Product Description

Product Description

Product Overview of Shotcrete Machine for Underground Mining - AWT20

AWT20 shotcrete spraying machine is special designed for the spraying support operation of underground mining, water diversion tunnels, inclined shafts, etc. The maximum spraying volume can reach 20m³/h.

Main Features
1. With robust and compact chassis, reduced turning radiuses and crab-mode that allow a major range of movements.
2. Applying homogeneous shotcrete technique, ensures the required quality and layer thickness of concrete, as well as reducing rebound. 
3. The maximum vertical reach of the spraying arm is 8 meters.                                                                                                                        
4. Automatic additive dosage: equipped with an automatic dosing device proportional to the concrete flow, ensuring spraying accuracy and quality.      
5. Easy to operate: thanks to the wireless proportional remote control, the spraying arm can achieve smooth movement.
6.Easy maintenance and repair.
7.On-board electric air compressor.
