ZRS-50 handheld emulsion drilling, hydraulic rock drill 
 Hydraulic coal drilling are widely applicable to the coal seam and soft rock under various conditions, to solve the coal drill easily sparks, operation and maintenance responsibility, and can stope beam nest, digging legs nest, coal mining face ideal for drilling work, the main features of the rig is: 1 The rig itself without power, with a safe, efficient features, especially for high gas and coal dust explosion hazard mining use; two drilling speed, the average faster than coal drill more than 1/3 of the time; three torque than coal drill can improve ergonomics twice; emulsion as a power source; compared to 5 and coal drill do not need to install power lines, electrical equipment and anti- Road dust and water pipes; 6 small size, light weight, simple structure, easy operation and maintenance can greatly reduce the labor intensity of the work. 

 Scope of application: 
 ZRS-50 handheld emulsion drilling rig is mainly used for machine mining face to play ahead of the hole, Face Caving hole, Fire Prevention and hole, ground water holes, explore the gas hole, the pressure taps is this kind of work most advanced handheld rig, you can replace the traditional coal drill and rock drill. Emulsion hydraulic pump to the coalface support for the power source is particularly convenient to use in the operations side of the mechanized mining. 
 Product Features: 
 East Asia handheld emulsion drilling installation is simple and convenient, without electricity and electrical protection devices, reducing the complexity of face equipment, eliminating the security risks. Stepless adjustment of the drilling speed and drilling materials of different hardness to do. Torque has a large, light weight, fast drilling, the use of safe and convenient operation.
