🔍 Key Concepts

• Galvanizing and how it affects the flexibility and fatigue life of wire rope • Difference between standing rigging (fixed) and running rigging (moving over sheaves/drums) • Where wire rope is constantly bent over sheaves or drums versus mainly under steady tension

💭 Think About

• Which of these uses will cause the wire to repeatedly bend and move over sheaves or drums during normal operations? • Which applications are mostly static or lightly adjusted and spend most of their life under steady tension, not cycling? • How does a zinc coating (galvanizing) behave when the wire is frequently flexed—does it help or can it crack and damage the rope?.

✅ Before You Answer

• Identify which choices are primarily standing rigging (fixed support) and which are running gear (moving frequently). • Ask: In which option does the wire rope most often pass over blocks/sheaves under load? That situation is more sensitive to galvanizing problems. • Verify which application requires maximum flexibility and fatigue resistance, where a stiff galvanized coating would be least desirable.
