Synthetic Flat Webbing Sling ASME B30.9

ASME B30.9 is a safety standard set forth by the American Society of Mechanical Engineers (ASME) that specifically pertains to "Slings." In this context, slings refer to various devices used to lift and handle loads, including Synthetic Flat Webbing Slings.


A Synthetic Flat Webbing Sling is a type of lifting sling made from a durable synthetic material, typically polyester, nylon, or polypropylene. It is designed to be lightweight, flexible, and easy to handle while offering high strength and load-bearing capacity. Synthetic webbing slings are commonly used in a variety of industries for lifting and moving various types of loads, such as machinery, equipment, and construction materials.


Key features and considerations for Synthetic Flat Webbing Slings under ASME B30.9 include:

  • Design and Construction: These slings are made of flat webbing material, woven or stitched together to form a loop at each end. The webbing material is carefully selected for its strength, flexibility, and resistance to abrasion and UV degradation.
  • Load Capacity: The load capacity of Synthetic Flat Webbing Slings varies based on their width, material, and construction. They are usually color-coded to indicate their Safe Working Load (SWL) or Working Load Limit (WLL) as per ASME standards.
  • Markings and Labeling: Synthetic webbing slings must be clearly marked with information about their load capacity, working length, manufacturer's identification, and any other relevant information to ensure proper and safe use.
  • Safe Usage: ASME B30.9 provides guidelines for the proper use, inspection, and maintenance of slings, including Synthetic Flat Webbing Slings. It is essential to follow these guidelines to ensure safe lifting operations and to prevent accidents or equipment damage.
  • Inspections: Regular inspections of the slings are required to identify any signs of wear, damage, or degradation. Slings that show signs of wear or damage should be removed from service and replaced.
  • Use of Hardware: Synthetic Flat Webbing Slings may be used in combination with various hardware, such as hooks or shackles.
    The selection and use of appropriate hardware are essential to maintain the overall integrity and safety of the lifting system.

Complying with ASME B30.9 ensures that the proper procedures and safety measures are followed when using Synthetic Flat Webbing Slings, contributing to safer lifting operations and reducing the risk of accidents and injuries. Always consult the manufacturer's guidelines and ASME B30.9 standards to ensure the correct usage, inspection, and maintenance of synthetic webbing slings.
