Mounted on a robust rubber-tracked crawler chassis, it delivers excellent stability with hydraulically operated support legs and an optional tilting system for ascending or descending slopes. Powered by a reliable 24 hp diesel engine, Wetkret 3 features a telescopic spraying arm with a 7 m horizontal reach, operated via both cable and wireless remote control for optimal flexibility. Its smart design includes dual-side concrete pipe connections and integrated air and additive supply lines to avoid external hose clutter. Built for precision and durability, Wetkret 3 is the ideal shotcreting solution for challenging terrains and hard-to-reach underground applications.
