🔍 Key Concepts

• Wire rope vs. fiber rope (hemp/manila) – which is more sensitive to improper handling and needs more careful maintenance? • Bending radius / sheave diameter – what general relationship is usually recommended between sheave size and wire rope diameter? • Typical care practices – how often is lubrication really needed, and are metal sheaves always lined?

💭 Think About

• Ask yourself: which option reflects a general principle of handling and preserving wire rope life, rather than a very specific number or procedure that might vary? • Compare how easily damaged wire rope is compared with hemp or manila rope when kinked, crushed, or run over sharp edges. • Think about maintenance: would once-a-year lubrication be enough for wire rope that may be working in a salty, wet, or dirty environment?

✅ Before You Answer

• Check which statement matches standard good practice in industry, not just a possible or occasional practice. • Eliminate choices that give overly exact figures or rigid schedules that are likely to depend on conditions and manufacturer recommendations. • Decide which option reflects the fact that wire rope is strong but more susceptible to internal damage that isn’t easily seen, and therefore needs particularly careful handling.
