High Technology Passenger Elevator: Smooth Start, Quick and Quiet Moving
Advanced VVVF drive ensures the elevator operates more smoothly. Superior noise control provides passengers with a peaceful riding experience. The start, acceleration, and brake curves are designed according to ergonomic theory to achieve maximum comfort. It utilizes a genuine current vector control variable frequency drive system. The permanent magnetic synchronous drive saves up to 48% in energy consumption.
High Precision Positioning Control System
Car displacement tracking technology ensures leveling safety. High-accuracy detection makes for almost perfect leveling between the car and the landing level.
Top Advanced Door Operator System
Applying advanced variable voltage and variable frequency control technology to the door operator system ensures smooth and quiet switching. The self-learning door load detector monitors variations on every floor, automatically rectifying open/shut speeds to guarantee security and reliability.
Reasonable machine room arrangement keeps sufficient maintenance space. Parts undergo rigorous reliability testing to ensure continuous stable operation. Diverse and flexible car designs make this serial passenger elevator the best choice for hotels, restaurants, office buildings, shopping centers, and residential villas.
