Specialty Excavating

Controlled excavation with unmatched vacuum power

Loram’s LRV is a powerful, rail-mounted specialty excavating machine that removes up to 38 cubic meters of material per hour using mechanical agitation and airflow. The most productive vacuum-based maintenance of way excavation machine on the market, the LRV combines a diesel engine-powered manipulator arm and powerful, twin engine vacuum pumps, making it capable of excavating a host of material challenges including compacted or ice-crusted ballast, mud, water, sand and soil.

The versatile Loram LRV offers precision control with unmatched power, applying an industry-leading 2,268 kilograms of force to break up tough material in a way that a rotating nozzle alone cannot. Compact power and control makes it ideal for excavating specialty trackwork, trackside equipment and yard applications, with maximum accessibility to traverse and operate within restricted clearances, including tunnels, passenger platforms and bridges.

The LRV offers unmatched flexibility to accommodate hard to reach track structures. The nozzle can tilt 45° from vertical in any direction to reach ballast under hard to reach track structures, such as third rail. The nozzle can also work at distances up to 4.5 meters from track centerline, maximising the work area.
