Consolidate the foundation with heart efficient life change

When the elevator exceeds the standard limit speed, the speed limiter cuts off the safety circuit to ensure that the elevator stops running. When the elevator exceeds the standard speed, the safety gear is actuated by the governor in conjunction with the speed limiter to ensure that the elevator is safely stopped. The hydraulic buffer can absorb the abnormal impact energy of the elevator to the greatest degree, ensuring the safety of the elevator passengers.

New generation permanent magnet synchronous traction machine

The new generation permanent magnet synchronous gearless traction machine uses rare earth materials to fully integrate coaxi-al transmission technology, digital frequency conversion technol-ogy,and group computer combined control technology. The operating cost is low and the energy dissipation is low.

Door machine system

The door machine system integrates permanent magnet technol-ogy, variable frequency control and synchronous belt transmis-sion. It runs smoothly, efficiently, and with low noise. It has independent intellectual property rights, and is independently designed and manufactured. lts technical level has reached the international advanced level.

High precision intellectually creates a bright future

Micro-computer group supervision system

Peak-hour running mode: It satisfies peak-hour running requirements in public occasions such as office building etc. Even running mode: lt applies minimum time distribution principle with rational and prompt elevator response. ldle running mode: At idle times. the elevators are evenly distributed in the designated zones. It ensures that it promptly responds outer calling in time.

Highly integrated, dual 32-bit S intelligent full computer control system makes elevator data processing faster; and the classic combination of a dedicated all-digital vector IP inverter, through the full closed-loop speed feedback adjustment, makes the elevator operation exceptionally stable With comfort.

Safety first

Light curtain door protection system

A light screen barrier is formed at the elevator entrance, and 94 infrared beams are protected. lt can react sensitively to any person or object enter-ing its detection plane. lt has high safety perfor-mance and can quickly restart the door opener and clamp-proof device.

Elevator car accidental movement protection

When the elevator is in the flat position and the door opens, if the elevator moves unexpectedly, UCMP safety device immediately starts protection, stops the elevator operation, and prevents passengers from being pinched by the car

Anti-earthquake function

The use of advanced elevator seismic perception early warning system combined with elevator control system can make the elevator effectively enter the controloperation state before or when the earthquake occurs,make the elevator open the door on the nearestfloor, release the passengers in the elevator,maximize the safety of passengers and ensure the elevator equipment. No damage

Power-failure emergency device

If there is a sudden power failure during the opera-tion of the elevator, it will automatically switch to the standby power supply to keep the elevator running to the nearestfloor to ensure that passengers leave the elevator safely.
