Electric/Mechanical Vertical Installation Lead Screw Elevator

Screw lift, SWL series worm screw lift is a basic lifting component that complies with JB/T8809-2010 (formerly JB/T8809-1998, JB/ZQ4391-86) standards. Carrying capacity of 2.5-120T. It has the advantages of compact structure, small volume, light weight, wide power source, low noise, easy installation, flexible use, multiple functions, multiple supporting forms, high reliability, and long service life.

Screw lift, also known as spiral transmission mechanism. It is mainly used to transform rotational motion into linear motion or to transform linear motion into rotational motion. There are feed screws that mainly transmit motion, such as those used in machine tool workbenches; There are also screw transmission mechanisms that adjust the relative position of parts. Screw elevators can be divided into sliding friction mechanisms and rolling friction mechanisms. The sliding screw nut mechanism has a simple structure, easy processing, low manufacturing cost, and self-locking function, but it has high friction resistance torque and low transmission efficiency. Although the ball screw nut mechanism has a complex structure, high manufacturing cost, and cannot self lock, its major advantages are low frictional resistance torque, high transmission efficiency, high precision, good system stiffness, reversible motion, and long service life. The screw elevator is composed of a worm gear reducer and a screw rod, and its reduction component is a worm gear transmission, which uses the worm gear to drive the worm wheel to achieve reduction. The worm gear is equivalent to the nut of the lifting screw, which matches the lifting screw.
