chains will
provide smooth, efficient operation and, in turn,
extended chains and conveyor life. It is, therefore,
necessary to consider the factors that influence a "good"
maintenance program. Namely: 1) Proper installation 2)
Good lubrication 3) Cleanliness 4) Periodic Inspection
and 5) Repair and Replacement of worn components.
INSTALLATION
Before installing chain:
1. Check conveyor for flatness and obstructions.
2. For bevel design sideflexing chains, make sure outer
wear strip of each curve is about 1/32" lower than
inside wear strip to keep chain from rising up on the
outside.
3. Check sprocket alignment.
4. Pull a short (about three feet) section of chain through
LUBRICATION
of tight clearance. Make sure TAB chains have plenty
of clearance, especially on the inside of curves.
5. Rework conveyor to remove obstructions and provide
proper chain clearance.
6. Install the chain.
CAUTION: Install chain in 10 - foot sections, making
all connections on the conveyor frame. Thread
chain onto conveyor carefully to avoid twisting and
possible damage to the chain. Make sure all chains
except, 864, 1874 and 1873 are facing in the correct
direction for travel as indicated on the bottom or
side of the chain.
Start up conveyor and inspect according to checklist on
page 18, Multiflex. Correct any problem areas. Frequent
inspection and adjustment is recommended during the
run - in period to avoid any problems.
LUBRICATION
S881, S881TAB, SS881, SS881TAB, 1874 AND
SS1874 conveyors should always be lubricated.
Whenever the application permits, lubrication is
recommended. It not only reduces friction, thereby
reducing chain tension, but it also greatly improves the
wear life of chain and wear strips. Be sure the lubricant
coats both the chain and wear strip mating surfaces.
This is especially important on sideflexing chains and it
is sometimes necessary to apply the lubricant at the
entrance of the inside curves.
If lubrication is not compatible with the application, a
brief break - in lubrication application is beneficial. Apply
a light mineral oil to sideflexing chains prior to
installation. Also, apply oil to TableTop® base roller
chains prior to installation.
Some types of lubricants an lubrication methods are
described here:
TYPES OF LUBRICANTS
A. Oil Base Lubricants - These are vegetable or mineral
oils which offer high lubricity and coat the corrodible
chain parts. They should be used whenever practical
on all metal chains.
B. Water Soluble Lubricants and Soaps - These are
excellent lubricants and many of them help clean the
chain. Since the water is the conveying medium, they
are primarily suited for chains having corrosion resistant
parts or those with corrosion resistant top plates.
C. Water - Can be used as a lubricant although it is not
as effective as other types. If water is used as the
lubricant for plastic chains, sliding on a stainless steel
pan, the drag on the chain may be increased since a
thin film of water must constantly be sheared.
METHODS OF LUBRICATION
A. A central plumbing station meters lubricant under
pressure to locations through piping arrangement.
B. Sideflexing chains may be lubricated effectively by
applying the lubricant directly to the thrust surface below
the top of the flight as the chain enters the curve.
C. The lubricant drips onto the chain from an overhead
storage tank.
D. Bar soap with dripping water applied directly to the
chain.
E. The return chain strand runs through a pan of
lubricant.
F. The return chain contacts wheels of porous material
which rotate in a lubricant supply tank.
