(14) 6x19 Classification Wire Ropes provide an excellent balance between fatigue and wear resistance. It is a very popular, general purpose rope that will give long service with moderately sized sheaves and drums, and is often used for hoists, boom hoists, haulage ropes and slings.
Galvanizing: For 6 x 19 Classification class A galvanized wire rope (EIPS & IPS grades only), deduct 10 % from the listed nominal strength
(19) 6 x 37 Classification Wire Ropes have a third layer of wires which make them more flexible, although less abrasion-resistant than ropes of the 6x19 class. Each strand contains numerous, comparatively small diameter wires which offer superior bending ability. As the number of wires in each strand increases, flexibility increases. Often used on winches and as hoist ropes on overhead and mobile cranes.
Galvanizing: For 6 x 37 classification class A galvanized wire rope (E1PS & IPS grades only) deduct 10% from the listed nominal strength.
(16) 19x7 Rotation- Resistant Wire Rope is a special class of rope designed to resist the tendency to spin or rotate under load. This is achieved by laying 6 strands around the core in one direction, then laying 12 strands around the first operation in another direction. It is often used for hoisting unguided loads with a single part rope. This unique design does, however, impose certain limitations on the rope's application and handling.
Note: These strengths apply only when a test is conducted with both ends fixed. When in use, the strength of these ropes will be reduced if one end is free to rotate.
(8) "7x19 Galvanized Aircraft Cable is a common industry term for small diameter, corrosion- resistant, zinc-coated wire rope originally designed for aeronautical applications. It is a flexible and inexpensive cable used on winches, guy lines and numerous other commercial, industrial and marine applications.
Also available with a flexible, vinyl P.V.C. coating that extends the cable's life by protecting wires from abrasion, dirt, grit and moisture, by sealing in lubrication and by reducing wear on sheaves and pulleys. Hands, clothes and other materials are protected from direct contact with wire."
