How two Australian men rewrote the rules of ripping

(1986) How two Australian men rewrote the rules of ripping. The Earthmover and Civil Contractor, April 1986. pp. 22-23 [Publication] [Special Collections]

Summary

Two Sydney men have developed a completely new method of ripping with large dozers in very hard rock, which has resulted in a drastic decrease in the use of ripper boots and improved fuel consumption. The new method has been developed over the past five years by Ted Jones, a former manager of purchasing and stores with Thiess Bros and Dave White, metropolitan mechanical supervisor with Thiess. The method was devised out of the company's experiences at Menai in the southern suburbs of Sydney, where the Sydney Metropolitan Waste Disposal Authority set up the largest landfill site in Australia.

This article contains two images: a portrait of Ted Jones; and a Thiess D10 with the ripper in position. Also two diagrams: how to recut the ripper line to achieve the correct position for peeling; and two fanlike pressure waves exerted downwards by the D10.
