Figure 7-24 Recommended lifting points for a Double A-frame section
A Purlin clip
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.
• Use evenly distributed connection points of support when lifting.
