The Shearer MB - its parameters represent already a powerful mining machine designed for high-capacity wall working faces having thickness up to 5 meters. The shearer is designed for both-direction, stable-hole-free coal mining in areas classified as SNM 2 environment, with partings having strength up to 60 MPa, and the gradient in the direction of the working face front ±25 degrees, and the gradient perpendicularly to the working face front up to ±35 degrees.

This extracting machine is an electric two-cylinder shearer with two pulling electric winches controlled by a transistor frequency converter, with motors of cutting elements located in the arms, with a computer evaluating the machine operation, and with remote control. Swing arms can be completed with stroking shields improving the loading capacity.

Cutting elements of the shearer are fitted with a middle-pressure internal spraying in order to decrease the possibility that a methane-air mixture can be ignited by the knives of the cutting elements. The choice of both cutting tools and knife holders is up to the customer´s requirements.

Climatic workmanship of the shearer including accessories gives the guarantee of its trouble-free operation in the conditions of increased coal dust amounts, increased relative humidity and temperature, and in the presence of mine water with deleterious effects, too.

The advantages of the shearer are its short construction length, increased stiffness and variability - considering different combinations of driving units, cutting tools and accessories according to the customer´s needs.

Basic technical parameters:

Seam thickness: 1,8 - 5,0 m (according to the type)
Total output of motors: 481,5 - 712 kW (according to the type)
Performance (the coal strength max. 360 kN/m): 20 - 37 t/min (according to the type)
Face gradient longitudinal: ± 35°
Face gradient laterall: ± 20°

The Shearer MB 12 compact is designed for two-sided, stable-hole-free coal mining in working faces with partings having strength up to 60 MPa, and the gradient in the direction of the working face front ±25 degrees, and the gradient perpendicularly to the working face front up to ±35 degrees.

This extracting machine is fitted with a chain-free travel using stepless transistor automatic regulation of the rate of the face advance in dependence on the mined rock strength. The travel device having two winches and a magnetic brake ensures safe motion on the scraper conveyor with different types of horizontal elements, as for example EIKOTRACK, or HODOTRACK are.

The Shearer MB 12 compact meets explosion- and spark-proof safety requirements, and is allowed to be used in areas where the risk of methane- air mixture explosion occurs.

Climatic workmanship of the shearer including accessories gives the guarantee of its trouble-free operation in the conditions of increased coal dust amounts, increased relative humidity and temperature, and in the presence of mine water with deleterious effects, too.

The shearer can be operated locally from a panel which is located on the compact machine body, and by a remote radio set.

The advantages of the shearer are its short construction length, increased stiffness and simple installation, as all parts excluding arms are located in a compact monoblock body.

Basic technical parameters:

Seam thickness: 0,95 - 3,0 m (according to the type)
Total output of motors: 291,5 - 491,5 kW (according to the type)
Performance (the coal strength max. 360 kN/m): 8,7 - 17 t/min (according to the type)
Face gradient longitudinal: ± 35°
Face gradient laterall: ± 20°

Shearer MB444P is designed for low seem thickness starting from 0,7 to 3,0 m. The facility keeps the high performance, typical for the MB serie shearers. Itœ designed for the biderectional mining with partings and face longitudinal gradient(along the pillar) ±35 degrees, laterall gradient ±20 degrees.

This electrical cutting loading shearer is equipped by two haulage winches driven by frequency convertor, remove controller and PC diagnostics.

The cutting drums is supplied with medium pressure spraying eliminating the air methan danger of combustion. Shearers can be operated in SNM2 condition. The cutting knives and drums can be delivered according to customers requirements. The climatic resistance of the shearers including itœ accessories ensures the smooth run of the shearer in the coal dust accurance area, area of increased relative humidity or temperature and in the areas of the aggressive water in mines.

Basic technical parameters:

Seam thickness: 0,7 - 1,5 m
Total output of motors: 444 kW
Performance (the coal strength max. 360 kN/m): 6 - 7 t/min
Face gradient longitudinal: ± 35°
Face gradient laterall: ± 20°

Shearer MB 1500 ESG is designed for biderectional mining with partings  having strength u to 60 Mpa,  atd the gradient in the direction of the working face front +/- 25 degrees, and the gradient perpendicularly to the working face frong up to +/- 35 degrees. The shearer is equipped with chainless travel unit which enables automatical speed regulation by frequency inventer according to hardness of the coal. In the shearer are placed two traversing mechanisms with hydraulic brakes for safe movement of shearer on the scraper face conveyer of thy type JUMBOTRACK. There are motors for running of the drums in the arms of the shearer.

Shearer is instrinsically safe. He can be used in the environment with the explosion danger.  Sanitary and hygienic performence of the shearer enables troubl-free working in the environment with the high content of coal dust, higher humidity and temperature and alsoin the environment with presence of aggressive mine water.  Shearer is controlled from the panel which is placed on the body of the shearer or can be remote-controlled by wireless control system. Central part of the shearer consists of three parts, which are hydraulically connected.

Basic technical parameters:

Seam thickness: 2,0 - 5,5 m
Total output of motors: 1214 - 1584 kW
Performance (the coal strength max. 360 kN/m): 20 - 60 t/min
Face gradient longitudinal: ± 35°
Face gradient laterall: ± 20°
