Aluminum Hand Wheel Used in Manual Jack Screw Lift Tables

Aluminum Hand Wheel Used in Manual Jack Screw Lift Tables. Handwheel for the emergency adjustment and manual adjustment of worm gear screw jacks or systems. Safety handwheels decouple themselves to prevent turning with the spindle. Standstill of the handwheel is guaranteed only up to medium speeds. In case of power failure, screw jacks can be moved manually via a handwheel. To do this, one input shaft shall be available on the screw jack for the connection of the handwheel. If a brake motor is used, the brake shall be un-clamped firstly, so to allow for movement. Light load, low duty cycle, low-speed application. Intermittent positioning applications. Our standard jacks use trapezoidal screw and have self-locking function which is very safe for manually operated by hand. We have different models for your selection, our machine screw jack is the most cost-effective selection for this application.
