The data displayed on the screen of monorail crane is 0.

If the data on the monorail crane screen is 0, there may be several reasons:

1. Poor connection of power supply or signal line: check whether the power supply and signal line are firmly connected and whether there is short circuit or poor contact.

2. Data transmission failure: check whether the data transmission line is normal and whether the data transmission is disturbed or interrupted.

3. Failure of the screen itself: Check whether the screen works normally, whether there is damage or other problems.

4. Controller failure: Check whether the controller works normally, and whether there is any failure or other problems.

If the above methods fail to solve the problem, it is recommended to contact the relevant manufacturers or technical support personnel for repair or replacement of parts. At the same time, when installing and operating the monorail crane screen, it is also necessary to comply with the relevant safety regulations and operating instructions to ensure personal and equipment safety.
