The editor of Shandong Haoyun Heavy Industry Machinery Co., Ltd. briefly analyzes the important role and advantages of roadway repair machines in coal mines
The coal mine roadway repair machine is a multifunctional equipment independently developed by Shanzhong Heavy Industry.

The Shandong Haoyun Heavy Industry roadway repair machine is mainly used for coal roadway and all rock roadway, and can perform maintenance work such as crushing, excavation, loading, and leveling of roadway roof, floor, and side walls.

At the same time, it can also crush large rocks and coal blocks, facilitating subsequent transportation.

This equipment has multiple functions such as excavation, side digging, flipping, rock breaking, loading, and lifting, and can complete the entire process of tunnel repair.

The device has a compact structure and is suitable for narrow and low working surfaces.

The overall layout of the machine is reasonable and easy to maintain. The protective covers of the oil pump and control valve can be fully opened for easy inspection and maintenance. It is fully controlled by a hydraulic system, with a reasonable pipeline layout and high safety and stability.

Shandong Haoyun Heavy Industry’s roadway repair machine equipment has low energy consumption. Through load sensitive variable system and proportional pilot integrated control, the system’s work efficiency has been improved, and energy consumption and power loss have been reduced.

The digging bucket and breaking hammer can be flexibly interchanged, suitable for repairing the bottom of the roadway floor and side walls, as well as breaking large rocks and coal blocks.

The working arm has functions such as rotation, swing, and translation, which can achieve side excavation operations in tunnels.

Easy to operate, easy to learn and use, the operating lever and comfortable seat can alleviate driver fatigue.

Equipped with explosion-proof cable reels, it can flexibly and automatically retract cables, improving safety and automation.

The whole machine has a low price, significant functions, fast results, superior performance, and is suitable for repairing underground tunnels in coal mines.
