Shanghai guzuo SWL series trapezoidal screw lifter is a vertical worm gear lifting mechanism

with compact integrated structure. Adopting worm gear transmission and trapezoidal screw structure,

this mechanical screw jack features reliable self-locking performance, strong load capacity and stable

lifting movement. It can realize linear lifting, pushing, tilting and height adjustment without hydraulic

and pneumatic system. Widely used for static load and low-frequency lifting working conditions

in various industrial mechanical equipment.

Main Features

• Mechanical Self-locking: Worm and worm wheel structure provides excellent self-locking function to keep the load fixed without slipping.

• Trapezoidal Screw Design: Thickened trapezoidal screw ensures strong bearing capacity, wear resistance and stable static support performance.

• Compact Integrated Structure: Small overall size, simple installation and no complicated auxiliary transmission parts.

• Manual & Electric Drive: Support handwheel manual operation and motor electric driving for diverse control demands.

• Flexible Combination Application: Multiple lifters can be combined to achieve synchronous lifting for large platform equipment.

• High Safety Performance: Stable lifting speed, low vibration and no impact, suitable for slow and steady height adjustment.

Application Scope

Precautions

• Not suitable for high-frequency continuous reciprocating movement to avoid screw wear and heat accumulation.

• Avoid overload and eccentric load during operation to prevent screw bending and gear damage.

• Regularly fill lubricating grease to reduce friction and extend service life of worm gear and screw.
