Elevator Equipment Corporation (EECO) was founded in 1946 as Elevator Equipment Company and manufactured and sold single func ... tion valves and jack units. Through the years EECO also developed and began manufacturing unit valves, power units, switches, and other components used in the installation of hydraulic elevators. The industry standard UV-5 Series and UV-7B Series hydraulic unit valves are manufactured and assembled in our original plant in California, where jack units, Doors & Entrances, hatchway switches, car slings, platforms, and other various support products are also produced. Since it's beginnings in Los Angeles, California, EECO has expanded into facilities in Richmond, Indiana. Now, our modern 140,000 square foot Indiana plant manufactures jacks, power units, car slings and platforms, and other mechanical and structural items, including the new UV-4R control valve for residential/LULA and low flow applications. EECO is pleased to list all major elevator companies as customers.
