6 Maintenance
Carry out maintenance (lubrication, cleaning, inspection and tests, removing burrs) as described in this chapter and according to
the applicable local legislation.
6.1 Lubrication
•
Grease the contact areas (A). This extends the lifetime of both the NEMAG
Quick Release Link and the NEMAG Rope Pear Socket.
•
Use EP3 or EP4 grease (lubricant for high-pressure contact surfaces).
•
Apply grease after every 24 hours of use.
NOTE
Do not grease the NEMAG Rope Pear Socket when it is used in an environment with large quantities of abrasive particles. For
example during transshipment of alumina or other abrasive / dusty ores.
6.2 Cleaning
During use, particles that stimulate wear can become embedded in the lubricant. Therefore, regularly clean the bow of the NEMAG
Quick Release Link.
6.3 Visual inspection
Visually examine the NEMAG Quick Release Link for defects after every 200 hours of use.
6.4 Removing sharp hard points and burrs
Through contact with other equipment, burrs or small bumps can occur on the edges of the contact surfaces of the locking piece.
This can make it difficult to slide the locking piece on the ‘C’ section. Use a file to remove these burrs or small bumps, until the
locking piece functions correctly again, as described in chapter 5.
WARNING
When you remove any defects, make sure that the play between the ‘C’ section and the locking piece, and the overall wear of
the ‘C’ section, do not exceed the values that are given in chapter.7.
6.5 Magnetic Particle Inspection (MPI)
•
To avoid failures that are the result of fatigue cracks, the NEMAG Quick Release
Link must undergo a Magnetic Particle Inspection (MPI) after at least every
125,000 cycles at safe working load (SWL).
•
Do the MPI at the areas that are shown in the illustration.
•
Do the MPI at the intervals that are given in section 6.6.
•
If required by the applicable local legislation, test the NEMAG Quick Release
Link after inspection
