NOTE: A-frames labeled “A1” through “A4” have X-bracing and are installed first. A-frames labeled “A5”
through “A10” are standard A-frames. The empty spaces that are not labeled must have purlins
installed between the rafters after all the A-frames are secured. The numbers reflect the recom-
mended installation sequence of the A-frame assemblies.
Table 7-2 Starting lengths for temperature cables for 60 ft diameter bins
Length from the center collar 179.80 in. (434.06 cm)
Length from 20 ft diameter location 58.1 in. (147.57 cm)
The temperature cable lengths in the chart above are the distances from where the temperature cable
attaches to the rafter or the center collar to the top ring. To calculate the correct temperature cable length,
add 32 inches for each bin ring to the starting length. Temperature cables must terminate above any
unload equipment and be secured in place with twine. DO NOT allow cables to become tangled in unload
equipment.
