MWD series hydraulic excavator for coal mines: an intelligent tool for underground operations（haoyun）

The editor of Shandong Haoyun Heavy Industry Machinery Co., Ltd. will discuss the MWD series hydraulic excavator for coal mines: an intelligent tool for underground operations.

Safety and environmental performance are prominent advantages of the MWD series. The whole machine adopts an explosion-proof electrical system, and from the button to the motor, it meets the safety standards of coal mines, effectively preventing the safety risks of flammable and explosive gases such as underground gas. In terms of power, the pure electric hydraulic system replaces traditional diesel engines, not only eliminating exhaust pollution, but also controlling operating noise at an extremely low level, significantly improving the underground working environment. The hydraulic system adopts high-pressure design and is equipped with explosion-proof motors with rated power.

The intelligent upgrade has become a new highlight of the MWD series. Real time monitoring of equipment operation status through sensors enables fault warning and preventive maintenance, significantly reducing downtime. These technological innovations have elevated the MWD series to new heights of operational safety and economy while meeting safety standards.

Under the promotion of the national “dual carbon” strategy, the green attributes of Haoyun Heavy Industry’s MWD series have become increasingly prominent. The electric power system has low energy consumption and high efficiency, which can significantly improve the speed of coal mine excavation. Its modular design not only facilitates maintenance and replacement of components, but also reserves space for future technological upgrades. At present, this series of products has been widely used in underground excavation, tunnel repair and other scenarios.

The development process of MWD series hydraulic excavators for coal mines, from manual excavation to mechanized operation, reflects the technological breakthroughs in China’s mining equipment manufacturing. With the deep integration of automation and unmanned technology, this underground operation tool is driving coal mining towards a safer, more efficient, and more environmentally friendly direction, providing solid equipment support for the high-quality development of the energy industry.
