Mack Trucks is offering customers with concrete mixer applications a lighter-weight solution to meet their demanding needs. The Mack Granite model, equipped with the 2017 Mack MP7 11-liter engine and the Mack mDRIVE HD 14-speed automated manual transmission with creeper gears, is lighter than its predecessor. Mack’s 11-liter MP7 engine received a number of advancements for 2017 designed to simplify maintenance and improve efficiency. The MP7 is about 51 pounds lighter with up to 425 horsepower and 1,560 lb.-ft. of torque.
Mack was the first truck manufacturer in North America to offer low reduction gear ratios in a proprietary automated manual transmission. Along with the Mack mDRIVE HD 14-speed, Mack also offers the mDRIVE HD 13-speed, meeting the needs of an even wider range of customer applications with the performance that only a fully integrated powertrain can offer.
Mack Granite mixers come ready for upfit right from the factory with a rear-engine PTO, a special mixer crossmember designed for mounting of the mixer barrel pump, frame rail transition plates for mixer body mounting and an additional access panel in the cab floor to service the rear-engine PTO.
