🔍 Key Concepts

• Types of securing devices used on Ro-Ro vessels (wire rope vs chain vs webbing/straps) • Which devices are typically matched with wire rope lashings in cargo securing manuals • Difference between devices made for chain and those made for webbing/strap lashings

💭 Think About

• First, sort each option by what material it is most commonly used with: chain, webbing/straps, or wire rope. • Ask yourself which devices are specifically designed to work with wire rope, including how they grip and tension the rope without damaging it. • Eliminate the options that are clearly associated with chain lashings or fabric/webbing lashings rather than wire rope.

✅ Before You Answer

• Verify which device is identified in Ro-Ro cargo securing guidance as being used with wire rope lashings. • Check which option name is typically paired with chain lashings and rule that one out for this question. • Confirm that buckle- and ratchet-type devices are more commonly associated with webbing/strap lashings, not wire rope, in standard Ro-Ro practice.
