reducing stress on service brakes.
The TerraPro Low-Entry model also will receive an upgraded factory-installed air-conditioning unit to help improve driver comfort. The roof-mounted system will cost less than the previous unit and is designed to improve airflow by more than 50 percent.
“Mack has long been a leading player in the refuse segment, and we continue investing and innovating to produce the best possible solutions for our customers and their unique applications,” says Kevin Flaherty, Mack senior vice president, U.S. and Canada. “Our latest TerraPro enhancements will further improve productivity, safety and operational efficiency.”
