2013 best selling handheld hydraulic coal drilling ZRS-50/420 buy wind coal mining machine drill manufacturers Huixin 0537-22802801 Q: What is a handheld hydraulic coal drilling? ? Mainly used in what areas? ? ? A: hydraulic coal drilling is widely used in a variety of conditions seams and soft rock, to solve the coal drill volatile explosive, responsible for operation and maintenance and other issues, and as a stope beam nest, digging hamstring purposes is mine ideal stope drilling work. 2 Q: ZRS-50/420 handheld hydraulic coal drilling What are the advantages? ? ? A: The rig's main features are: 1 The rig itself is without power, with a safe, efficient characteristics, especially suitable for high gas and coal dust explosion hazard mine use; 2 drilling faster on average than coal drill faster than 1/3 of the time; 3 large torque, more than twice as much coal drill can improve work efficiency; 4 to the emulsion as a power source; 5 compared with the coal drill need to install power lines, electrical equipment and dust-water pipeline ; 6 small size, light weight, simple structure, easy operation and maintenance, can greatly reduce the labor intensity of the work. Handheld emulsion drilling installation is simple and convenient, without electricity and electrical integrated protection device, reducing the complexity of the face of the device, eliminating the security risks. And hardness for different substances do stepless adjustment hole drilling speed. With torque, light weight, fast drilling speed, safe, and convenient operation.
