Underground Trolley Mine Narrow Gauge Tunnel Stringing Electric Locomotive
Product Overview
The Electric Trolley Underground Mining Locomotive uses a DC electrical line that is transformed into three-phase AC via a computer-controlled traction transformer, enabling variable voltage and frequency adjustments. This technology drives two AC asynchronous motors that operate the locomotive through a reduction gear driving axle. With core parts such as the traction transformer featuring 32 digital DSP chips, this locomotive delivers high speed and quick response, making it efficient and reliable for a range of industrial applications.
Ideal for narrow rail transportation in fields like coal mining, metallurgical industries, forest operations, and tunnel construction, this electric trolley locomotive is designed for use at elevations of up to 2000m in metal mines or non-hazardous areas. It offers excellent performance and low maintenance, avoiding issues such as ring fires or motor burnout typically seen in DC-driven locomotives.
Key Features
- Advanced Motor Technology: Reliable AC electrical motors provide a wide range of speed regulation.
- Efficient Performance: Quick response and high traction capacity make it ideal for industrial tasks.
- Low Maintenance Costs: AC motors reduce operational wear, leading to less frequent maintenance needs.
- Wide Application: Perfect for use in coal, metallurgical, mining, forest, and tunnel construction.
- Variable Speed Control: AC frequency change allows for smooth operation and precise speed control.
