Analysis of bridge crane troubleshooting methods

1 When the crane mechanical failure:
    If a fault occurs in the body or trolley carts run institutions, should emergency power;
    If a fault occurs in the lifting sector, the driver should immediately send an emergency signal:overhead gantry crane Ming alarm, loud warning notice below the staff with the control measures taken to avoid and to immediately start again on the hook lifting mechanism is controlled so that the hook can not produce free fall state;
2 crane failure there is an electrical failure or malfunction illusion:
    Turn off the start switch and the driver with emergency switch down the way;
    Ground staff with total three-phase  bridge gantry crane  off the power switch way, cutting off power to effectively control overhead crane failure events to expand, and then stop and check repairs;
    For  overhead bridge crane  illusion failure of the control, less experienced drivers, the operating handle is not exactly stay in the controller's zero due to zero as long as the operating handle complex, failure phenomenon can be avoided.
