With an 'improved plow' wire rope sling, the preferred D/d basket hitch ratio is?

• A. 10 to 1
• B. 25 to 1
• C. 5 to 1
• D. 50 to 1

Answer: (B)

In this type of hitch, the D/d ratio shows how big the load is compared to the rope diameter. A larger ratio means the rope forms a gentler bend around the load, distributing pressure more evenly and reducing wear on the rope. For an improved plow basket hitch, the preferred D/d is 25 to 1. This higher ratio helps prevent excessive compression and abrasion of the rope strands, improving safety and sling life. Ratios that are too small (like 5:1 or 10:1) concentrate pressure on the rope and can lead to faster wear or damage, while a much larger ratio (such as 50:1) isn’t typically required and doesn’t add meaningful safety beyond the 25:1 guideline.
