They started production in 1964 and built their excavators under a licensing agreement with German manufacturer O&K (Orenstein & Koppel), with the first model produced being the RH5.
In the late 1970’s the company began to develop their own machines. The BH range were loosely based around the O&K technology.
These models started with the BH45 and BH70 machines which were essentially modified versions of the O&K RH4 and RH6 machines.
By the early 1980’s the company produced a range of five tracked excavators ranging from the 6.2-tonne BH30, the BH40, the BH50, the BH80, to the 27-tonne BH110.
In certain regions the machines were marketed under trade names of Nikko-O&K, or just simply as Nikko machines.
They weren't a bad excavator, but they lacked service and spares backup and JSW gave away the manufacture of excavators by the late 1980's, to concentrate on steel production.
There's still the one odd one running in Australia.
