Once you determine the platform location, position the platform wall
bracket 2” from the horizontal seam
bolt where the stairs will begin. Field
drill the bolt hole on the horizontal
seam and 4-5 more from top to bottom on the wall bracket and secure.
Use 5/16” x 1 1/4” bolt to attach wall
bracket.

When attaching the sidewall access platform to the
tank wall, vertical wall brackets need to be mounted
to the bin wall with 5/16” x 3/4” bin bolts (see Fig.
3). To insure the proper placement of the second
wall bracket, preassemble platform support (see Fig.
4) and mark the hole positions for drilling. Field drill
and assemble the platform support with 5/16” truss
head bolts. Now , proceed to the platform floor and
floor splice. Align holes on platform floor with the
holes on platform supports and bolt together using
5/16” x 3/4” truss head bolts and nuts. Be sure and
attach platform toe plate at the same time you attach
the platform floor (see Fig.6).

I. The stair wall bracket (LDR-4082) should be
placed on a horizontal seam and bolted vertically .
The vertical location must be field drilled to match
up with platform location. Use 5/16” x 1 1/4”
bolt to secure LDR-4082 to the sidewall. Field
drill 3 more holes and attach the bracket.
II. Using the two end holes of horizontal step bracket
attach it to LDR-4082 with (2) 3/8” x 1”flanged
head bolts and nuts.
III. Using the same bolts and nuts as step II connect
the knee brace (LDR-4084) to LDR-4083 and
LDR-4082.
IV . Continue to raise bin adding sidewall sheets until
the top hole of the next sidewall bracket can be
attached to a horizontal seam. Each step will
cover 9 3/8” on the horizontal seam. Two steps
will be added before the next brace assembly can
be mounted. There should be a distance of 18 3/
4” along the horizontal seam between brackets.
Fasten the lower end of the bracket to the seam
with a seam bolt. You will need to field drill
extra holes (2) as needed to finish fastening
the bracket to the seam. (Use 5/16” x 1 1/4”
Bin Bolts).
V. Complete the second wall support assembly as
previously instructed in step II and III

Step Preassembly
Figure 7: Step Assembly
LDR-4079 -- Step
LDR-4080 -- Right End
LDR-4081 -- Left End
Preassemble ends to step with 5/16” truss head bolts.
Put all bolts in the bottom of the step and install the
bottom two bolts on the back of the step and tighten.
Step to Horizontal Bar Attachment
Attach step assembly to the top horizontal bracket
with two 5/16” x 3/4” T russ head bolts. Use the outer
set of holes in the horizontal bracket. Attach another
step to the lower horizontal bracket. Maneuver the
next step in between the others and attach the top
side tabs to the outside of the upper steps with truss
head bolts see Figure 8. Attach lower step tabs in
the same manner.
Tie Strap Attachment
Attach the steps to each other with the tie straps (LDR-
4090). Use 5/16 x 3/4” truss head bolts and nuts to
attach the strap to the holes provided on the ends of
the step. Align the step slots and level the steps before tightening. The steps will align to curvature and
wall brackets. When all the parts of the top section
are in place tighten all the bolts.

The handrail post (LDR-4085) connects
to the end of the horizontal wall bracket
with (2) 3/8” x 1” Flange head bolts and
nuts. Tighten the bolts and move on to the
next section. The handrail will be installed
after all stair sections are on the tank. (See
figure 10 on page 7 for a detailed drawing
of the first few steps and the hand railing.)

Cut out notches to fit
around handrail posts.
Platform to Step Splice
Platform Splice
TDP-5010
Use platform splice (TDP-5010) to cover
the gap between the platform and the stair
section. Since the gap changes with bin
diameter, field drilling and cutting are required for proper placement of the splice.
The attachment tabs on the top of the step
may need to be trimmed to allow fit (refer
to figure 9 on page 7). The splice will also
need to be notched to fit around the handrail post. Secure to the step and platform
with truss head bolts and nuts.

Continue raising the bin until the next wall
bracket can be attached to the wall 3
spaces (2.66” Corrugation) or 4 spaces
(4.00” Corrugation) along the horizontal
seam. Bolt the rest of the assembly in place
and field drill to secure. Place a step over
the wall bracket and secure. Hang the three
steps between brackets to finish the section. Align steps level with tie straps and
tighten section. Add the handrail post and
continue adding sections.

The bottom wall bracket will need to be
field drilled in order to attach the last horizontal bracket. The top of the horizontal
bracket should be a distance of 11” up
from the base of the tank. Attach the bottom step as previously directed. The front
lip of the bottom step may need to be
trimmed off to allow fitup. Add the two
other steps, level and tighten all bolts and
tie straps. Install the bottom handrail post.

top post location. T rim off the narrow end
and drill for top connection. Connect with
5/16” x 1 1/4” bolt and nut. Slide the next
narrow end into the upper wide end of the
next rail. Align the slots and attach to post

Continue down the stairs installing handrail sections. Extra force maybe needed
to curve the handrail for attachment to the
post. W ith smaller diameter tanks the bottom section of the handrail will require a
field drilled hole for the attachment to the
last post.

After installing top handrail bolt the intermediate handrail in place. The handrail
section consists of a large tube and a small
telescoping tube. The large tube is located
on top. Bolt the rail in place with a 5/16”
x 1 1/4” bin bolt and nut. Continue up the
steps adding the handrail. The top middle
handrail section will need to be shortened
to fit and to complete the installation.
