 4. Lifting limit switch and traveling limit switch 

 5. Emergency stop system 

 6. Electrical protection 

    The main insulation switch, emergency stop switch, short circuit, Zero voltage protection, loss of field protection, Current overload protection, over speed protection, zero position protection
    Phase sequence protection and adopted  crane specially anti-vibration contactor etc. 

 7. Interlock device 

    It sets interlock device for the cabin  door and the other door from cabin into bridge structure, when the door is opened, the crane cannot work.
