What is the Type IV connector link's rated capacity, and what is its primary use?

• A. 10,000 lbs, used to connect sling to helicopter
• B. 12,500 lbs, used to construct a 3 ft apex ring
• C. 5,000 lbs, used for tie-downs
• D. 15,000 lbs, used for crane hook

Answer: (B)

In sling-load rigging, hardware like connector links are matched to specific tasks and have defined load limits. The Type IV connector link is rated for 12,500 pounds, and its primary use is to build the apex ring that ties the lift lines together under the helicopter. That apex ring serves as the central connection point for the multiple sling legs, distributing the load evenly and helping maintain stability and balance during the lift. The 3-foot length of the apex ring is chosen to provide the right separation between sling legs, which helps keep load angles within safe ranges, minimizes excessive tension on any single leg, and ensures there’s enough clearance from rotor wash and aircraft structure. Other stated uses or ratings don’t align with this standard role in apex-ring construction, which is why this option is the correct pairing of capacity and purpose.
