Ideal for small and medium tunnels and galleries
SPM 4210 WETKRET boasts a vertical spraying reach of 10m and a maximum concrete flow of 20m³/h. Its synchronized additive pump is equipped with an automatic dosing device proportional to the concrete flow, thereby assuring spraying accuracy and quality. The dual cable and wireless proportional remote control permits easy handling of arm movements, besides regulation of the concrete flow and adjustment of the additive dosage. With state-of-the-art axles and a reinforced turning system, the chassis is ideal for the rough working conditions in underground mining. The SPM 4210 WETKRET series comes as electric or DUAL DRIVE (spraying operation electric or Diesel) version and is optionally available with an electric or Diesel air compressor built into the chassis.
