Flexible Transmission Column Lift, awarded a national invention patent in 2013 and is an innovative rigid link chain system designed for both vertical lifting and horizontal push-pull applications.

Working Principle
The Column Lift employs a unique mechanism that converts the horizontal motion of chain links into a vertically rigid, unidirectional structure through its drive housing. This mechanism allows for precise, smooth, and controllable vertical lifting. Each unit is capable of handling a maximum dynamic load of 60 tons, with a stroke length of up to 16 meters.

Key Technical Advantages
1. Safe, Stable, and Reliable
• Engineered with exceptional stability and rigidity, it complies with national mechanical design standards.
• Successfully implemented in high-profile projects such as the 2022 Beijing Winter Olympics and Paralympics, Expo 2019 Beijing Horticulture Exhibition, as well as national theatres, international conference centers, and large-scale provincial venues.
2. Compact and Efficient Design
• The compact drive housing integrates chain links with an aluminum alloy storage tube.
• Available in single-layer, double-layer and triple-layer configurations, it meets requirements for space-saving and long-stroke applications.
3. Accurate Positioning with High Repeatability
• Achieves positioning and synchronization accuracy within ±1mm, allowing precise stops at any point within the stroke range.
4. Flexible and Modular Configuration
• The modular design enables flexible layouts, helping reduce infrastructure costs.
5. Economical and Durable
• Requires only regular lubrication, ensuring long-term durability and reducing maintenance frequency.
6. Environmentally Friendly and Quiet
• Operates quietly, with noise levels under 50 dBA at a distance of 1.5 meters during single-machine operation at rated speed and full load.
These technological advantages make the Column Lift a leading product in the industry, widely used across multiple sectors, providing reliable technical support and services.
