What are the characteristics of "heavy duty screw jack lift systems for theatre stage lifts"?

2. Must be with brake motor for the gear motors.
3. These screw jacks are travelling nut version with rotating spindle in combination with a running nut.
4. Loading nut with short safety nut are recommended.

What is the Rotating Screw Jack System? 
Rotating Screw Jack System: The lifting nuts translate. Clearance under the bottom mounting plane of the jack body is not required but allowance must be made in the lifting platen design to allow the platen to pass over or past the lifting screw.
Rotating Screw Jack: The lead screw is fixed to the worm wheel so rotation of the worm wheel causes rotation of the lead screw thus translating the nut along the lead screw when the nut is attached to the load.

Which types of screw jack is self-locking? Single start trapezoidal type screws are typically self locking. Screw jacks are often found on the underside corners of equipment or conveyors, supporting the load and allowing for equipment height to be adjusted. Precise positioning, self locking and uniform lifting speeds are all characteristics achieved by utilizing a screw jacks system.

The screw jack can be provided with a safety nut attached to the main nut in such a way that the safety nut can accommodate the load in the event of failure.
