Specialty Excavating

Ballast Maintenance

Speciality Excavating

Throughout every railroad, there are specialty trackwork areas that are too restrictive for mechanized machines to perform the simplest of tasks such as ballast excavation. Maintaining areas such as tunnels, bridges, switches and passenger platforms are among the most expensive part of any railroad maintenance budget, yet commonly the most neglected as they create unique and difficult challenges. Traditional methods of repairing specialty trackworks require significant resources and track outages. As a result, maintenance is often delayed in these areas, resulting in a variety of debilitating ballast and subgrade problems.

Loram specialty excavators are a specialized vacuum excavator with unique flexibility that lead to non-invasive maintenance techniques allowing railroads to properly maintain specialty trackworks. The specialty excavator provides precise nozzle control for targeted material removal without damage to track components, which accelerates the remediation of the track structure. Remediating specialty locations leads to increases in the load bearing capacity, restores drainage in these areas and increases the overall maintenance completion rate in these difficult areas. These self-propelled, track-mounted machines optimize railroads maintenance activities and avoid service interruptions
