. Material handling cyclopedia; a reference book covering definitions, descriptions, illustrations and methods of use of material handling machines employed in industry . Locked-Coil Track Cable of sufficiently small diameter to allow the cableway car-riers to pass over them. Flat Rope Flat rope is used chiefly for hoisting purposes, beingespecially desirable when a large and long rope is re-quired for hoisting heavy loads out of deep shafts, as itdoes not spin or twist. It is also used for operating spoutson coal or ore docks and other similar purposes. It ismade up of a number of round wire ropes of alternateright and left lay, placed side by side and then sewed to-gether with soft iron or steel wire thus forming a com-plete flat rope. The sewing wires are much softer thanthe steel wires composing the strands of the round ropes,and act as a cushion for the strands. This causes themto wear out much faster than the harder wires composing 16 Ropes—4 7-Wire Strands, 1 Hemp Core per Rope. Flat Hoisting Rope the rope and therefore the flat rope must sometimes beresewed with new wire. Should any of the rope strandsbecome badly worn or damaged, they may be replaced bynew strands and the complete flat rope continued in service. Flat rope winds on itself and requires a reel but littlewider than the width of the rope. This feature is of par-ticular advantage where space is limited and the wide,heavy drum that would be required for a large and longround rope could not be installed or would not be desirablefor other reasons. Flat rope is made from 2 in. to 7 in. inwidth; from Y^ in. to ^ in. in thickness; and in lengthsvarying from 20 ft. to 3,000 ft. The approximate capacities of wire rope, made of ironand steel of various grades, are given in the tables shownon the following pages. 324 HOISTING MACHINERY Ha gv 1=1 a -c gc,oO. 2 c on. |es-5 l;.3°g III!
