SPM 500 Wetkret
Proven Efficiency and Reliability in a large Number of Tunneling Projects all over the World
With a vertical spraying reach of 55' 9" (17 m) and an output of
39 yd³/h (30 m³/h), the SPM 500 WETKRET is ideal for medium and large
tunnels, caverns and slopes. The automatic system for high precision
synchronization between the concrete pump and the additive dosing unit
maintains the additive dosage proportional to the output, assuring
spraying accuracy and quality. All functions are available via remote
control. The sturdy chassis with 4-wheel-drive and crab-mode provides
maneuverability in difficult driving situations.
The standard version of the SPM 500 WETKRET series is operated
electrically and includes an electric air compressor built into the
chassis. The equipment is also optionally available with a diesel
drive system, allowing operation in places without electrical power supply
