Mack Trucks, Inc. today announced that the company will move forward with its previously announced plan to consolidate production of its entire product line at its assembly facility in Macungie, Pennsylvania.

The plan involves transferring assembly of Mack highway vehicles from the plant in Virginia’s New River Valley to Macungie, where Mack’s construction and refuse trucks are assembled, to take advantage of efficiencies arising from consolidated assembly, and to create a brand-unique environment for Mack customers.

The company expects to begin the transfer in September 2009 and complete it by the end of November 2009, during which period there will be a gradual production ramp-down in the NRV and a corresponding ramp-up in Macungie.

Due to the prevailing market conditions, the company expects that rather than adding personnel in Macungie, it will instead support the increased production by reducing the number of down weeks. The transfer is expected to result in an employment reduction at the NRV plant, which will continue to produce Volvo Trucks North America’s entire product range, but it is too early to quantify the impact.
