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

The A-frame rafter section has two configurations: with X-bracing and without. The number of A-frame
rafter sections with X-bracing depends on which size bin is being constructed.
DANGER
All lifting should be performed by a certified crane operator with prior bin
construction experience. Never lift during windy conditions.
General Guidelines:
• Construct the A-frame sections on flat ground or blocking.
• Install the temperature cable brackets at the same time you assemble the A-frame sections.
• Always be aware of the orientation of each part prior to assembling.
• Use the correct hardware for the part being assembled. Never substitute hardware.
• Always ensure hardware is tightened prior to lifting.
• Always practice safety when assembling rafter sections. Be aware of others around you when
moving long A-frame sections.
