🔍 Key Concepts

• Container lashing systems and how solid bars differ from wire rope lashings in strength and stiffness • Effect of lashing strength on permitted stack weight and height • Why stronger or stiffer lashings might change allowable stack height rather than require reductions

💭 Think About

• Think about whether a solid bar is generally stronger and less elastic than a wire rope of comparable size, and what that means for supporting higher container stacks. • Ask yourself: if a lashing system can safely withstand higher forces, would you normally need to reduce or could you potentially increase the stacking arrangement? • Consider which choices talk about reducing limits and which talk about allowing more when using a stronger lashing method.

✅ Before You Answer

• Verify which lashing (solid bar vs wire) is typically considered stronger and less flexible in container securing practice. • Check which option logically matches the idea that stronger lashings can safely handle greater vertical stack loads. • Eliminate any options that incorrectly suggest you must weaken your stacking plan when you upgrade to a stronger lashing system.
