Abstract
An ice removal auger is lowered by a winch into a generally cylindrical ice containment structure from an open upper end of the structure and is controlled remotely from the exterior of the structure, for cutting and removing a body of ice therewithin. The auger comprises a power drive assembly mounted on a carriage for relative translational and nonrotational movement with respect thereto, the carriage including selectively operable engagement means which are remotely controlled from the exterior of the ice containment structure for engaging the interior cylindrical wall surface thereof to stabilize the power drive assembly against rotation relative to the ice containment structure, the power drive assembly including a motor connected through a shaft to a cutter at the lower end of the shaft which drives same in rotation, while the assembly moves axially downwardly in translation relative to the carriage for gradual and continuous cutting and removing of the body of ice.
