In what environment is the cantilever crane more convenient to use?

What kind of lifting environment is the cantilever crane mainly used in? First of all, among the numerous lifting equipment or hoisting machinery, the cantilever crane should be very extensive, so in what kind of environment they are produced more Suitable?

We first know that the use of cranes is mainly in some relatively fixed lifting environments or under relatively harsh conditions, such as some ports or under conditions where the tonnage of objects to be lifted is very large, and there are also some car repairs. For factories, etc., the tonnage of the objects to be lifted is large, and their bodies are also very large, so some cranes are needed for lifting and lifting operations.
