The internal structure of a worm screw lift uses a worm gear and lead screw as the main transmission, possessing self-locking performance to ensure the reliability and safety of the equipment. One motor can drive one or more screw jacks to achieve rigid synchronization. Synchronous servo motors or encoders can control the position with a precision of 0.1mm. The worm gear structure of machine screw jack actuator amplifies torque while reducing speed, thus lifting heavy objects with very little effort. They are small in size, lightweight, easy to install, low in noise, and simple to maintain, making them suitable for various working conditions.
