Longwall Continuous Miner Coal-Winning Machine

Longwall Continuous Miner Coal-Winning Machine

Our continuous miner is known worldwide for our ability to provide the highest performing, most reliable cutter head gear cases in the industry. It includes a solid-head cutting head system, with a variety of cutter bit lacing configurations available.
Our hydraulic manifolds, standard on all continuous miner models, reduce hose assemblies and fitting counts to significantly reduce hydraulic fluid leak points. 
All serviceable parts for a circuit are in one common location and all pressure check points allow gauge connection/disconnection. Screw-adjusted relief valves are standard, while bolt-on caps permit easy access for troubleshooting/replacement on hydraulic or water segments.
Mucking loader with cutting head is one type of high efficiency, multifunctional,environment protection machine integrating moving,digging,collecting,loading,conveying and dumping. Mucking loader with cutting head is widely used for coal cutting in the narrow and restricted tunnel of coal mine,no blasting is required.

Product Features：

Strong cutting ability
The core technology of pick arrangement realizes the optimal design of pick arrangement under different working conditions, improves cutting efficiency, reduces pick consumption, and realizes large cutting depth and high efficiency cutting.

Wide range of applications
The cutting range covers 1.8-4.5/2.4-5.1 meters, which can be applied to more than 70% of coal mine roadways. With strong climbing ability, it can be applied to coal mine roadways with a slope of ±17°. 

High reliability
The whole machine adopts the design concept of high safety factor, and the service life of key parts such as reducer can reach more than 10,000 hours. 

Cutting system protection technology
There is a patented "Adjustable Heart Torque Limiting Device" protection device between the cutting and the reducer, which effectively protects the machine from the impact and vibration of the cutting overload and reduces the working noise.

Strong loading and transportation ability
Create a precedent in the industry and adopt innovative design of shovel, transport and separate drive. The power is large, the efficiency is high, the material can be transported out quickly, the maintenance is easy, and the service life of the driving parts of the scraper is improved.

High dispatch efficiency
The walking frequency conversion drive realizes stepless speed regulation, and automatically adjusts according to the actual working conditions, so as to achieve the purpose of powerful work cutting and fast transportation speed.
