When searching the Internet for wire rope, it is not hard for a person to become overwhelmed when choosing materials, sizes, and rope structures. Taking time to shop for ideal ropes saves users money and time. It also drastically increases safety. For safety, you can also consider accessories like wire rope slings or other rigging supplies.
There are five primary considerations that people should make when weighing factors that affect rope selections.
What strength-resistance to breaking is necessary for your applications? Your wire rope needs to be strong enough to handle the maximum potential load. Understanding what you are lifting will significantly determine which rope will work for you. Weak ropes are known to break, and ropes that are too strong add unnecessary weight and costs.
What resistance to fatigue bending do you need? Fatigue is caused as a result of ropes being repeatedly bending around sheaves and drums. If high fatigue is a factor, consider using a wire rope that is made of many small wires.
What resistance to vibrational fatigue does your application require? Energy gets absorbed at the tangent points or end fittings. Considering this element of application will allow ropes to work optimally for prolonged periods.
Do you need resistance to abrasion? Ropes that are constructed with many small wires are not ideal for resisting abrasion. Abrasion occurs as ropes are dragged over the ground or other hard surfaces. Consider ropes that have only a few and large wires.
Do you need crushing resistance? It is common for wire ropes to encounter crushing forces during normal daily operations. Ropes that cannot withstand crushing get distorted and flattened. When flattened or distorted, the ropes are considered permanently broken and require immediate replacement.
