The Mechanical Handling and Storing of Material

28o THE MECHANICAL HANDLING OF MATERIAL I he greatest length worked in one continuous section on the system in question is the lower half of a ropeway built for La Compania EsplotoÜora de Salinas, in Chili, which is 8,500 m. long between stations, or in other words, requires an endless rope of l/,000 m. rhe heaviest line is that installed for the Compania Minera Minas del Riff, at Melilla, which nominally carries 150 tons per hour, but which has been actually run with a capacity of 170 tons per hour (see Fig. 405). A series of lines having a total length of 23 km., built in 1903 for the Bacares Iron Ore Co., give a good example of the exceedingly low rope wear on this system. On two of the ropeways, the ropes in each case have transported over a million tons of ore. Among other instances of long lives of ropes is a line built for the Cork-Bandon South Coast Railway, the same rope has now been running for twelve and a half years and on an installation constructed for Messrs Newell at Dalbeattie, the original rope has been working for twelve years. At the present time both these ropes are in good condition.
