Is it difficult to open a gantry crane at the dock?

Gantry crane drivers work hard, with three shifts a day, 8 hours per shift, 365 days a year. For gantry crane drivers working at high altitude, eating and drinking water are big problems. They can only carry some high-calorie snacks with them every day, and eat a few bites when they are hungry.

The work of the gantry crane driver belongs to aerial work, and it is very dangerous to work at an altitude of tens of meters every day. However, every job needs corresponding personnel to work in order to maintain normal social operation, and so does the high-risk job of gantry crane driver. It is because of their existence that we can see the high-rise buildings and office buildings that have sprung up in big cities.
