The CJY 20T electric locomotive, a remarkable engineering feat, is meticulously tailored for expansive mining operations, available in two innovative types: underground and open-air. The underground variant further diversifies into single and double heading configurations. Each locomotive is equipped with advanced speed regulation technology facilitated by resistors and V-shape rubber springs, complemented by a trio of robust braking systems: hand-wheel, resistor, and air brakes. In the sophisticated double heading unit, synchronized control is flawlessly achieved through state-of-the-art PLC programmable microcomputers, linked by a three-core shielded cable. The open-air type, with its fully enclosed design, boasts not only a striking aesthetic but also unparalleled performance, delivering formidable tractive power and exceptional speed. Its robust construction ensures reliability and efficiency, making it a preferred choice for demanding mining logistics.
