The Lombrico remote controlled, double-tracked crawler gets the vacuum hose-end directly into dangerous and hazardous material and hard to reach places - keeping the Operator out of harm's way. Ideal for confined spaces and no man entry in such environments as steel plants, refineries and mining operations, the innovative Lombrico mini excavator can be used to vacuum settled material in sewage pipelines, manifolds and tunnels larger than 2.6 feet (80 cm) in diameter.
