MWY6.3/0.3 Heavy-Duty Electric Hydraulic Excavator for Coal Mines – 37kW High-Strength Arm with Load-Sensing System & FOPS Cab

1. What are the voltage specifications for the electric motor?
The excavator is equipped with a 37kW electric motor designed for dual-voltage operation, supporting both 660V and 1140V power supplies to adapt to different mine site standards.

2. Is the excavator suitable for heavy-duty underground operations?
Yes, it is specifically engineered for coal mines. The working arm and cylinders are reinforced with high-strength materials (690 MPa yield strength), ensuring reliable performance and durability under heavy loads.

3. What is the digging force and bucket capacity?
The machine delivers a maximum bucket digging force of ≥40 kN. It comes standard with a 0.3 m³ bucket, though a 0.2 m³ bucket is available as an option.

4. How does the machine ensure operator safety?
Safety is a priority. The excavator features a FOPS-compliant operator cab to protect against falling objects. Additionally, the travel and slewing mechanisms use an oil-cut brake system (spring-loaded friction discs) that automatically engages if hydraulic pressure is lost.

5. Can this excavator be used for tasks other than digging?
Yes, it is versatile. Aside from the standard bucket, it can be equipped with an optional hydraulic breaker (325 J impact energy) for breaking hard rock or coal.

6. What type of hydraulic system does it use?
It adopts an advanced load-sensing variable displacement system with integrated proportional pilot control. This system significantly improves efficiency, reduces heat generation, and ensures smooth movements.
