Quick Tour: Mack/Volvo Hagerstown Powertrain Plant

The new Mack axle production line covers 100,000 square feet and is currently producing 128 units on each shift.

Long-time Hagerstown production worker Dan Dawson details just what goes into machining a Mack axle.

The Haggerstown plant develops and assembles diesel engines and other major components for Mack trucks, which are built at the company’s cab and vehicle assembly plant in Macungie, Pa.

The new Mack drive-axle assembly line uses automated guided vehicles to move axle housings along the production process.

One of the neat things about having an endearing corporate mascot is there's no limit to the type of message it can deliver.
