Product Description:
Electric screw jack lifting system is widely application for theatre stage synchronous lifting platform,
which structures include multiple screw jacks, miter gearboxes, flexible couplings and line shaftings. Compared with hydraulic lifting platfrom or electric cylinder actuators lifting platfrom, screw jack lifting system has self-locking feature without brake or locking mechanism, precisely positioning, full synchronization, motor driven, easy installation and operation, maintenance free.
