Do not use more than how many parts of a line when using fiber blocks?

Do not use more than how many parts of a line when using fiber blocks?

• A. 6
• B. 10
• C. 8
• D. 12

Answer: (C)

In rigging with fiber blocks, the number of line parts determines how the load is shared among the rope segments and how much stress each part must carry. Fiber rope blocks are rated for fewer parts than steel blocks because fiber rope is more sensitive to heat, wear, and bending friction. Limiting to eight parts keeps the rope within its safe strength and life, reduces heat buildup from friction inside the block, and minimizes wear on the rope and grooves. Using more parts would push the rope beyond its rated capacity for this equipment, risking premature wear or failure. If you were using steel blocks, the limit would typically be higher, but for fiber blocks eight parts is the standard maximum.
