Mack Trucks is investing $26m to upgrade its Macungie Cab & Vehicle Assembly facility in Pennsylvania including an overhaul of its sub-assembly and material handling processes to make the delivery of trucks to customers more efficient.

The truckmaker, which his part of the Volvo Group, will also be installing new equipment to improve post-production inspection and testing of finished vehicles.

“Along with a product line-up and a dealer network that have never been stronger, this latest significant investment in our facilities sends a clear message that Mack is poised to grow our business,” said Stephen Roy, president of Mack Trucks North American Sales & Marketing.

Located just outside Allentown, the plant has three cab and two chassis assembly lines, a truck modification centre and an engine line. The company distributes trucks to 45 countries around the world.
