Lifting Window System
The industrial constant force hinge group cooperates with self-lubricating multi-wedge belts to realize the vertical lifting and lowering ±0.8mm trajectory control of 120kg super large window sash. Through the Nordic -45℃ freeze-thaw cycle and the Middle East 55℃ thermal expansion dual limit test, the aerospace-grade sealed guide rail maintains IP68 waterproof and dustproof grade at an altitude of 100 meters in the hurricane area, so that the viewing curtain wall can freeze frame in the wind and rain millimeter level accuracy.
