JG80LT 8-ton Hirail excavator with ballast cutter
The JG80LT crawler ballast undercutter is a track-based dedicated excavator designed for railway ballast maintenance. It retains durable crawler traveling structure, fitted with auxiliary rail wheels to run on railway tracks, mainly used for excavating aged ballast below sleepers, cleaning sleeper cribs and removing polluted ballast. Its robust crawler chassis delivers excellent passing performance on gravel, uneven construction ground; auxiliary rail wheels enable convenient movement along rails. High-strength wear-resistant working arm adapts to long-time heavy digging of compacted ballast. This crawler undercutter lowers labor input, speeds up track bed renovation, runs reliably under complicated railway construction environments, serving as key equipment for railway maintenance contractors.
