40 Series Roof Ladder
Step Installation
Installing Roof Ladder Steps
Roof ladder steps will allow access to roof and manway access.
What You Should Know
Each eave-to-peak ladder step package (E) will differ with the diameter of each bin. When installing the
ladder steps, always start from the eave and work up toward the peak, installing the longest step first and
the shortest step last.
NOTE: Use the table at the end of this procedure for part listings and the correct placement of each ladder
step configuration for various bin sizes. See eave-to-peak ladder step kit, ladder step placement
on Page 3 .
1. Place the first roof ladder step (B) onto the corresponding roof panel, next to the manway access (G).
NOTE: If support rings will be installed, roof ladder steps (B and F) will not be installed. Proceed to
next available ladder step.
2. Install two (2) flange bolts (A) and install two (2) sealing washers (D) between the ladder step (B)
and the roof panel rib. Secure the roof ladder step to the roof panel with two (2) flange nuts (C).
Tighten to the recommended torque specifications, see bolt torque specifications.
3. Repeat this procedure for the remaining ladder steps in the eave-to-peak ladder step package (E).
