Maintaining the ballast layer directly beneath the sleepers is crucial for a robust track structure. Over time, ballast degrades and becomes fouled, compromising its ability to drain, bear loads, and withstand forces. Undercutting is essential to restore these properties. This process involves the continuous excavation of material below the sleepers, which can either be entirely wasted or screened, with only the fine particles discarded, and the clean ballast returned to the track.
Loram offers two automated undercutter solutions, delivering industry-leading productivity and re-establishing a more permeable, stronger ballast structure. The Loram UC1200 is an undercutter cleaner that reclaims larger, cleaned ballast. Conversely, the Loram Track Lifter Undercutter (TLU) is a waste-only undercutter. Both machines feature patented, state-of-the-art digging wheels that provide self-supporting cut-in capabilities. The UC1200 and TLU are operational in a fraction of the time compared to competitive machines, requiring no additional support equipment or excavators, which simplifies operations and reduces costs.
