Description

SPM 4210 Wetkret

The SPM 4210 WETKRET series is ideal for small and medium section tunnels and galleries. Its spraying arm provides 10 m spraying reach. The dual cable and wireless proportional remote control permits easy handling of the arm movements, besides regulation of the concrete flow of 20 m3/h and adjustment of the additive dosage.

The standard version of the SPM 4210 WETKRET series is operated electrically and is optionally available with an electric or diesel air compressor built into the chassis

 

The Putzmeister concrete pump mounted on the equipment guarantees high performance, low pulsations and a long life for the wear parts. The proportional remote control permits full regulation of the concrete output as well as adjustments to the predefined additive dosage, to cope with the changing working conditions in underground mines. The synchronized additive pump is equipped with an automatic dosing device proportional to the concrete flow, thereby assuring spraying accuracy and quality. The heavy-duty chassis with state-of-the-art axles and a reinforced turning system provide great maneuverability.
