Mack Trucks will continue its longstanding support of the Concrete Industry Management (CIM) program with the donation of a 2021 Mack Granite mixer for the annual CIM Auction June 9 during World of Concrete 2021 at the Las Vegas Convention Center.
Bids on the Mack Granite will be accepted during the silent and live auctions and all proceeds will benefit the CIM program’s mission to develop the next generation of leaders within the concrete industry.
“Mack Trucks is proud to again support the CIM program and the development of future industry professionals,” said Tim Wrinkle, Mack construction product manager. “As a leader in the construction segment, Mack understands the valuable skills and insights that CIM’s programs offer students, creating well-rounded leaders and workers, ready for the demanding and competitive concrete industry.”
The donated Mack Granite Axle Forward model bridge formula mixer is powered by a 375-horsepower Mack MP7-395C engine, delivering 1,360 lb.-ft. of torque. The engine is paired with a 14-speed Mack mDRIVE HD automated manual transmission with ultra-low ratio creeper gears and Mack front and rear axles. Paired with the Mack Granite and rugged Mack Cornerstone chassis is a McNeilus FLEX Controls Bridgemaster Mixer featuring an 11-cubic-yard M80 Series drum, donated by McNeilus.
Mack GuardDogConnect, Mack’s integrated telematics solution, is standard on the Granite model and allows customers to make unlimited driver-activated software and parameter updates, also standard through the Mack Over The Air remote programming solution, improving uptime and simplifying the update process.
The Mack Granite model is backed by a comprehensive 60-month/250,000-mile Mack Engine Plan 2 extended warranty, and the auctioned Granite model will be delivered free to anywhere in the contiguous U.S. Additionally, all Federal Excise Tax will be paid.
“Once again Mack Trucks and McNeilus have demonstrated their industry leadership by donating the signature item for the 2021 CIM Auction,” said Ben Robuck, CIM Auction Committee Chairman. “Their continued support speaks volumes to their commitment to the concrete industry and the importance these leading companies place on the CIM program's role in developing the future leaders of our industry. This mixer truck will help ensure a successful CIM Auction at the 2021 World of Concrete.”
The annual auction is the primary fundraiser for CIM programs, supporting the current programs and helping fund scholarships. In February 2020, Mack donated a 2019 model to the 15th annual CIM auction.
The business intensive CIM program awards students a four-year Bachelor of Science degree in Concrete Industry Management and is currently offered at Middle Tennessee State University, New Jersey Institute of Technology, California State University – Chico, Texas State University and South Dakota State University. CIM also offers an Executive MBA program for individuals with industry experience. Today, nearly 1,400 graduates of the CIM program work in the industry.
