Series 2 Chain Conveyors
Drag Chain Assembly Installation
All chain supplied with new conveyors will be
installed in a similar manner, regardless of type.
Correct total chain length has been determined for
your installation by GSI. The conveyor drag chain
is shipped in approximate 10 foot lengths with an
additional pre-cut short section if necessary (refer
to packing list). If welded chain (WH132, WH155
or WH157) has been supplied with the conveyor,
a minimum of five (5) feet of chain with cottered
pin connectors will be supplied. These pin con-
nectors and links may be removed as necessary for
chain take-up. The chain may be installed at any
time during conveyor assembly.
It is recommended however, that you position the
chain over the slide rail returns and the sprock-
ets in the head and tail assemblies. The UHMW
wear pads should be in front of the welded chain
flights in the direction of chain travel (see dia-
gram below). Connect chain lengths together
with connecting links and/or pins.
Installation
Rotate the chain, now on the sprockets, at least
one complete revolution. Check to see that the chain
and its wear pads are not catching on flanges or
rubbing on the trough liners. Ensure a “break-in”
period whereby the chain is allowed to run and
seat itself. After running it for an adequate period
of time stop the machine, disconnect and lockout
the power source. Retighten as necessary and re-
move any excess chain portions. Repeat this pro-
cess as necessary.
Tighten the drag chain assembly using the take-up
screws located on each side of the tail section or on
the take-up head. The chain should be able to be
lifted slightly when sufficiently tightened. After the
chain is tight, check that the head and tail shafts are
square to the box sides. If the shafts are not square,
loosen the tighter of the two take-up screws until
the shafts are square. Lock the take-up screws by
tightening the jam nuts.
