Introducing the CJY 20T electric locomotive, meticulously crafted for large-scale mining operations, available in underground and open-air variants. The underground model offers both single and double heading locomotive options. Each locomotive features advanced speed regulation using resistors, a V-shape rubber spring, and a robust combination of three braking systems: hand-wheel, resistor, and air braking. Notably, the double heading locomotive boasts synchronized control via a PLC programmable microcomputer, utilizing a secure three-core shielded cable. The open-air variant of the 20-ton locomotive showcases a fully enclosed construction with an elegant appearance, ensuring reliable performance and exceptional tractive power. This locomotive is designed for high-speed operation and superior functionality.
