Chain Lubrication
Running the chain dry will substantially shorten its life. Oil must be reapplied on a
regular basis to ensure the chains maximum life is achieved.
The frequency of this operation is at the discretion of the user and essentially depends
upon the working conditions and the workplace environment.
Ensure that the chain is slack during the lubrication process so that the lubricant
can flow between the chain link plates and pins.
It is recommended that the lubricant used on the chains has the following properties:
Satisfactory corrosion protection and lubrication
Ability to penetrate through / under water
Continuously viscous after application
Good adhesion properties
Layer thickness and protective film able to withstand later aggression (rain / hail
etc.)
The following lubricants (available in an aerosol can) are recommended:
Fuchs anticorit bw366
Molykote mkl-n
Kluber structovis bhd 75s
Where chains are encased in dirt and dust the lubricant will be prevented from flowing
to the vital load bearing contact areas of the chain between the link plates and pins.
It is essential with leaf chains that all dirt and debris is removed prior to lubrication.
Recommended jet equipment cleaning method for leaf chain:
The following method is recommended when the use of jet cleaning equipment cannot
be avoided in
leaf
chain
maintenance
:
1.
Cleaning
- Clean the
leaf
chain
using steam or hot water only. Absolutely no
additives should be used.
2.
Compressed Air
- Immediately after cleaning the
leaf
chain
, all water should
be removed both from the surface and from inside the
chain
joints using high
pressure compressed air. The articulating links of the
chain
should be moved
several times during this process.
3.
Re-lubricating
– Make sure that the
chain
is slack and then spray with a
preservative and lubricant. Articulate the
chain
several times so that the
lubricant penetrates the
chain
joints.
Caution
The chains must be kept lubricated at all times.
