Ring
Written instructions for installation of a NCWT0435 (105' diameter bin/silo) 2 ring door package in
the 2
nd
and 3
rd
rings of an externally stiffened tank. (Continued)
The horizontal seam of the sidewall sheet above and below the door frame will bolt to the jamb plate
where it extends above and below the door frame. The sidewall will be on the exterior of the plate.
Install top/bottom seal angle (NCWT0239) at the area the plate does not extend above and below
the door. Bolt the seal angle to the sidewall horizontal seam and utilize silicon caulk as needed to
seal this location.
The exterior door frame will mount directly above the stiffener supports. Special base stiffeners will
mount directly above the frame stiffener. Shim as necessary for firm support and bolt the stiffeners
together using a 1" x 4-1/2" bolt, 1" nut and 1" washer.
7. Bearing pins, WD-6224 eight (8), are mounted to the inside frame flange at the eight (8)
large/0.65" x 0.750" slots. Use 5/16" x 1-1/2" bin bolts (S-2741) and attach the pin to these
eight (8) locations by inserting the grooved pin into the hole and running the 5/16" bolt to the inside.
Use 5/16" flat washer (S-845) and 5/16" flanged head nut (S-3611) to secure
bearing pin.
8. Assemble the door handle reinforcement angles, door handles, latches and hinges to the top and
bottom inner door panels as shown in the assembly sketches.
Install the
1/2" x 1-1/2" bolts in the outer door frame at four (4) locations and thread the door latch bar holder
(WD-6234) onto the bolt. The door handle will mount over these holders then installed. Utilize
washers if necessary to adjust the latch bar holder position.
Mount the door panel
onto the four (4) bearing pins and lock the latches over the latch bar holder. Then attach the door
panel hinges to the frame hinges. Adjust hinges and latch bar holders until door panels swing freely
and the latch bars lock over the holder completely. Apply 1" x 1/2" foam seal strip to inner frame
weldment to seal inner door panels.
9. Attach the outer cover angles (NCWT0174) to the outer frame weldment with 5/16" x 1-1/4" bin bolts
(S-277). Remove the sealing washer from the bolt and replace it with a flat washer. Use a flat washer
on all slotted connections. Bolt heads should be on the outside for these connections.
10. Attach the outer cover hinge weldments (NCWT0165) and latch plates (NCWT0166) to the outer
cover angles as shown on
. Use 5/16" x 1-1/4" bolts with flat washers on each side for all
connections. Bolt heads should be on the inside for all connections.
11. Assemble the exterior cover as shown in the assembly sketch.
Install the retaining
brackets (WD-033), outer cover hinges (NCWT0170) and reinforcement channels (NCWT0162) to
the outer cover as shown. Use 5/16" x 1-1/4" bolts for all hinge and latch bracket connections and
5/16" x 3/4" bolts for all reinforcement channel connections.
Bolt head with sealing
washer should be on the outside for all of these connections. An additional sealing washer should be
placed between the retaining bracket/outer cover hinge and exterior cover. Adjust the outer cover
hinges as necessary until door opens and closes smoothly. Apply sealant all around door frame at
outer cover location. Check to ensure that the unloading decals (DC-GBC-2A and DC-GBC-2S)
are installed on the outside of the outer door cover. Check to ensure that the danger decals
(DC-GBC-1A and DC-GBC-1S) are installed on the inside of the outer door cover. If decals are
missing or damaged contact GSI immediately.
12. Caulk as necessary at the top and bottom juncture of the door frame and the sidewall and foundation.
