Series 2 Incline Chain Conveyors

Installation

PNEG-1187

All chain now supplied with new conveyors will be in-
stalled in a like manner, regardless of type. Correct
total chain length has been determined for your instal-
lation by the manufacturer. The conveyor drag chain is
shipped in approximate 10 foot lengths with an addi-
tional pre-cut short section, if necessary (refer to pack-
ing list). The chain may be installed at any time during
conveyor assembly.

It is recommended however, that you position the
chain over the center pan or slide rail return assem-
blies and the sprockets in the head and tail assem-
blies. The UHMW wear pads should be in front of
the welded chain flights in the direction of chain travel
(see diagram below). Connect chain lengths together
with connecting links and/or pins.

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 sides due to the sprockets not being cen-
tered within the box. Ensure a “break-in” period
whereby the chain is allowed to run and seat itself. Af-
ter running it for an adequate period of time stop the
machine, disconnect and lockout the power source. Re-
tighten as necessary and remove any excess chain por-
tions. Repeat this process 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. 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
adjuster screws until the shafts are square. Lock the
adjuster screws by tightening the hex nuts against the
cross-ways “C” channel.
