System 10 Cam-Alloy Chain Slings

Inspection, Care and Proper Use of Chain Slings

Campbell welded chain products and components are designed and built for rugged lasting service. As with any quality product certain precautions and standards of treatment should be observed. Proper care will extend the useful life of the product.

INSTRUCTIONS REGARDING COMPONENTS & FITTINGS
Components, such as master links and hooks, should have at least the same working load limit (rated capacity) as the chain with which they are used. If not, the sling shall be rated to the capacity of the weakest component. Campbell offers a full line of Cam-Alloy® and Quik-Alloy® sling components engineered specifically to be compatible with our alloy chain products.

WARNINGS AND CAUTIONS
• The use of chain, slings, and components are subject to certain hazards that cannot be met by mechanical or manufacturing means, but only by the exercise of intelligence, care, and common sense
• Sling use is subject to the Occupational Safety & Health Administration (OSHA 29 CFR 1910.184) and American Society for Mechanical Engineers (ASME B30.9) safety standards, requiring the sling user to conduct safe working practices and perform inspections
• Do not exceed the working load limit of the sling or any component
• Chemically active environments may adversely affect chain slings. Do not use in highly acidic or caustic environments. Campbell should be contacted if the sling will be exposed to chemically active environments during use
• High and low temperatures will affect chain slings. Campbell should be contacted if temperatures below -20°F (-29°C) will be experienced. The attached Effect of Elevated Temperature on the Working Load Limit of Alloy Chain chart shows the reduction in strength that occurs when chain slings are used at or have been exposed to tempertures above 400°F (204°C)
• Never field weld or repair a chain sling. Chain slings should only be repaired by a qualified repair facility
• See other specific information under the Care, Inspection, and Proper Use sections

INSPECTION
OSHA and ASME safety standards require the user to conduct:
a) Frequent Inspections: A visual inspection for damage, which should be performed each day the sling is used.
b) Periodic Inspections: A complete link by link and component inspection. Periodic inspection intervals vary depending on sling usage and conditions, but must occur at least annually. Written records of periodic inspections are required. The slings should be inspected for the presence damage. The sling should immediately be removed from service if any of the following conditions are present:
• Missing or unreadable identification tag
• Cracks in the chain or any component
• Excessive nicks, gouges or wear. Chain should be removed from service if the thickness at any point on the link is below the value shown in the attached Cam- Alloy Chain Minimum Allowable Thickness chart. All other components should be removed from service if any dimension is worn more than 10% from the original dimension
• Stretched, bent, twisted, or distorted chain links or components
• Excessive corrosion
• Evidence of heat damage
• Evidence of field welding or weld spatter
• Any other condition which questions the integrity of the chain sling
• Any side movement of the Quik Alloy Coupling Link Pin could indicate excessive wear of the pin or link half and be cause for removal from service
• Depending on the severity of use and environment, individual Quik-Alloy components should be disassembled so that load pins may be thoroughly inspected

CARE
• Chain slings should be stored in a clean and dry area, preferably on a rack, in order to extend their life
• Chain slings should not be stored in areas where they would be subject to damage, corrosion, chemical attack, or extreme temperatures
• Clean slings periodically, as dust and grit can accelerate wear
• During use, chain slings should not be dragged over abrasive surfaces. Loads should not be rested on the chain sling to avoid damage

PROPER USE
To protect the operators, the load, and the sling, the following safe practices should be
followed. Campbell also recommends compliance with the OSHA and ASME safety
standard practices.
• Select a sling suitable for the load, type of hitch, angle of loading, and environment. The hooks and master links should be of a size to fit the intended connections
• Avoid shock loading
• Pad all sharp edges or corners in contact with the sling to prevent damage to either the sling or the load
• Balance the load to prevent shifting, to maintain control of the load, and to prevent overloading of any leg in a multiple leg sling
• Rig so that the load is properly seated in the hooks and master link. Avoid tip loading of hooks and side loading of master links
• Avoid twisting or kinking of sling legs
• Never knot chain legs
• Horizontal angles less than 30° should not be used without consulting Campbell or a qualified person
• For choker hitches, angles of choke greater than 120° should not be used without consulting Campbell or a qualified person. Choker hitches reduce the working load limit by 20% (See pages 186 & 187)
• For basket hitches, the minimum recommended diameter of the load is 10 times the nominal chain diameter Purchasers please note that all “Warnings and Cautions” apply to chain, components and fittings, as well as chain slings. Purchasers are responsible for conveying the “Warnings and Cautions” including the “Inspection, Care and Proper Use” section information to the end user. Campbell denies any liability for damage that results from use in excess of the working load limit or any abuse or misuse of the product. Any questions concerning the use of Campbell products may be directed to your Apex Tool Group Sales Representative or Customer Service.
