Understanding of the tower crane electrical equipment and security devices

 

     Production at the site, we can often see the shadow of the tower crane. Use tower crane production has penetrated the building, then as a spectator, tower crane know? Here's a detailed electrical equipment and safety devices under the tower machine, what does? It can be divided into: limit switches (stopper); overload fuse; buffer stopper device; rope anti-off devices; anemometer; emergency safety switch; security audio signal. First is the tower crane electrical equipment including cable reel - central collector ring motor, the operation of the motor with electrical appliances. Like a controller, master controller, contactors and relays. Protection appliances are important electrical tower equipment. Tower crane safety device is essential on production safety is the most important. It can be divided into: limit switches; overload fuse; buffer stopper device; rope anti-off devices; anemometer; emergency safety switch; security audio signal. For now, the tower crane safety devices have been more perfect.
