Target Industry Solutions
Proven Performance




Synchronized Stage Lift System (Europe)
A theater required 4 linked screw jacks to lift a 10-ton platform with absolute synchronization and a fail-safe self-locking mechanism. Solution: Designed a system using 4 Changyulong SWL100 units with a central drive and mechanical link shafts.
▪100% precision synchronization achieved. ▪The system operates with zero back-driving, ensuring safety for performers.
Technical FAQ
- How does cycloidal handle shock loads better than helical?Helical gear teeth contact is limited to 1-2 teeth, while cycloidal distributes load across multiple pins, providing superior overload protection.
