[0002] The tower crane switch box, also known as the tower crane control box or tower crane electric control box, is the core electrical control equipment of the tower crane (tower crane). It is responsible for managing and controlling all electrical operations of the tower crane to ensure that the tower crane can perform lifting operations safely and efficiently.

[0003] During the use of tower crane switch box, the safety factor and stability of its circuit are more important. Most existing tower crane switch boxes have the following shortcomings:

[0004] The existing switch box is not convenient for distributing electric energy to different circuits or devices when in use, and cannot ensure the reasonable distribution and use of electric energy. At the same time, when the short circuit current increases rapidly, it cannot automatically cut off the power supply, and the circuit cannot be controlled manually or automatically.

[0005] In response to the above problems, this utility model document proposes a tower crane switch box with fault diagnosis and early warning functions. Utility Model Content

[0006] The utility model provides a tower crane switch box with a fault diagnosis and early warning function, which solves the shortcomings of the prior art, such as the inconvenience in distributing electric energy to different circuits or equipment, the inability to ensure the reasonable distribution and use of electric energy, and the inability to automatically cut off the power supply when the short-circuit current increases rapidly, and the inability to control the on and off of the circuit manually or automatically.

[0007] The utility model provides the following technical solutions:

When the temperature or humidity exceeds the preset safety range, the sensor will send a signal. The buzzer alarm and the warning light are installed on the top of the box to receive signals from the temperature sensor and the humidity sensor. Once an abnormality is detected, the buzzer alarm will sound and the warning light will flash to remind the operator to pay attention and take corresponding measures, which is conducive to achieving fault diagnosis and early warning functions and improving safety of use.
