The SPM 500 Wetkret has proven it's efficiency and reliability in a large number of tunneling projects all over the world.
With a vertical spraying reach of 17 m and an output of 30 m³/h, this machine 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, assure 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.
