Description

WETKRET 3

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 +/-30º 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)
