Designed to work easily and safely on jobs with difficult access
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 17,9kW 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 9m permits working in minimum sections of 2,5m and is operated by remote control (dual use by cable and wireless). Wetkret 3 can be easily and quickly connected to the concrete pump, air and additive supply, in a way that prevents the use of external hoses interfering with the work.
KEY FEATURES
- Designed to work easily and safely in areas with difficult access
- Stable transport and operation in any terrain: rubber-tracked crawler carrier with hydraulically operated support legsfor use on uneven ground
- Sturdy and ergonomic design of spraying arm: with long vertical reach of 9 m (29’6”)
- Proportional remote control for safe transport and operation: dual use by cable or wireless by Bluetooth
- Easy connection with the concrete pump, air and additive lines: connections for concrete pipes on both sides, no disturbing hoses for air and additive supply on the sides
- Dual operation: Electric or Diesel
SPECIAL FEATURES
Tilting system and other optional components for steep slopes: maintaining the machine in horizontal position in gradients of up to +/- 30º to assure correct spraying angle and stable arm reach
