(7) Compact 19 is recommended for both multipart load and single part fast line applications. The compact strands help make this rope resistant to drum crushing.
(24) This classification of wire rope has the greatest range of application. It covers all six strand wire ropes containing as few as 19 wires per strand but not greater than 26 wires per strand. There are many different arrangements for these wires in the strand. The constructions in this classification with the greater number of wires are usually more flexible while the ones containing fewer wires are more resistant to abrasion and pressure.
(20) This classification of wire rope covers ropes containing six strands with the number of wires per strand varying from a minimum of 27 to a maximum of 49. These ropes offer greater flexibility because of the greater number of wires in their construction. This classification is normally found in ropes of larger diameters or in situations where small sheave or drum diameters exist.
(15) 8x19 Classification rotation resistant ropes are recommended for hoisting unguided loads with a single-part or multipart line. 19x7 is recommended for hoisting unguided loads with a single-part line only.
(28) The 6 x 19 Classification is the most widely used. With a good combination of flexibility and wear resistance, this class can used in a wide range of machinery and equipment.
(34) Wire ropes of this class are more flexible than 6x19 class ropes due to the greater numbers of wires per strand, however the resistance to abrasion is less than 6x19 class ropes.
