u
If, as a result of wear and tear, the nominal thickness of a chain link is < 90 % (see Figure 2).
u
Damage (cuts, notches, grooves, cracks, discoloration due to heat, excessive corrosion,
bent or twisted links, or other defects).
u
Signs of widening (excessive throat opening) or deformation of hooks.
The widening must not exceed 10 % of the nominal measure; if hooks with safety catch are used,
the catch must not become disengaged.
•Inspections are to be recorded and proved in writing.
• Each individual part of the chain sling has to meet the requirements of DIN 5687,
DIN 5688 Part 1 and DIN 7541.
• Individual chain links are not to be replaced - replace complete legs instead.
• Any individual parts which are broken, noticeably deformed, seriously corroded, or show
deposits which cannot be removed, are to be discarded or replaced.
• Minor notches or furrows in parts of chain slings may be evened out if the remaining material thickness
in this point is > 90 % of the nominal thickness and no sudden cross-sectional change is noticeable.
• Welded chain slings may only be repaired by the manufacturer.
• If welding operations have been performed on chain slings, each individual leg which has
been repaired has to be tested subsequently with twice the SWL value.
• Replacement of mechanical connection links requires no load testing if the individual part testing is
certified.
u
CE Label for completely assembled chains.
u
The label guarantees that the technical requirements of the EC guideline have been met.
It is prohibited to assemble chains and components of different grades.
