Pipeline Single Loop Choker consists of a single piece of wire rope that forms a loop. This loop is passed around the load and then through itself, creating a choker hitch. When lifted, the choker belt tightens around the load, providing a secure grip.
1. Material • Wire Rope: Often galvanized or stainless steel for corrosion resistance. • Chain: Made from high-strength alloy steel / Mild Steel.
2. Size and Length • Diameter: Varies based on the load capacity, typically ranging from 1/4 inch to 1 inch or more. • Length: Customizable, with standard lengths ranging from a few feet to several dozen feet depending on the application.
3. Load Capacity • Working Load Limit (WLL): The maximum load that the choker belt can safely handle, usually specified in pounds or tons. This varies greatly depending on the material and construction. • Safety Factor: Often a 5:1 safety factor is used, meaning the breaking strength is five times the WLL.
4. Construction • End Fittings: Thimbles, hooks, or other fittings may be attached to the ends for ease of connection and to prevent wear on the sling. • Loops: Should be securely spliced or stitched to ensure strength and durability.
5. Standards and Certification • Compliance: Should meet relevant industry standards such as ASME B30.9 (for lifting slings), OSHA regulations, and others specific to the industry and region. • Certification: Slings often come with certification tags indicating load capacity, safety factors, and compliance with standards.
6. Environmental Resistance • Corrosion Resistance: For metal slings, particularly important in marine or chemically harsh environments. • UV Resistance: For synthetic slings, to prevent degradation from sunlight. Single loop choker belts are commonly used in industries such as construction, maritime, logging, and any field where heavy lifting and secure transport of materials are required.
