Mini Manual Screw Jack With Handwheel

A handwheel is a convenient solution for manually operating a jack when using machine screw jacks in intermittent positioning applications. We offer hand wheels in a variety of diameters.  Their specific selection is dependent on input torque requirements. Cast iron is standard, stainless steel and bake lite material is available. Handwheels do not include a brake and therefore are not for use with ball screw jacks. They are recommended for self-locking jacks and actuators and can be mounted directly to the jack input shaft.

Manual Operated Screw Jacks by hand wheel or hand crack. Screw Jack Actuator can be both Electric Driven and Manual operated. When you manually operated screw jacks, you can use hand wheel or hand crack. 
So when to use hand wheel screw jack?
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 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, short stroke, low-speed application.
3. Intermittent positioning applications

Acme screw jack since ball screw jack is not self-locking and hand wheels do not include a brake.
You can digital position indicators if you need more precise position display. It can measure the rotations of the input shaft and display the corresponding position in the digital counter window. The display value per input shaft revolution is variable and is achieved through a series of gear reductions configured to accommodate different worm gear screw jack ratios, screw pitch, and travel length. Easy installation to existing actuators. All hand wheels are bored, keyed, and set-screw drilled to the proper dimensions.
