Since the owner knows about Konecranes and Demag, I'll mention some other brands. I won't mention the manufacturers that have been merged by Konecranes (brands such as SWF, etc.). The vast majority are French and German, and there are 2 Spanish Konecranes merged by too many manufacturers )

Francorchid Cranes (Germany)

German STAHL Cranes

CM Group of the United States (currently the largest manufacturer of factory cranes in North America)

Japan has no famous crane manufacturers. Due to outdated design specifications and other reasons, Japanese bridge crane manufacturers are confined to Japan

Taiwanese and South Korean crane manufacturers, both of which are currently out of the picture

Manitowoc manitowoccranes

Scania

I won't list any other cranes such as automotive tire cranes, (mostly) I don't know, I only know about bridge cranes).
