“This investment strategy will help ensure we continue to deliver Mack’s durability through a more efficient, integrated and modern manufacturing operation.”

Plant enhancements will include a 75,000 square-foot expansion to improve material handling and flow; new manufacturing IT systems; equipment and tooling; and a new building for conducting quality audits on completed vehicles.

Chassis pre-assembly work currently completed by Westport Axle in Breinigsville, Pennsylvania, will be moved into the Mack plant. Westport will continue several other critical support operations for Mack.

The investment plan includes around US$12m in projects which will be completed during the next three years, but were included in the US$26m upgrade announced in 2014.

Mack’s Lehigh Valley Operations produced its first trucks in 1975. Today, the 1 million-square foot facility assembles all Mack trucks built for the North American market and export. 

Mack is one of North America’s largest producers of heavy-duty trucks, with the company’s vehicles sold and serviced in more than 45 countries.

Mack trucks and diesel engines sold in North America are assembled in the US.

Mack Trucks is part of the Volvo Group.
