Sling Selection

Select a sling having suitable characteristics for the type of load, hitch and environment to which it will be subjected.

  • Sling Capacity: Determine weight of load
  • Sling Type: Select a sling of suitable design for the type of hitch to be used.  Where there is no reason to use another type, endless type is recommended.  The endless type is more economical and gives longer service life because of wear rotation
  • Sling Width: If width is not a consideration because of load crushing or other reasons, use the narrowest sling that is rated to handle the load.  Generally, a narrower sling is more economical.
  • Sling Length: Choker slings with metal end fittings must be sufficient length to assure that choking action is on the webbing.  Basket hitch slings must be of sufficient length to prevent overstressing of sling legs due to high sling leg angles.  Consider the advisability of one complete wrap around the load for choker hitch slings, thus providing a good grip on load
  • Sling Body Ply: Body ply indicates the number of web thickness in the body of a sling.  A rule of thumb is that for a given sling you can double the rated capacity by doubling the plys.  For example a 1″ two ply sling would have the same capacity as a 2″ single ply
  • Material: Nylon vs. Polyester – Nylon is slightly more wear resistant and has better shock absorption qualities than polyester.  Polyester should be used where acids are present and where minimum stretch of the sling is desired
Sling Angle and Sling Load Chart

Sling angle is the angle measured between a horizontal line and the sling leg or body.  This angle is very important and can have a dramatic effect on the rated capacity of the sling.  As illustrated when this angle decreases, the load on each leg increases.  This principle applies whether one sling is used to pull at an angle, in a basket hitch or for multi-legged bridle slings.  Sling angles of less than 45 degrees are not recommended.

Actual Sling Capacity = Factor X Rated Capacity

Chemical Resistance

  • Nylon and polyester can be used with alcohols, cleaning solvents, halogenated hydrocarbons, crude oils, lubricating oils, soap and detergents, water and seawater
  • Do NOT use nylon with acids or dry bleaching agents
  • Do NOT use polyester with aldehydes or ethers
