The mechanized concrete spraying system Wetkret 3 is designed for shotcreting in small tunnel sections with difficult access. Mounted on a compact crawler chassis with a 17,9 kW Diesel engine, the equipment features hydraulically operated support legs and an optional +/-30 º tilting system, guaranteeing stable operation in ascending and descending slopes.
The telescopic spraying arm with a maximum reach of 8,79 m permits working in minimum sections of 2,5 m and is operated by remote control (dual use by cable and wireless).
Wetkret 3 can be easily and quickly connected to a concrete pump, air and additive supply, in a way that prevents the use of external hoses interfering with the work.
