With each application, your choices of wire ropes can be many. How do you know which one works best for you? Ropes include a combination of properties that give them specific performance abilities. Before you choose, it pays to look closely at each rope’s special properties.
NO SINGLE WIRE ROPE
CAN DO IT ALL
All wire ropes feature design characteristic trade offs. In most cases, a wire rope cannot increase both fatigue resistance and abrasion resistance. For example, when you increase fatigue resistance by selecting a rope with more wires, the rope will have
less abrasion resistance because of its greater number of smaller outer wires.
When you need wire rope with greater abrasion resistance, one choice is a rope with fewer (and larger) outer wires to reduce the effects of surface
wear. But that means the rope’s fatigue resistance will decrease. That’s why you need to choose your wire rope like you would any other machine. Very carefully. You must consider all operating
conditions and rope properties.
THE BASIC PROPERTIES
OF WIRE ROPE
How do you choose the wire rope that’s best suited for your job? Following are the most common properties to be considered when selecting a rope for an application.
STRENGTH: Wire rope strength is usually measured in tons of 2,000 lbs. In published material, wire rope strength is shown as minimum breaking
force (MBF) or nominal catalog)
