Chain Slings - Technical & Usage Information

Basic Inspection Criteria For Chain Slings

  1. Daily check for visible faults in links or hooks.
  2. At least twice a year:
    • Clean slings prior to inspection.
    • Hang the chain sling up or stretch the sling out on a level floor. Remove all twists. Measure the length. Discard if sling has been stretched.
    • Make a link-by-link inspection.
  3. Once a year:
    • We recommend to have the chain slings proof tested to twice the WLL and re-certified.
    • It is important to inspect chain slings and to keep a record of individual chain inspections.
  4. Remove from service if you detect:
    • 10% or more wear on individual links or contact points on any hardware
    • 5% elongation of individual chain links
    • chain link wear exceeding the values given in table below.

Lifting Practices Checklist:

  • Find out load weight before lifting.
  • Lower working load limit if there may be severe impact.
  • Balance the load to avoid over-stress on one sling leg or the load slipping free.
  • Pad sharp corners to prevent bending links.
  • Replace broken safety latches.
  • Reduce the chain capacity when using chain in temperatures above 400°F.
  • Keep hands and fingers from between load and chain.
  • Store chain slings on racks in designated areas.
  • Do Not Jerk the load when lifting or lowering the sling. This increases the actual stress on the sling.
  • Do Not Drag the sling.
  • Do Not Splice the sling by inserting a bolt between two links.
  • Do Not Try to Repair the sling unless you are properly trained. Use only original spare parts.
  • Do Not SHORTEN the sling with knots.
  • Do Not Force a hook over a link.
  • Do Not Use homemade connections. Use only attachments designed for the chain.

How to Order Chain Slings

Warning: Never Exceed Working Load Limit!

Type of Sling: Select the proper type of attachments from the illustrations in this catalogue.

Size: Determine the working load limit required, then check our catalogue for the size of chain needed.

Reach: Decide upon the overall length (bearing point of master link to bearing point of fitting).

Angle to the Load: Estimate the proper angle between the leg of the sling and the load during operation.

Sling Code: Use the following table to identify the sling you want.

First Symbol (Sling Type)

S = Single Leg
D = Double Leg
T = Triple Leg
Q = Quadruple Leg
*Add an “A” to the beginning for an adjustable chain sling

Second Symbol (Master Link)

O = Oblong Master Link (Recommended)
P = Pear Shaped Master Link (Upon Request Only)
*Replace master link symbol with hook symbol for single leg slings

Third Symbol (Hook Type)

S = Sling Hook
G = Grab Hook
F = Foundry Hook
SH = Self Locking Hook (specify type)
H = Hammerlock

D.O.S (Size) X (Reach)

NOTE: All chain slings are made to customer specifications and are therefore a non-returnable item. Please ensure all sizes and measurements are correct before ordering.

NOTE: The Pear Shaped Master Link and the Master Ring are not recommended but are available on request. Due to its geometry you must use a larger material diameter Master Ring when selecting a sling with a Master Ring as opposed to one with an Oblong or Pear Shaped Master Link.
