Headquartered in Tulsa, Oklahoma, TWG is comprised of six distinct companies that manufacture industry-specific winches, hoists, gear drives, swing drives, auger drives, slewing ring bearings, hydraulic pump and electronic monitoring solutions for energy, infrastructure and recovery markets worldwide. Collectively, these companies serve global leaders in the mobile crane, oil field, towing, government, heavy hauling, utility, construction, forestry, mining, refuse, and aerial work platform markets.

TWG is a part of Dover Corporation, a multi-billion dollar global producer of innovative equipment, specialty systems and value-added services for the industrial products, fluid management, engineered systems and electronic technology markets. Dover is traded on the New York Stock Exchange under the symbol DOV.

TWG acquired Pullmaster Winch Corporation, a Canadian company and leading manufacturer of planetary hydraulic winches. This complementary add-on brought leadership in several market niches not served by TWI, such as commercial fishing, logging, and marine dredging. The previous owner of this privately held business faced many of the same issues most owners face in preparing for retirement. The courting process between Dover and Pullmaster took place over several years but Dover was finally selected as the best choice to continue to build upon the strong legacy of Pullmaster.

In March 2008, TWG acquired LANTEC Winch & Gear, its second Canadian-based company. As a leading manufacturer of hydraulic winches, hoists and gear reducers for the oil and gas, infrastructure and marine markets, LANTEC further broadened TWG’s collective range of winch products and expanded its market presence.
