At the World of Concrete show in Las Vegas, Mack Trucks introduced a new split-shaft functionality for its Mack mDrive HD automated transmission, giving customers with high-demand power take-off needs a fully integrated solution.
Split-shaft PTOs are mounted in the middle of the driveline to receive input directly from the transmission, supplying more torque for auxiliary equipment such as concrete pumps, vacuum body or high-pressure liquid transfer applications.
While the split-shaft PTO is engaged, power to the axles is disconnected. The split-shaft functionality is standard on all 12-,13-, and 14-speed mDrive HD AMTs and can be activated by a Mack dealer.
Additionally, all F-Series mDrive HD AMTs can be reprogrammed with split-shaft functionality with assistance from the Mack Body Builder Support Group. The functionality allows transmissions to start in 7th through 12th gears and shift to a desired continuous operation gear of 11th or 12th.
Mack has also launched Mack Trucks Configurator, an online tool that allows customers to build and customize Mack Granite and Granite HD models.
“The Mack Trucks Configurator presents customers with recommended specs for seven Granite applications, plus six more for the Granite MHD,” said Tim Wrinkle, Mack construction product manager. “Customers can then tailor several spec options to create a truck that best fits their specific needs.”
Once complete, customers have the option to send the configuration to their local Mack dealer for additional information and quoting. The shared configuration is also streamlined with Mack’s sales quote and ordering system, allowing customers to easily receive a quote on a new Mack Granite or Granite MHD model quicker than ever.
Mack also announced a new loyalty reward program for National Ready Mixed Concrete Association members who purchase Mack Granite models. The Let’s Build! Mack Trucks Parts and Service Loyalty Reward Program offers NRMCA members a $1,000 parts and service reward for Mack Granite models purchased between Jan. 12, 2018 through June 30, 2018. Customers are eligible to receive the reward for up to 10 Granite models at participating Mack dealers.
“It’s good news for our construction customers that the industry is continuing to expand, and we wanted to reward them with yet another benefit to doing business with Mack Trucks,” said Jonathan Randall, Mack Trucks senior vice president of sales and marketing. “Customers require ongoing support once they purchase a vehicle, and this loyalty reward program enables them to improve their ROI by saving money on Mack Granite parts and service.”
