Abstract : A review of operational requirements indicates a continuing need for equipment to excavate ice to facilitate polar construction. A 30-hp ladder-type trencher was selected and purchased for its low ground pressure and versatility. The chain was outfitted with specially designed conical ice teeth, and a rotating ice chipper drum was designed and fabricated for the backhoe arm. Both modifications were tested in a laboratory situation for performance and suitability for field operation. A similar, but larger machine with identical teeth, procured under a separate task, was observed during and extended Antarctic ice-trenching operation. Laboratory tests and field observations showed that the ice excavation machine was easy to operate and provided maintenance-free performance during all of its trials.
