Description
As one of the earliest designed and developed excavators in our company, JG80L tracked excavator provides comprehensive and mature techniques. Undercutting is frequently performed as an independent service for cleaning stretches of track. It is also deployed as part of larger maintenance of way and environmental projects.
This mini crawler excavator specifically designed for use off-track cutting ballast, is a revolutionary system designed to undercut track without wasting valuable track time, scooping out contaminated gravel and mud and fouled ballast from beneath railroad tracks.
