At the end of this module, you will be able to:
- Identify safety guidelines when working with wire ropes
- Describe steps to break in a wire rope
- Define maximum working load
- Describe the importance of wire rope inspections
- Describe hot to recognize wire rope hazards
The following key questions are answered in this module:
What personal protective equipment should be worn when working around wire ropes?
When working around wire ropes, one should wear: heavy leather gloves to protect your hands from cuts, abrasions, bruises, and rop burn, steel-toed shoes, to protect your feet from dropped loads or equipment, a hard hat, eye protection, and hearing protection.
What are ways to improve safety while working with and around wire ropes?
You can improve safety by: selecting a wire rope to match the conditions it will experience during use; only use wire ropes for jobs they are intended for; properly maintain all equipment the rope is being used with; never lubricate a rope using heavy grease, used engine oil, or any other lubricant that might corrode or damage the rope; always break in a newly installed wire rope; keep tension on the rope and never allow slack when a load is applied; and never overload a wire rope.
Why and how do you break in a wire rope?
Breaking in a wire rope allows the strands and wires within the rope to settle and align properly with one another. To properly break in a wire rope, run the rope with no load attached through the rope's entire operating cycle. Keep tension on the rope while doing this so that no slack or kinks develop. hen, apply a light load equal to about 10 percent of the working load limit to the rope and run the rope through its entire operating cycle again at a slow speed.
What are some of the conditions that can cause wire ropes to become dangerous?
Immediately notify your supervisor if you see: Abrasion or wear, bird caging starts occurring, broken wires start to appear, heat damage, kinking or bending, high stranding, corrosion, or crushed wire starts occurring.
Below is a transcript of the video sample provided for this module:
There are many conditions that can cause a wire rope to become dangerous. Immediately notify your supervisor if you see abrasion or wear. This can occur during the normal life of the rope. If the diameter of the outside wires has been reduced by more than 33%, the rope should be taken out of service. Bird caging. This is when the rope strands have become separated creating a bird cage effect. Bird caging is caused by sudden release of tension and greatly weakens a rope. Broken wires. Broken wires can occur within the rope or on the surface. The internal breaks are harder to find, but are very dangerous. Surface breaks can be spotted visually or detected by running a cloth over the surface to find snags.
