. Material handling cyclopedia; a reference book covering definitions, descriptions, illustrations and methods of use of material handling machines employed in industry . Round-Wire Track Cable used in the construction of rope designed for haulage orhoisting service. This form of construction is not veryflexible, but, as it brings a larger number of the wires tothe surface of the rope, it provides a greater wearing sur-face, thus prolonging the life of both the rope and the cablecarrier wheels. Track cables are made with round wirethroughout, or with inner layers of round wires, and outerlayers of wires formed with an interlocking section calledlocked-wire or locked-coil. The most common type of track cable consists of 6 roundwires laid around a round wire center and then coveredwith other round wires in successive layers of 12 and 18wires. These wires are then twisted together to form thecable which is substantially one large strand composed of37 wires. Locked Cable Locked-coil and locked-wire rope or cable are similar inconstruction except that the locked-wire cable is composed. Locked-Wire Track Cable of a greater number of wires than is used inthe locked-coil cable and it therefore is more outside layers are formed of interlocking sectionswhich give a very smooth bearing surface. This typeof construction also minimizes vibration under stress and reduces the tendency of the individual wires to crystallizeand break. There being no interstices between the wires, agreater amount of metal is used in a given diameter andthus a maximum strength is obtained. Due to its compactconstruction, the locked design offers great resistance tothe crushing tendency of the loads passing over it. This type of rope cannot be spliced like ordinary wirerope and any joints required must be made with couplings
