  • Chain slings provide excellent performance in harsh environments. When using chain for overhead lifting, an alloy grade, either grade 80 or 100, is recommended.  
  • We offer domestic & foreign chain in stock at locations across the US 

Chain Slings

Important Chain Information: 
  • Other grade chains and components can be appropriate for specific applications with unusual requirements. It is critical that the fittings used for sling assembly be of like material. A sling identification tag with the size, grade, rated capacity, and reach is required by OSHA regulation. Per ANSI/ASME B30.9. Some things you need to keep in mind: 
  • Safe Working Loads 
  • Determine the safe working load of slings, chains, accessories, and rigging equipment before use. The safe working loads of slings must not exceed the rated capacities. For types of slings not included in these tables, follow the manufacturer’s recommended safe working load for the specific angle of loading, provided that you maintain a safety factor of five. 
  • Job-Fabricated Rigging Hardware.  
  • A professional engineer must design and certify use of any job-fabricated rigging hardware and test it at twice the rated safe working load or in accordance with applicable standards. 
  • Use, Repair and Maintenance.  
  • The use, repair, and maintenance of ropes, chains, slings, and rigging accessories must conform to the manufacturer’s written instructions. Test repaired slings and accessories at twice their rated load before use. 
  • Inspection.  
  • Make frequent and periodic inspections. Immediately remove defective equipment from service. 
  • Frequent Inspections.  
  • The user must inspect rigging equipment before each shift. 
  • Thorough Periodic Inspections.  
  • A designated person must thoroughly inspect rigging equipment and maintain a written record. The field location must determine the frequency of the periodic inspection on the basis of use, severity of service conditions, nature of the lifts, and experience on the service life of slings used in similar circumstances. Conduct inspections periodically and at least once every 12 months. 
  • Special or Infrequent Service. 
  • For slings that are used infrequently, inspect before each use. At the time of use, document the inspection. 
  • Removal From Service.  
  • Routinely inspect chain, wire rope, fiber, synthetic webbing, and sling hooks. Remove from service if any are deformed, damaged, or otherwise do not meet inspection criteria and are not safe for use. Cut up and discard slings removed from service due to defects or plainly mark them as being unfit for load-bearing service. Do not repair cracked, broken, or bent end attachments. Replace them. 
  • Protection.  
  • Appropriately protect slings from sharp, rough, or square corners to prevent damage to the strands, wires, or links. Properly store slings when not in use to protect them from damage. 

Types of Chain Slings

ALLOY CHAIN – the components used in welded or mechanical slings meet or exceed all existing OSHA, Federal NACM, ASTM and ISO chain specification requirements. Certificates for OSHA and internal record requirements are available upon request.
The WORKING LOAD LIMITS are based on a 4:1 design factor required by the International Standards Organization (ISO). Should an extreme load actually deform the chain, it will stretch (elongate) a minimum of 15% before breaking. An embossing of the chain link allow for easy identification of Alloy Chain.
While Grade 80 is the more commonly used, Grade 100 usage is increasing.

We maintain the specification of each welded sling on file under a unique registration serial number for inspection or should the chain require servicing. The rated capacity of a welded sling cannot be altered since its welded construction prevents on site tampering. Welded slings can be fabricated to your specific needs and are available with a variety of special end attachments.
This flexible system saves on costly down time, since they can be repaired or altered on site. Components are manufactured under rigid quality control standards and meet or exceed the capacity of Grade 80 Chain.
Every component has forged marking indicating the alloy chain size to be used with it.

The following information is required to process an order or an inquiry:

• SIZE & GRADE: This is specified by the size of the material from which the chain is made and is dependent upon the working load limit required.
• REACH: This is the length, including attachments, measured from bearing point to bearing point.
• TYPE: Select and specify the proper type of sling from the list below. (ex. S – Single O – Oblong Link S – Sling Hook).
• ATTACHMENTS: Unless otherwise specified standard master links and hooks as given herein will be used. When other than standard attachments are required, we should be given a complete description or a drawing of the requested substitute.


• ASME B30.9.1 requires all new components of alloy lifting chain assemblies to be proofloaded prior to their initial use.
• ASME B30.9.1 requires all repaired alloy lifting chain assemblies incorporating previously used components to be proofloaded prior to their initial use.
• When hot galvanized chain is specified, the recommended work load limits MUST be reduced.
• Please refer such inquiries to our nearest Branch Manager.
