PNEG-1085 72'-90' Externally Stiffened 2 Ring Door
Written instructions for installation of a NCWT0084 (72'-90' diameter bin/silo) 2 ring door package
in a externally stiffened tank (Continued).
The horizontal seam of the sidewall sheet above the door header will bolt to the jamb plate where it
extends above the door frame. The sidewall will be on the exterior of the plate. Install base angle
(B-6753) at the area the plate does not extend above. Utilize silicon caulk as necessary to seal
this location.
Standard base stiffeners will mount directly above the external door frame stiffener. Shim as
necessary for firm support and bolt the stiffeners together using a 3/4" x 5" bolt, 3/4" nut and
3/4" washers.
7. Bearing pins, WD-6224 (8), are mounted to the inside frame flange at the 8 large/0.65" x 0.75" slots.
Use S-2741, 5/16" x 1-1/2" bin bolts 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" washer
(S-845) and 5/16" flange 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
. 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 when 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. Center the bearing pins in the door panel holes and tighten.
Then attach the door panel hinges to the frame hinges. Adjust the door panels until they open and
close smoothly.
9. Attach the outer cover angles (NCWT0168) to the outer frame weldment with 5/16" x 1-1/4" bolts.
Use a 5/16" flat washer for all connections. Refer to
10. Attach the latch plates (NCWT0166) and outer cover hinge weldments (NCWT0165) to the outer
cover angles as shown on
. Use 5/16" x 1-1/4" bolts for all connections. Remove the sealing
washer from the 5/16" bolt and replace it with a flat washer. The sealing washer will be used under
the nut on the outside of the latch plates and hinge weldments.
11. Assemble the outer as shown in
. Attach the door reinforcement channels (NCWT0162),
retaining brackets (WD-033) and the outer cover hinges (NCWT0170) to the outer cover as shown.
Use 5/16" x 3/4" bolts for all reinforcement channel connections and 5/16" x 1-1/4" bolts for all hinge
and retaining bracket connections. The bolt head and sealing washer should be on the outside for
these connections. An additional sealing washer may be placed between the hinge/retaining bracket
and the outer cover. Adjust the hinge until the door opens and closes smoothly. 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 damaged or missing, please contact GSI
for replacement.
12. Caulk as necessary at the top and bottom juncture of the door frame and the sidewall and foundation.
