Wire Rope in Hoisting Services: Zinc Coated for Longevity

Is it true that wire rope used in hoisting services, involving constant bending around drums and sheaves, is usually zinc coated?

Answer:

True

Wire rope used in hoisting services, involving constant bending around drums and sheaves, is typically zinc coated (galvanized) to prevent corrosion and extend its lifespan.

Explanation:

The statement that wire rope used in hoisting service and subjected to constant bending around drums and sheaves is usually zinc coated is true. Zinc coating, also known as galvanization, is a common method used to protect steel wire ropes from corrosion, which is a critical factor when the ropes are used in applications involving repetitive movements and exposure to various environmental conditions. The zinc coating serves as a sacrificial layer, corroding in place of the steel it protects. This increases the longevity of the wire rope, making it a preferred choice for hoisting and other applications where durability is essential.
