Energy Mfg. Co. Inc./Williams Machine and Tool

Founded in 1944, Energy Manufacturing Company, Inc. is headquartered in Monticello, Iowa, USA, with over 115,000 square feet (10,684 m²) dedicated to the world-class design and manufacture of hydraulic cylinders and fluid power components, and systems.

Williams occupies a rich place in history in the Nation's heartland. The story begins in 1938 with an enterprising man, David Williams, venturing out to start his own job shop in a modest garage in Omaha, Nebraska. Thus, Williams Machine & Tool was born, and the rest is the quintessential American success story of ingenuity, hard work, and determination. Williams launched its first hydraulic pump design in 1948. By the 1970s, the company produced piston pump/reservoir combinations for approximately 80% of the light to medium duty farm trucks on the road. Ever since, the company has grown steadily into one of Americas leading specialty manufacturers of a wide range of hydraulic pumps, power units and related components and systems for original equipment manufacturers (OEMs) throughout the United States and Canada.
