ABSTRACT:
A remotely controlled, hydraulically operated cutter apparatus for use in a conduit includes control panel for generating a plurality of control signals for controlling the operation and a source of pressurized hydraulic fluid. Valves are provided for receiving both the pressurized fluid and the control signals, and for distributing the received fluid in accordance with the received control signals. A hydraulically powered cutter motor located within the conduit and including a cutting tool receives hydraulic fluid from the valves for driving the cutting tool. The cutter motor is supported within the conduit by a structural unit. A first hydraulically actuated cylinder is included for receiving hydraulic fluid from the valves and for centering and holding the structural unit in a fixed axial position within the conduit. Second, third, fourth and fifth hydraulically actuated cylinders are provided for adjusting the axial and radial position of the cutter motor, for rotating the cutter motor and for adjusting the angular position of the cutter motor to facilitate cutting by the cutting tool.
