What is the main disadvantage of lace reeving?

• A. The blocks tilt toward each other
• B. The rope wear is reduced
• C. There is less friction
• D. The blocks stay perfectly aligned

Answer: (A)

Lace reeving creates lateral forces that pull the blocks toward each other. The lace arrangement causes the rope tensions on the sides to have inward components, and those inward components add up, tilting the blocks toward one another rather than keeping them aligned. This misalignment can lead to uneven loading on the pulleys and hardware, increased wear, and more maintenance issues. Since the blocks are not kept perfectly aligned, options suggesting reduced rope wear, less friction, or perfect alignment don’t fit.
