Elevator Emergency Leveling Device For Safety Features, Functions & Compliance Standards

SN-ARD-3P ARD is a new generation elevator system rescue device. In the event of a power outage, it ensures that the elevator reaches the nearest or bottom floor safely and opens the elevator doors securely. It is also suitable for situations where there are power issues with the elevator itself. Based on intelligent microprocessor design, the ARD can be installed on any elevator control system. Equipped with sealed maintenance-free lead-acid batteries. Easy to install, ensuring elevator safety leveling. When there is a power outage or a problem with the elevator power system, the ARD will activate within seconds. If the elevator stops at a floor level, the ARD simply opens the elevator door. If the elevator stops between two floors, the ARD will start the motor and use less current to bring the elevator to the nearest or bottom floor as instructed, and then open the elevator doors. After completing the operation and safely reaching the destination, the ARD will shut down automatically. 

Product Functions

1.Fully automated operation

Monitoring and standby status and emergency rescue processes are automatically completed under microcomputer control, without the need for manual intervention.

2.Safe and reliable

Uses electrical interlock automatic feedback, eliminating the need for the elevator main power to be connected to this device. The control switch between the device and the power supply is fully isolated statically, ensuring normal operation of the elevator and signal acquisition during emergency processes, and safe operation during rescue processes. During elevator maintenance, this device refuses to operate.

3.Strong universality

Adopts flexible and varied interface schemes, compatible with elevators of different brands and models. Even if your elevator is upgraded, simple adjustments are all that's needed for compatibility. The button adjustment function uses online rewritable memory to store various parameters that need adjustment, making debugging simple, intuitive, and reliable.

FAQ
1. Are the elevator wire ropes durable?
The elevator wire rope has special provisions and requirements. Configuration is not only for wire rope and rated load, but also considered the size of the traction, as a result, the tensile strength of wire rope is greater than the weight of the lift. The safety factor is equipped with more than four wire rope. So it won’t break at the same time.
2. Is it dangerous for power failure suddenly during the elevator running?
If it occurs, the elevator will automatically stop due to the electrical and mechanical safety device. In case of power failure,elevator brakes will automatically taken. In addition, the power supply departments such as planned outage, prior notice are also operating.
3. Will us be hurt when it closed suddenly?
In the closing process, if people touch the hall door, the door of elevator will automatically restart without any danger. With anti clamping switch, once the gate touched, this switching action make the elevator unable to be closed and even reopened. In addition, closing force is also available here.
4. How the elevator running?
Elevators are operated with a counterweight wire rope through the (tractor) traction drive, making ups and downs on the guide rail.
5. Is the escalator installation complicated?
We believe the functions of an escalator are not necessarily proportional to the operation complexity. Therefore, escalators designed by us apply an integrated structure, so that the equipment is more precise and more efficient and allows easier and more convenient commissioning.
6. Do you have any cerifications?
Yes, we do with ISO9001 / CCC / CE Certificates for u.
