Self-propelled ballast cleaning machine for on- and off-track work |
摘要 |
A self-propelled ballast cleaning machine useful for work in track switch and other widening track sections comprises selectively operable on- and off-track undercarriages supporting the machine frame for selected on- or off-track operation. A ballast excavation chain adjustable in width for operation in widening track sections delivers excavated ballast to a screen for cleaning the ballast and the excavated ballast is stored immediately adjacent a ballast excavating chain portion when it may be discharged in controlled amounts. A vertically movable plow levels the discharged ballast and includes plowshares adjustable for leveling ballast in widening track sections.
