The Electro-Lift separator screen changing system from Midwestern Industries is ergonomically designed and electrically powered. Engineered with a 120-volt, sealed gear-driven system, operation is as simple as plugging into an outlet and pressing a switch. The systems are adaptable to fit a variety of different frame deck configurations. Electro-Lift is mounted independently to the frame so there is no need for it to be locked out when working under it with your hands. The sealed gear-driven system eliminates the need for greasing, making it environmentally friendly. 330-837-4203; www.midwesternmind.com
