Hitches and Configurations

Vertical Hitch

• Configuration: One eye of the wire rope is attached to the hook, and the other eye is attached to the load[3].

Choker Hitch

• Configuration: One eye of the sling is attached to the lifting hook, and the second eye is looped over the first to create a noose or choke shape[3].

Basket Hitch

• Configuration: Both eyes of the sling are looped over the lifting hook, supporting the load from both sides[3].

Bridle Hitch

• Configuration: Involves more than one wire rope sling to equalize the load and maintain balance. This configuration is useful for loads with fixed lifting points[3].

Design and Construction

Wire Rope Composition

• Types: Wire ropes are categorized based on the number of wires in a strand and the number of strands around the core (e.g., 6×19, 6×37)[1].

Splicing Techniques

• Flemish Eye Splice: The wire rope is opened, and the strands are laid out into two parts, then looped in opposite directions and rolled back together with a metal sleeve fitting[5].
• Turnback Eye Splice: The rope is bent against the live portion to the free end using a steel or aluminum sleeve[5].
• Hand-Tucked Eye Splice: The shorter “dead” end is tucked into the longer “live” end of the wire rope[5].

End Fittings and Accessories

Thimbles

• Definition: U-shaped pieces that fit the wire rope to enhance strength and reduce stress on the eye.
• Uses: Prevent the hook or load from coming into contact with the wire rope and maintain the natural shape of the sling[3][4].

Frequently Asked Questions (FAQs)

What are the different types of slings used for crane operations?

Slings used for crane operations come in various materials and designs, each suited for specific tasks and environments. These include synthetic fiber slings made from materials like polyester, nylon, or K-spec, which are lightweight, easy to handle, and do not damage sensitive surfaces. Metal slings such as wire rope slings and chain slings are also common; wire rope slings are durable and resistant to abrasions, while chain slings are strong and can withstand high temperatures. Additionally, there are metal mesh slings and natural fiber rope slings, each with their own set of advantages and limitations[2][4][5].

How do you choose the appropriate sling for a lifting operation?

Choosing the right sling involves several critical considerations. First, you must assess the weight, shape, and nature of the load to be lifted. The lifting mode factor and the environment in which the operation will take place, including temperature and exposure conditions, are also crucial. The type of sling should be selected based on these factors to ensure the load can be lifted safely. For example, alloy steel chain slings are suitable for high-temperature environments and irregularly shaped loads, while synthetic web slings are better for delicate or sensitive materials. Always refer to the manufacturer’s guidelines and ensure the sling’s rated capacity matches the load’s weight[1][3][5].

What safety precautions should be taken when using slings for crane operations?

When using slings for crane operations, several safety precautions are essential. Before each use, visually inspect the slings for any damage such as cuts, burns, or excessive wear. Ensure that the sling is properly attached to the load and the crane hook, with the hook positioned directly over the load’s center of gravity to prevent tilting. Avoid kinking or shortening the sling with knots or other devices, and pad or protect the sling from sharp edges. Keep suspended loads away from obstructions and avoid dragging loaded slings along the ground. Only trained and competent personnel should handle slings, and they should follow standard hand signals to communicate with the crane operator[1][3][5].

How should slings be inspected and maintained to ensure safety and longevity?

Regular inspection and maintenance of slings are vital for ensuring safety and extending their lifespan. Before each use, conduct a visual inspection to detect any damage or wear. For synthetic web slings, check for burns, melting, charring, snags, rips, and broken stitches. For chain slings, look for elongation, crushing, deformation, or wear that reduces the diameter of the links. Any damaged sling should be removed from service immediately. Store slings in a clean, dry environment, away from direct sunlight and chemicals. Follow the manufacturer’s recommended maintenance schedules, and consider retagging slings if their identification tags are missing or unreadable, provided they pass inspection and proof testing[1][2][4].

What are the specific guidelines for using multiple slings in a lifting operation?

When using multiple slings in a lifting operation, it is crucial to follow specific guidelines to ensure safety and stability. The slings should be positioned so that the load is evenly distributed across their width, and the lifting point should be directly above the center of gravity of the load. Respect the angles indicated in the tables for multiple slinging to avoid unequal stress on the sling legs. For heavier loads, distribute the weight among more sling legs to maintain balance. If using more than two slings on a single hook, use a collector ring such as a link or shackle to ensure equal loading on the hook points. Always ensure that the slings are securely attached and that the crane operator is signaled correctly to avoid any mishaps[1][3][5].
