Lewis Equipment Co. Inc. on Sept. 18 filed for Chapter 11 in U.S. Bankruptcy Court, Northern District of Texas. The 24-year-old Grand Prairie, Texas.-based crane-and-lift supplier listed over $100 million in assets and liabilities. Calls to Lewis executives were not returned. The company is the exclusive North American dealer for China-made Yongmao SunCrane tower cranes, Zoomlion mobile- and-crawler cranes and Hercules elevators. Lewis bought Verticon’s New Zealand tower- crane and hoist division for $11.75 million in late 2007, as well as $33.9 million of Zoomlion truck cranes about 18 months ago. According to court records, the company has 200-plus creditors.
