Developed to complete and improve the concrete spraying process
Putzmeister MIXKRET 4 is designed to complete the concrete spraying process in underground mining. The concrete mixing drum has a maximum concrete capacity of 4m³, and the 6-cylinder, 130kW (176 HP) engine provides great climbing and movement power.
KEY FEATURES
- Safety first: automatic speed regulation system enables full-load traveling at the maximum safe speed
- Great climbing and driving power: powerfull 6-cylinder, 130 kW (174 HP) engine
- Operation at high altitude: AAC (Automatic Altitude Compensation) system for stable engine performance
- Reduced fuel consumption and noise levels: Integrated Continuously Variable Drive (ICDV) ensures the correct relationship between engine torque and speed
