STORING STEEL WIRE ROPES Ensure steel wire rope is stored in a weather-proof storage space. If wire rope is to be kept unused for a considerable amount of time, it must be protected from the elements. The ideal storage area is a dry, well-ventilated building or shed. Avoid closed, unheated, tightly sealed buildings or enclosures because condensation will form when warm, moist outside (ambient) air envelopes the colder rope. Although wire rope is protected by a lubricant, this is not totally effective since condensation can still occur within the small sections between strands and wires, thereby causing corrosion problems. Ensure the reels are kept up off the ground, or are placed on a concrete floor. Although the steel wire rope is lubricated at the time of manufacture, a suitable lubricant should be applied every three months. The reels containing the steel wire ropes should also be rotated 90 degrees every three months.
CORRECT HANDLING OF STEEL WIRE ROPES
Incorrect handling of steel wire ropes can cause kinking or loops forming in the steel wire rope, causing permanent damage. Below is a summary of the correct way to handle steel wire rope: • Reels should be mounted on jacks or placed on a swift (with a brake arrangement) and care taken to see that the reel rotates as the rope unwinds • Ensure clearance for free rotation of the reel when the rope end is pulled and maintain continuous tension during haul off • Over-winding should be avoided at all times to eliminate kinking • Always prevent crossing the rope laps on the wheel. Ropes should be stored in a clean dry place under cover. Reels or coils should be kept off the ground and support timber. They should also be examined periodically and rope dressing renewed as required. 1) Unreeling and Uncoiling Reels should be mounted on jacks and care taken to see that the reel rotates as the rope unwinds. Timber should applied as a lever to one of the flanges to act as a brake, keeping the rope tight and preventing the reel from ove running. When the ropes are supplied in coils a turntalbe or swift should be employed and the free end pulled out with ev tension as the swift, or turnatable revolve. Over-winding should be avoided at all times to obviate kinking. Coils m also be unwound by securing the free outside end of the rope and then rolling the coil along the ground; care bein taken at all times to ensure that the coil is held firmly together, avoiding tight coils or kinks.
