In recent years, the rapid development of large-tonnage trucks and dump trucks has provided a good market for large-tonne earth-moving machinery. However, at present, large-tonnage excavators in the domestic market are almost universally dominated by foreign brands. In order to meet the needs of the market, Haidou Construction Machinery Division combined its own characteristics, through research and development personnel to conduct multiple investigations and in-depth solutions to a number of technical problems. The HW450 mining excavator was successfully manufactured.
It is reported that the Haidou Construction Machinery Division will carry out type experiments and reliability tests on the prototype HW450 mine excavators that have been successfully tested to verify its performance. (This article comes from China National Heavy Duty Truck)
