3. Safety Decals
The manufacturer does not warrant any roof damage caused by excess ive v acuum or internal
pressure from fans or other air moving systems. Adequate ventilation and/or “makeup air”
devices should be provided for all powered air handling systems. The manufacturer does not
recommend the use of downward flow systems (suction). Severe roof damage can result from
any blockage of air passages. Running fans durin g high humidity/cold weather conditions can
cause air exhaust or intake ports to freeze.
Roof Damage Warning and Disclaimer
CAUTION!
Excessive vacuum (or pressure) may
damage roof. Use positive aeration
system. Make sure all roof vents are
open and unobstructed. Start roof
fans when supply fans are started.
Do not operate when conditions exist
that may cause roof vent icing.

4. General Detail Information
Extension Rail Installation
All ladder systems that include a safety cage must also include ladder extension rails attached to the top
four foot (4') ladder section. Start by bolting the spacer brackets through the top and bottom set of holes
in the top ladder section. Then, attach the extension rails to the spacer brackets as shown in Figure 4A.
When installed correctly, the bottom of the extension rail should be flush with the bottom of the top ladder
section. Use 5/16" x 3/4" bin bolts for all connections.
Figure 4A Ladder Extension
12PNEG-1451 Ladder, Safety Cage and Platform for Hopper Tanks
4. General Detail Information
Wind rings must be installed in relation to the ladder rungs as
shown here, to insure compliance with O.S.H.A. regulations.
Ladder Section Assembly
Two (2) splice plates (LDR-4317) are required to attach each ladder section. The head of the bolt
should be to the inside of the ladder with the splice plate on the outside as shown in Figure 4B.
Use 5/16" x 3/4" bolts for all connections.
NOTE: With most installations, the last ladder section installed to reach the ground, the base or the
intermediate platform should be cut to fit.

NCHT Ladder, Safety Cage and Platform Instructions 4-9 Rings
All grain bin packages, from 4 ring to 9 ring and 12' to 35' diameter, contain the correct components for
assembly. Read and follow the complete instructions for correct placement of parts. Be sure and use the
charts to determine the appropriate number and size parts to be used based upon the number of rings in
the bin. Failure to do so may result in an improper fit or shortage of parts. Pay particular attention to the
location of ladders and platforms as they relate to the other equipment and structures in the area.
Eave Starter Bracket Installation
Correct placement of the eave ladder starter bracket is critical to assure proper fit of all ladder co mponents
and to assure the correlation is correct between the platforms for proper installation of the access door
platform. If the eave starter brackets are mislocated, standard installation of the access door platform will
not be possible.

Location of Field Drilled Holes for Eave Ladder Starter Brackets
The starter brackets must be located directly below the roof ladder. Before the starter brackets can be
installed, two (2) 3/8" holes must be field drilled 2.66" below and directly in line with the top row of
pre-punched horizontal holes. The first hole, required for the left hand starter bracket, must be located
9-3/8" from the center of the stiffener to the center of the hole as shown in Figure 5B. The second
hole, required for the right hand bracket, must be located 18-3/4" from the center of the first hole. Refer to
Figure 5B for the proper location of the two (2) 3/8" field drilled holes required to install the starter brackets.
Figure 5B

Eave Starter Bracket and Ladder Assembly with Safety Cage
Once the two (2) 3/8" holes have been field drilled, attach the starter brackets to the sidewall as shown in
Figure 5C. Check the top ladder section to make sure the ladder rung dimples are to the top. Attach starter
brackets to the top of the ladder. See Figure 4B on Page 13 for the pro per installation of addit ional ladder
sections required. Standoff brackets must be installed on the ladder sections an d attached to the sidewall
at each horizontal seam and repeated every 32". Use 5/16" x 3/4" bin bolts for all connections. It is also
necessary to field drill a 3/8" hole on the ladder section for each starter bracket (L.H. and R.H.).

NOTE: Refer to general detail information on Page 12 for additional d etails for sta ndoff bracket to ladde r
assembly and also, 8' extension rail installation (omitted in detailed figure above for clarity).

Eave Adjustable Braces
The eave adjustable braces must be attached at this time. An eave adjustable brace is comprised of
one large diameter tube and two (2) smaller diameter tubes. (See Figure 5F.) Slide the smaller tubes
inside the larger tubes and attach one smaller tube to the top of the ladder extension rail. Adjust the other
smaller tube so the bottom of the flattened tube reaches the roof panel. Field drill four (4) 5/16" holes
through both large and small tubes and bolt together using 1/4" x 1-1/2" bolts and nuts. This will prevent
the adjustable braces from slipping. (See Figure 5G.)
NOTE: Refer to Page 24 for proper location of ladder starter brackets.

Eave Platform Mounting Angle Installation
Figure 5H shows the location of the platform mounting angles. Each angle must be mounted starting
4" below the top horizontal seam of the second ring with the first mounting angle offset 9-3/8" from the
right hand starter bracket. The second mounting angle must be located 56-1/4" from the first mounting
angle. The dimensions and locations of these angles are critical for proper fit of all parts. Using the platform
mounting angels as guides, field drill 3/8" holes in the sidewall every 8". (See Figure 5H.)

Right Hand Platform and Platform Support Assembly
NOTE:
Assemble the platform support frame using 5/16" x 3/4" truss head bolts and nuts. (See Figure 5I.) Wh en
attaching the platform mounting angles to the sidewall, locate the mounting angles according to the
instructions on previous pages. Align holes on the platform floor with the holes on the platform supports
and bolt together using 5/16" x 3/4" truss head bolts and nuts. Attach platform toe plates at the same time
as attaching the platform floor. The vertical entrance angle bolts to the platform floor, toe plate and
platform support. The handrail post bolts to the platform floor and toe plate as shown in Figure 5J.
Mount the platform supports on the bin first. Next, assemble the platform floor onto the support
frame. Do not tighten platform support to floor brace bolts until the floor and toe plates are secure.

(See extension angle hole detail
on Page 15 for proper installation.)
Eave Safety Cage Hoop Assembly
Before attaching any pieces to the ladders or platform, some pre-assembly is required. Attach two (2)
safety cage brackets to the 8' extension rail and one safety cage bracket to the second 4' ladder section
as shown in Figure 5K. Bolt the safety cage hoop adjuster plates onto the extension angle as shown in
Figure 5K. Using the proper configuration depending on the bin diameter (see adapter assembly detail
on Page 30), bolt the safety cage hoop adapters together and attach to the safety cage hoop halves.
Be sure to use the 5/16" x 3/4" bolt with the head of the bolt to the inside of the safety cage. Bolt these
assemblies to the safety cage brackets and hoop adjuster plates (See connection detail on Page 30 for
proper hole location). Tighten bolts as you go. The bottom asse mbly requires two (2) hoop halves and will
be positioned just below the platform as shown in Figure 5K. Use the safety cage hoop adjuster angle to
secure the two (2) hoop half assemblies to the vertical entrance angle on the platform assembly.
NOTE: 48" Vertical supports removed in Figure 5K for clarity.
