Guidelines for Assembling and Lifting the A-Frame Rafter Sections
The roof is assembled in sections and referred to as A-frame sections. Each A-frame section is
assembled on the ground and lifted into place.
IMPORTANT:
Do not drill additional holes in purlins. Install the flange bolts and nuts based on the
number of holes in the purlins.
NOTE:
Use purlin clips as lifting references as shown.

The A-frame section has two configurations: with diagonal bracing and without. The number of A-frame
sections with diagonal bracing depends on which size bin is being constructed.
