Passenger hoist overload protector commonly known as passenger hoist overload protector elevator overload limiter is corrosion-resistant and durable. It consists of one main engine plus two sensing pins. If it is a double-cage passenger hoist, it is two main machines plus four sensing pins. The diameter is divided into 35-axis sensing pins and 40-axis sensing pins. The sensor pin of the overload protector of the passenger hoist, the physical display is as follows:
Passenger hoist overload protection device is coming from the sensor signal by the limiter summing amplifier, A / D converter, microcontroller operation, when the weight lifting cage reaches or exceeds the set value, the corresponding relay respectively within the limiter actions connected with the elevator control system to ensure lift safe and reliable.
1. Strong anti-torsion and anti-bending ability.
2. Easy to assemble with related load-bearing parts and easy to use.
3. The internal connection of the interface fixed with the nut is not easy to fall off, and there is no need to worry about the influence of electromagnetic on the sensing in industrial occasions.
