Abstract/Summary

The results of trials to investigate the forces required to tow cables and small sledges on Antarctic snow are discussed. Once moving, cables which were straight and towed at a constant speed showed drag factors of between 20 and 30%. For non-straight cables the drag factor could rise to 40% or more. A loaded sledge on a firm snow surface showed a drag factor of around 10%. The forces required to start the cables or sledges moving showed a much wider and less predictable range of drag factors.
