Screw jack handwheel is very popular for all kinds of applications. So when to use it?
1. 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.
2. Light load, low duty cycle, low-speed application.
3. Intermittent positioning applications.
