What do crane mechanical design engineers mainly do?

Mechanical engineers are proficient in repair. If there is any incurable disease that others can't get, you can be an elite in machinery. There are two aspects in crane industry: production and installation. Production is to make finished products, and installation is the business that salesmen run out of the factory. Where to buy a crane, it can be installed and used normally. Installation is a dangerous job, and so is the work of mechanics. The mechanical elite became mechanical engineers.

Hope to adopt. Thank you.
