In the case of worm gear screw jacks used on theatre stages (lifting platforms or jacking systems that might affect personal safety, lifting elements are designed according to current regulations, and include such items as anti-drop systems (self-locking spindles and/or mechanical safety brakes as part of the drive system). The function of the synchronizing device is guaranteed, when required, by additional components.
