What are the six major safety devices of bridge cranes

1. Overloading operation of load limiters is an important cause of frequent accidents in bridge cranes, and the use of overload protection devices can prevent accidents from occurring.

2. There are two types of limiters, one is the upward limit position limiter and the lower limit position limiter, which protect the safe operation of the lifting mechanism, and the other is the operation limit position limiter, which restricts the operation mechanism.

3. The buffer absorbs the operation of the crane trolley and reduces impact.

4. The running speed of modern bridge cranes is constantly increasing, and several machines often work on the same track at the same time. To prevent collision between bridge cranes, anti-collision devices are installed on the bridge crane

5. Anti deviation device

Due to manufacturing and installation deviations of the wheels, as well as deviations in the transmission mechanism, the operation of bridge cranes is often transferred to machinery.

6. Other safety protection devices: 1) Electrical equipment on the bridge must be equipped with rain covers. 2) The single main beam bridge crane is equipped with anti overturning safety hooks to ensure that the trolley does not overturn and needs maintenance Work is very safe.
