Installing the Roof Ladder Steps
Roof ladder steps will allow access to the manway access and peak.
What You Should Know
Each eave-to-peak ladder step differs with the diameter of each bin. When installing the ladder steps,
always start from the eave and work up towards the peak, installing the longer steps first at the eave and
the shorter steps later at the peak.
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
.
1. Place the first roof ladder step (15) onto the corresponding roof panel (44), next to the manway
access.
NOTE:
Roof ladder steps (15) will not be installed at places where roof rings will be installed.
Proceed to next available ladder step.
2. Place a 5/16" sealing washer (8) between the roof ladder step (15) and the roof panel rib. Secure
the roof ladder step (15) to the roof panel rib by installing 5/16" x 1" flange bolts (1) and 5/16" flange
nuts (10). Tighten all the hardware to the recommended torque specifications. See
.
3. Repeat this procedure for the remaining ladder steps (15) in the eave-to-peak ladder step.
