what kind of material is used in making of crane and what is the making process of crane.
There are so many kinds of cranes that you need to pick one to get any kind of good answer - the tall T shaped cranes are simply welded up from tubing and barstock into modular sections that will fit on a semi trailer and be hauled to the site. Their structure shows in the photos. A boom crane with telescoping boom has to be made up of welded tube sections with bearings and hydraulic pistons inside and out. And of course, the base of a moveable crane adds a whole series of complications.
