General Overview, Industry Guidelines, and Liftex® Recommendations for Sling Inspections

- ASME B30.9
- WSTDA Recommended Standard Specifications

Frequency of Inspection:

Initial: Before any new or repaired sling is placed into service, it shall be inspected by a designated person to ensure that the correct sling is being used, as well as to determine that the sling meets the requirements of industry specifications. 

Frequent: A visual inspection shall be performed by the user or designated person prior to each use of a sling.

Periodic: A complete inspection for damage shall be performed  periodically by a designated person. Frequency of periodic inspection is based on frequency of use, severity of service conditions, experience gained on the service life of slings used in similar applications.  At minimum, frequency of periodic inspection shall be annual.

Written or electronic records of periodic inspections shall be maintained for each individual sling.

Liftex® strongly advises that slings displaying damage and subject to repair be evaluated by the manufacturer for suitablility of said repairs.  Damaged flat web slings should never be repaired.  Hardware from damaged web or round-slings may, subject to inspection of said hardware, may be salvaged and re-webbed.  Damaged components, sections or links of chain slings often times can be replaced and the sling put back into service.  Any repairs shall be evaluated and performed by the manufacturer.  Any repaired sling shall be proof-tested and documented prior to being put back into service.
