Mack’s Macungie plant marks 40 year anniversary

Nov. 19, 2015
First Mack highway truck assembled at the Lehigh Valley Operations manufacturing facility – an F711ST model – rolled off its production line on Nov. 19, 1975. Today all Mack trucks are assembled at the facility.

Mack Trucks noted that its Lehigh Valley Operations manufacturing facility Mack, located in Lower Macungie Township, PA, crossed the four-decade mark on Nov. 19 this year.

Site preparation for the one million square-foot facility began in May 1974, with construction completed in less than one year. The plant’s layout was designed in-house by Mack employees, without the help of outside consultants, to maximize manufacturing efficiency and flexibility.

With a 700-strong workforce, the first trucks produced at Mack Lehigh Valley Operations included Mack CF model fire apparatus, Mack F model cabover highway trucks and off-highway models like the Mack M series mining trucks and the Mack Pack articulated bottom dump.

In conjunction with this anniversary mark, Mack said it is changing the name of the facility from Macungie Cab & Vehicle Assembly to Mack Lehigh Valley Operations, highlighting the site’s regional impact.

“This new name identifies our heritage, but also more accurately captures our operational footprint and the contributions of our employees who live throughout the region,” said Wade Watson, VP and GM of Mack Lehigh Valley Operations. “Although we are celebrating four decades of success at our plant, we have been revitalizing the facility with innovative systems and tools that already give our operation a very modern feel, and we are not yet complete with our updates.”
