Mack Trucks is continuing to see high demand for its rigs.
The truckmaker produced 2,687 rigs in May, up almost 60 percent over the same month a year ago, the company reported Monday.
Mack, a division of Sweden’s Volvo AB, is headquartered in Greensboro, N.C., and produces all rigs at its Lower Macungie Township plant, which employs roughly 1,700 workers.
The company has produced 12,191 rigs through May, up 56 percent compared with the same span in 2011.
