Getman shotcrete sprayers are designed to quickly and efficiently perform all shotcrete operations required in underground mining, offering an unparalleled boom coverage area that enables extended spraying coverage in normal drifting situations.  Optimal boom positioning minimizes wasted material, and improves coverage when shooting blind corners and bulkheads.

Getman’s SST Shotcrete can maintain optimal horizontal positioning when spraying tunnels ranging from 3.5 m by 3.5 m (11.5 ft by 11.5 ft) up to 10.3 m wide by 6.2 m high (34 ft by 20 ft), while covering 4.3 m (14 ft) of advance from a single setup. An available onboard air compressor enables fully contained spraying using only the diesel engine, while the high-lumen LED lighting allows for optimal visibility of the spraying area.

SST shotcrete sprayers protect worker safety through the ergonomically designed operator’s compartment that reduces operator fatigue during tramming.  Work areas are fully illuminated ensuring proper visibility at all times.
