Abstract

A device and system for removing structures embedded in surrounding material is disclosed. Embodiments include a powered, expandable clamp attached to a rotating cutting tool for removing manholes from roadways. Select embodiments include anchoring a clamp to a manhole and using the manhole itself as leverage to move a cutting device through the surrounding material. Alternate embodiments allow an operator, working alone from a control station, to secure the manhole remover to the manhole, cut through the surrounding roadway, remove the manhole, and deposit the manhole at another location without requiring the operator to leave the control station. Further embodiments optionally include a depth gauge indicating the penetration depth of the cutting tool, an indicator reflecting the expanded state of the clamp, a pendulum mount allowing the clamp and drum to vertically orient using gravity, and/or the ability to attach to a host machine, such as a skid-steer loader.
