Following back-to-back announcements of two plants in North Carolina — a new axle assembly plant in Winston-Salem and the expansion of its Sanford, North Carolina, compact equipment factory — Cat will now build an excavator assembly plant in Victoria, Texas, according to the Wall Street Journal. The plant will employ more than 500 people and triple the firm’s capacity to build excavators in the United States. The 600,000-square-foot plant will begin production in mid-2012.
