Installation Instructions

Description.
1. Basic form: The nut (worm gear) rotates the screw for upward and downward motion, typical for elevator installations. Note: Lifting induces rotational force in the screw, necessitating anti-rotation measures. 2. Stop-rotation structure: Suitable for scenarios without connection at the top and where preventing rotation is essential. 3. To extend stroke within confined spaces, consider a movable nut structure (custom-designed and manufactured with the screw). In this setup, the screw rotates while the nut moves. If the travel extends significantly, support at the shaft end ensures effective transmission.
If the travel distance is extensive, support at the shaft's end is essential to achieve optimal transmission performance.
