An electric motor screw jack, also known as a motorized screw jack, is a mechanical device that utilizes an electric motor to convert rotary motion into linear motion. This linear motion can be used to lift, lower, push, pull, tilt, or position heavy loads with high precision and reliability. More energy-efficient than hydraulic systems, as the motor only consumes power when moving the load. Can be self-locking in the event of power loss, preventing load drop. Can be used in various applications, including lifting, pushing, pulling, and precise positioning. Multiple screw jacks can be synchronized to lift or position loads in unison.
