Mintrix Excavator
1 / 5
The EBZ260 roadheader utilizes a flame-proof and intrinsically safe switch box and control box. Characterized by its small size, light weight, and flexible operation, it ensures high safety and reliability. The main controller is housed in a closed casing to effectively block electromagnetic interference. Operational status is displayed via an LCD screen with a user-friendly menu interface. It includes comprehensive protection functions for overvoltage, motor overload, open-phase, short circuit, over-temperature, and earth leakage lockout.
The hydraulic system adopts a transfer case and multi-pump control architecture. Key hydraulic components are sourced from reputable international brands to ensure consistent performance and durability during underground excavation.
Equipped with both internal and external spraying systems. The front after-pick spraying strengthens dust suppression, while the overall design incorporates leakage detection to maintain operational efficiency and safety.
