a.
See Section 5.1.6 for instructions on slat installation.
5.
Join the chain sections with a connecting link, then install the chain mounts over the connecting link
section. See Figure 8.
6.
Once the chain is installed on top of the sorter, use the drive sprocket to help pull the chain around.
7.
Two options to turn the drive sprocket manually are:
a.
The flat on the drive shaft (use a 1-
1/8” o
pen end wrench with a cheater bar or other long
handle extension)
b.
Remove the fan cover and rotate the fan of the drive motor by hand (this method is slower, but
it requires lower torque due to the mechanical advantage of the gearbox)
The drive must be locked out during chain install
—
do not use the drive motor to
advance the chain during installation. Death or serious injury could result.
8.
Attach ropes to the free end of the chain to help pull the chain through the catenary (force should
be transmitted through the drive sprocket; the ropes are to correctly guide the free end).
DO NOT pull on the slats or chain mounts. Damage to the slats or chain mounts could
result. Fasten any pulling devices (winches, come-alongs, etc.) directly to the chain,
with the use of a suitable spreader bar to ensure the force is exerted directly along
the length of the chain.
There will be, by design, one matched pair of chains that is a shorter length than the
others. This pair has been factory-cut to the appropriate length for the sorter
installation. As with all matched chain pairs, this pair must be kept directly across
from each other.
9.
Install the short length chain pair last.
10.
Depending on the sorter length and the chain weight, making the last chain splice may require the
use of come-alongs, ratchet straps, or other mechanical pulling devices to generate enough slack to
insert the last connector link.
11.
Apply no more than 800 lbs of pulling force to each chain end (1600 lbs total).
12.
If needed, adjust the position of the tail shaft (only if the chain cannot be assembled otherwise) to
gain extra slack. Ensure the tail shaft remains square to the sorter frame. See Figure 25 and Figure
26 in Appendix 3.
13.
Once the chain installation is complete, install the
“
missing bearing
”
sensor on the first divert of the
sorter.
a.
See Figure 21, Figure 22, and Figure 23 in Appendix 3 for drawings showing the mounting
details, location, and alignment of the pin sensor
and “missing bearing”
sensor.
b.
The “missing b
earing
”
sensor must be positioned 4-
1/2” behind
the pin sensor.
c.
See Section 6.2 for detailed troubleshooting information on the
“missing
bearing
”
sensor.
