4. General Information
Bulk Feed Tank Assembly Manual General Instructions
First, read the assembly manual completely before starting to assemble the Bulk Feed Tank. Check the
shipment with the packing list to be sure there are no shortages.
1. Decal protective mask must be removed when assembling tank. Mask may become difficult to
remove if left exposed to sunlight.
2. Vertical seams must be staggered on all sidewall rings.
3. When legs extend up 2 rings, the leg holes must be in alignment in the bottom 2 rings.
4. All hopper seams and the hopper collar use truss head bolts. The heads of the bolts must be on the
inside of the tank.
5. All bolts are to be tightened from the nut side only. Do not allow bolt heads to spin.
6. Hex head bin bolts are used on all sidewall and roof seams with the bolt heads on the outside of
the bin.
7. Hex head bolts are to be used on all leg to sidewall connections with the bolt heads on the inside of
the tank.
8. Drift punches can be used to align holes.
9. All vertical sidewall sheet seams must be overlapped in the same direction.
10. Close hole spacing is used at the top of all top sidewall sheets and at the bottom of all bottom
sidewall sheets.
Selecting the Proper Site
The selected site should be level, firm and free from underlying debris. The tank can be installed
satisfactorily on slopes, but as the slope increases, additional labor and materials are required for the
foundation. The concrete foundation surfaces must be level. If some fill is required, it should be watered
and tamped thoroughly to prevent uneven settling from the weight of the tank. Good water drainage
should be provided to prevent water collecting under or around the tank. Naturally, the site must allow
convenient access for easy loading and unloading, plus provide additional space for future units. Also,
consider the positioning of handling equipment, availability of electricity, etc.
