We manufacture four types of 4m³ excavators, including WK-4A, WK-4B, WK-4C and WK-4D excavators. Our WK-4C excavators are the most advanced, and will gradually replace the WK-4A model. They are widely used in metallurgy and coal in middle and small opencast mines for excavating and stripping works, as well as in petroleum, chemical, hydropower, construction, and earth/stone work engineering.

We have established a new production base in the Binhai New Area of Tianjin to facilitate the transportation and export of large-sized equipment. Our second wheel production line is currently under construction. We have also established production lines for wheels, axles and wheel sets for use at speeds above 200 km/h.
We are now turning our focus to international markets which we are certain can benefit from our high quality products and service. As we are constantly innovating and improving, we have no doubt that we will meet and even exceed our customers’ expectations.
