Machine item: KS80 shotcrete spraying machine + KP25 concrete pump
Application: railway tunnel, road tunnel, subway, mining roadway, side slope, water conservancy and hydropower tunnel
a) Hydraulic unfold working boom system includes six free working position, rotary of big arm, up and down of big arm, three unfolding small arm, rotary for spraying nozzle, swaying of nozzle, spraying nozzle brushing. That makes shotcrete machine more suitable for multi-layer excavation in tunnel condition.
b) Diesel drive system provides force to machine’s traveling or arm’s activity. Electrohydraulic power group provides power for spraying work.
c) Crawler chassis, equipped with two unfolding hydraulic outrigger leg to maintain the level of machine when it climbs slope.
d) Wireless remote control for unfolding arms working.
e) Mechanic arm dimension(traveling condition) L*W*H 3.2*1.6*2.5 m, 3 meters for minimum working radius in tunnel.
f) Spraying range(Includes one meter spraying distance), approximately 8.5 meters for max height, 14 meters for max width working site.
