1. What is the machine's spraying/output capacity?
The machine has an output capacity of 20 m3/h for wet shotcrete applications.
2. What power supply and motor power does it require?
Rated power is 66 kW and the machine operates on a 380 V electrical supply. Ensure site power matches these requirements.
3. What is the maximum aggregate size the machine can handle?
Maximum aggregate size is 20 mm. Use mixes formulated for wet spraying and within this aggregate limit.
4. What are the concrete pumping pressure and air consumption?
Concrete pumping pressure is rated at 8 MPa. Compressed air consumption is 10 m3/min (for pneumatic components/nozzle assist as specified).
5. What is the hose specification?
The standard hose inner diameter is 160 mm. Use recommended shotcrete hoses and inspect them regularly for wear; consult the manufacturer for approved hose types and maximum recommended hose lengths for your application.
6. What are the machine dimensions and weight?
Overall dimensions are 8000 × 2000 × 2450 mm (L × W × H) and the machine weight is 16,000 kg.
7. What does 'Max. Conveying Distance 8*13m' and turning radius mean?
The specification lists '8*13m' in conjunction with the machine's compact turning capability—this corresponds to a minimum turning radius of approximately 8 m (inside) and 13 m (outside). For long concrete conveying runs, consult the supplier for recommended hose layout and achievable conveying distance under your site conditions.
8. How is the machine moved and controlled on site?
It features hydraulic four-wheel drive and supports multiple walking styles (four-wheel steering, diagonal steering, and in-situ turning). Operation is via a wireless remote control for convenient maneuvering and jobsite positioning.
9. What chassis and axle components are used?
The axle chassis system uses durable components from Dana / Carraro (Italy), designed for heavy-duty, stable movement on construction sites.
10. What typical applications is this machine best suited for?
Ideal for concrete spraying on construction sites, tunnels and underground works, renovation and repair projects, and large-scale shotcrete applications requiring fast, durable surface creation.
11. What training and operator requirements are recommended?
Operators should be trained in shotcrete wet-spray techniques, safe machine operation, and maintenance procedures. Manufacturer or authorized dealer training is strongly recommended before first use.
12. What routine maintenance is required?
Daily inspections and cleaning of hopper, pump, and hoses; check hydraulic fluid and filters; grease lubrication points; inspect electrical connections and remote control; replace worn hose segments and nozzles as needed. Follow the manufacturer's maintenance schedule for intervals and parts.
13. What safety precautions should be followed when using the machine?
Use appropriate PPE (eye/face protection, respirators where required, gloves, hearing protection), secure and ground electrical supply, follow lockout/tagout procedures before maintenance, ensure adequate ventilation in confined spaces, and maintain safe distances from moving components and hose lines under pressure.
14. How is the machine transported and installed on site?
At 16 tonnes and wheeled chassis, transport requires suitable heavy-load vehicles or trailers and appropriate lifting/ramps for loading. On arrival, position with the hydraulic drive and steering systems; final commissioning should be carried out by trained personnel or dealer technicians.
15. Are spare parts, service and warranty available?
Spare parts, technical support, and warranty terms vary by supplier and region. Contact the manufacturer or your authorized dealer to confirm spare parts availability, service packages, and warranty coverage for this model.
