4. Operation
16 PNEG-1128 Chain Loop System without Controls
Operating the Chain Loop System (Continued)
Observe the following basic sequence for using the Chain Loop System to transfer grain from
storage bins.
1. Open the discharge gate above the withdrawal bin.
2. Open the discharge gate above the destination bin or truck-loading spout.
3. Start the Chain Loop drive motor. Station an individual at the control box to observe the amp gauge
of the drive motor.
4. Open the slide gate under the withdrawal bin a little at a time to make sure that the amperage does
not exceed the capability of the drive motor.
5. Close the discharge gate above the destination bin or truck when full. DO NOT SHUT DOWN THE
CHAIN LOOP DRIVE MOTOR AT THIS TIME.
6. Close the slide gate under the withdrawal bin.
7. Run the Loop System until all remaining grain in the tube has been returned to the withdrawal bin.
8. Shut down the drive motor.
9. Make sure to lock out the power source before leaving the work area.
Figure 4A
A sweep auger may be placed in the bin after all the grain has been removed that will gravity-flow
through the center well. Shut down and lock out all power to the Chain Loop System before installing the
sweep auger.
If intermediate bin wells are being used, they should be opened after grain has stopped flowing into the
center well and before the sweep auger is placed in the bin.
(See Figure 4B.) Shut down and lock out the
Chain Loop System before installing the sweep auger.
