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.
5. 2.66" Corrugated Commercial Hopper Tank 4-9 Rings
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

5. 2.66" Corrugated Commercial Hopper Tank 4-9 Rings
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.).

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.

NCHT Ladder, Safety Cage and Platform Instructions 10-22 Rings
All grain bin packages, from 10 ring to 22 ring and 12' to 36' diameter, contain the correct components for assembly. 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. Read and follow the complete instructions for correct placement of parts. 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 equipment and other 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 parts and also to assure the correlation between the platforms is correct 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. 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 6C for the proper location of the two (2) 3/8" field drilled holes required to install the starter brackets.
Figure 6C
6. 2.66" Corrugated Commercial Hopper Tank 10-22 Rings
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 6D. 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. It will be necessary to field drill a 3/8" hole in the ladder section for the starter bracket as well. (See Figure 6F on Page 44.) See F igure 4B on Page 13 for the proper installation of additional ladder sections required. Standoff brackets must be installed on the ladder sections and attached to the sidewall at each horizontal seam and repeated every 32". Use 5/16" x 3/4" bin bolts for all connections.

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 tubes. (See Figure 6G.) 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 prevent the adjustable braces from slipping. (See Figure 6H.)
