Introduction:
Powered by Cummins explosion-proof diesel engine, MWC series hydraulic mining excavator is suitable for excavations operations of rock loading, bottom cleaning and permafrost excavation in coal mine shafts, inclined shafts and level road. With the best load-sensing hydraulic system, the bucket, forearms and booms can coordinate flexibly, quickly and efficiently under any circumstances, and the powerful digging force can play excellent work efficiency and excellent performance in a short time. Modular design, compact structure, simple appearance, convenient operation, flexible maneuvering, good stability, easy for disassembly and assembly, the machine is convenient for vertical downhole uses .
Features :
1 The explosion-proof diesel driven excavator for coal mines is one product designed for repairing roadways, leveling roadways, digging ditches, crushing, loading and other tasks, complying with related terms"Coal Mine Safety Regulations" 2016 edition and "Coal Mine Safety Quality Standardization Standards"2017, and coal mine safety certificates (including whole unit and individual equipment and accessories), explosion-proof certificate, and product certificate in accordance with national coal safety requirements are also be provided .
2
With the Cummins explosion-proof diesel engine for power, the fourth generation TDCI, it meets the national III emission standard, owns the coal safety certificate and the national III emission report issued by national testing center; low fuel consumption, high torque, strong power and climbing ability; matched with the replaceable high-power hydraulic breaker, is especially effective in selective mining and non-blasting mining operations, performing unique advantages.
3
The material and performance of installed parts are especially suitable for use in harsh underground conditions. All cylinders use Yelong" brand engineering hydrauliccylinders and imported seals, which have good sealing, high reliability and long service life
4
The working device is a three-section boom, which can operate flexibly in sections of different heights to meet the requirements of full-section excavation without dead ends, and the three-section boom oil cylinder adopts a built-in structure to avoid collision during the work process to increase the safety of operation.
5
The operation is safe and convenient, no suffix cable dragging, which can realize workplaces rapid transferring and achieve long-distance operation requirements in the roadway;
6
The turntable part can realize 360°rotation, while the auxiliary arm can realize ±90° rotation, and the working arm can realize 360° barrier-free crushing and excavation at different heights in the roadway.
7 The turntable part can realize 360°rotation, while the auxiliary arm can realize ±90° rotation, and the working arm can realize 360° barrier-free crushing and excavation at different heights in the roadway.
8
Equipped with a protective cover for the working arm cylinder, and a steel wire sheath with the hose to avoid bumping and
damaging the cylinder and hose
9 Adopting the gas start mode, convenient and fast;also the exhaust gas treatment system (water washing treatment) can effectively absorb the engine exhaust gas, convert it into non-toxic gas and discharge it, effectively purifying the working environment
10 The working device can be matched with quick joints (also known as quick hitches), which can be fast installed and switched to attachments of various configurations (such as buckets, rippers, breakers, hydraulic shears, etc.) to expand application , time
saving and high efficiency.
Environmental Conditions :
1 The slope of the roadway should not exceed the degree specified in the standard;
2 The ambient temperature of the roadway is -5ºC~+40ºC, and the maximum relative humidity is not more than 90% (when the temperature is 25ºC);
3 The altitude of the place of use does not exceed 1000m. When used in a plateau environment with an altitude of more than 1000m, necessary measures shall be taken for special design according to the situation.
4 The Proctor hardness f of the rock is less than or equal to 10, and the loose density is not more than 1.8t/m³.
5 The voltage limit deviation is ±5%, and the AC frequency limit deviation is ±1%.
6 The water height of the working area is lower than the rail surface.
7 The coal dust and methane explosive gas around the excavator shall not exceed the safety content specified in the "Coal Mine Safety Regulations".
