WE ARE FOCUS ON SAFETY AND SECURITY

Sling Knowlegde

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. if the sling will be exposed to chemically active environments during use Please contact with our
  • temperatures will affect chain slings.If the working temperatures beside -20°F -400°F (204°C) please contact with qualified peason or factory
  • Never field weld or repair a chain sling. Chain slings should only be repaired by a qualified repair facility

INSPECTION

OSHA and ASME safety standards require the user to conduct:

  1. a) Frequent Inspections: A visual inspection for damage, which should be performed each day the sling is used.
  2. 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 or any dimension is worn more than 10% from the original dimension. Chain should be removed from service
  • 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 befollowed.

  • 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
