Mack plant has 50th anny

HAGERSTOWN, Md. — Mack Trucks paid tribute to its plant in Hagerstown, Md., where its powertrain components have been assembled since 1961.

In 1959, looking for a modern alternative to its existing facility in Plainfield, NJ, Mack decided to invest $45 million in a new one million square foot plant on 280 acres in Hagerstown.

The first Mack engine rolled off the assembly line in 1961.

As the company’s products have become more advanced over the years, so have the capabilities of the Hagerstown plant. Today, the facility is approximately 1.5 million square feet with significant upgrades, like an Engine Development Lab.

"For half a century, the heart of every Mack truck has originated in Hagerstown," said Kevin Flaherty, Mack senior vice president, U.S. and Canada. "We’ve always been an integrated manufacturer, with engines, transmissions and axles specifically designed to work together."
