    Cam controllers on lifting crane machines
    Cam controllers on lifting crane machines

    The cam controller realizes the forward and reverse directions of the motor through the closing sequence of its power contacts.When the cam controller is used, the electromagnetic coil of the actuator is connected to the stator line on the motor, and it is powered  on and off at the same time as the motor. The master controller is matched with the magnetic control panel to become a complete control system. The commands issued by the master controller are realized by the corresponding contactors on the magnetic control panel to start, brake and adjust the speed and reversal.The master cont ...

    Energy-saving overhead bridge crane advantage
    Energy-saving overhead bridge crane advantage

    1. The energy-saving overhead bridge crane adopts corrugated web crane, has light weight and small wheel pressure, which can reduce the stress on the steel structure workshop;2. The corrugated web has increased corrugation due to the web, and the thickness requirement is reduced, so the steel can be saved by 25% to 40%, and the manufacturing cost does not increase much;3. The corrugated web increases the reinforcing ribs and improve the stability of the web to improve the shear resistance of the section;4. The energy-saving overhead bridge crane is compact inmechanism and small on overall size ...
