Basic rules by which a contractor could overcome the critical operating problem are listed, and the methods by which a contractor can determine the critical load time by analyzing the loadability of a given scraper-pusher combination in a specific material are outlined. The development of a load growth curve is detailed, and the computation of the optimum scraper load time, and pusher production is described. Maximizing fleet production is discussed as well as optimum load time and cost/BCY. Operating at optimum load time in the cut will given maximum production at a minimum cost/yd. It is, however, important to insure that knowledge of the optimum load time be used by operators. Either the cut foreman or the pusher operator can be instructed to keep time and to signal the scraper operator when the optimum load time is attained.
