What certificate does the gantry need?
The problem is not comprehensive! What kind of aspect do you ask for the gantry crane? Is the operation? service? installation? Or manufacturing ah?
You can not use that card in the gantry hanging! Although all special equipment, but special equipment is not common, are to have a special certificate
You in the end is to drive gantry crane? Or repair? Or is it installed? Or manufacturing ah? These documents are not the same!
