Mack®m DRIVEHD Debuts in Mack TerraPro® Cabover Concrete Pumper Models

LAS VEGAS – (Jan. 22, 2019) – Mack Trucks will offer the Mack®m DRIVEHD automated manual transmission (AMT) in Mack TerraPro®concrete pumper models beginning in 2019, marking the first time in the industry that an AMT has been available in a cabover concrete pumper. The fully integrated 13- and 14-speed m DRIVE HD AMTs give concrete pumper customers improved performance, proven durability and maximized uptime in an easy-to-operate package. Mack made the announcement at World of Concrete 2019 in Las Vegas. “The m DRIVE HD is the only AMT available with split-shaft PTO functionality, which enables us to offer concrete pumper customers all the benefits of the m DRIVE HD and our fully integrated powertrain,” said John Walsh, vice president of marketing for Mack Trucks. “In addition to improved performance and productivity, the m DRIVE HD helps increase jobsite safety. Eliminating traditional shifting allows drivers to focus on safely operating their equipment.” All Mack m DRIVE HD AMTs come standard with split-shaft PTO functionality. Instead of taking power from a transmission- or engine-mounted PTO, split-shaft PTOs receive output directly from the transmission, supplying higher torque for large auxiliary equipment including concrete pumps. The Mack m DRIVE HD is fully integrated with Mack’s legendary engines and axles, providing additional performance and efficiency benefits for customers. In TerraPro concrete pumpers, the m DRIVE HD will be paired exclusively with the 11-liter Mack MP®7 engine, and will be available with higher horsepower and torque ratings than equivalent models with conventional automatic transmissions. That includes the MP7’s top rating of 425 horsepower and 1,560 lb.-ft. of torque, which packs 13-liter power in an 11-liter engine. The m DRIVE HD for TerraPro concrete pumper models is available as a 13-speed direct drive or overdrive, as well as a 14-speed direct drive.

“For more than 100 years, Mack has held firm to the belief that components designed work together simply work better,” said Tim Wrinkle, Mack construction product manager. “Not only do our integrated components deliver higher performance, they also help maximize uptime for our customers.” Like all Mack m DRIVE AMTs, the m DRIVE HD in TerraPro concrete pumper customers will be monitored by Mack’s GuardDog®Connect telematics solution. GuardDog Connect, which comes standard on all Mack models powered by Mack engines, provides proactive monitoring and repair planning, real-time diagnosis of issues, repair scheduling and confirmation that needed parts are in stock and ready to install. Together with Mack ASIST and Mack’s OneCall uptime experts, GuardDog Connect delivers decision-critical information to maximize customer uptime. The m DRIVE HD offers customers simplified maintenance compared to conventional automatic transmissions, with service intervals of up to 500,000 miles. If the m DRIVE HD does require service, customers can simply visit any authorized Mack dealer, eliminating the additional time and hassle of visiting a third party service location. Mack’s m DRIVE HD is based on the proven design of the m DRIVE, which has been standard in Mack highway models since 2014. With ruggedized internal components, including stronger gears and synchros, the m DRIVE HD is built to withstand the frequent shifting often found in construction applications. The 13- and 14- speed variants also feature low-ratio creeper gears, enabling the m DRIVE HD improved startability and ultra-low speed maneuverability. All m DRIVE HD AMTs feature a transmission-mounted oil cooler to help maintain optimal operating temperatures, even in the face of repeated, heat-generating shifts commonly found at jobsites. The m DRIVE HD also includes advanced standard features like Rock Free, which allows drivers to free stuck vehicles by rocking the truck back and forth simply by pumping the accelerator, and Auto Neutral, which improves jobsite safety by automatically putting the m DRIVE into neutral when the parking brake is set. Additional features like Grade Gripper, which helps prevent rolling backward on an incline, are also included, as well as MaxBrake, Performance Mode and more. The Mack m DRIVE HD in Mack TerraPro concrete pumper models will be available for order in February 2019. For more information, visit Mack Trucks at World of Concrete 2019 in booth C5103.
