DRILLING RIG WITH HINGED, RETRACTABLE OUTRIGGERS

摘要

A mobile drill rig includes a frame structure and a plurality of hinged outriggers that are adapted to be retractable to a substantially vertical position during a drilling operation and extendable to a substantially horizontal position during movement of the mobile drill rig. The frame structure is adapted to transfer a weight of the mobile drill rig through the plurality of hinged outriggers to a plurality of wheeled frame dollies during the rig movement. A method includes coupling a plurality of outriggers to a drill rig structure, supporting the weight of the drill rig structure with the plurality of outriggers, and moving the drill rig structure while supporting the weight with the plurality of outriggers.
