NOTE: A-frames labeled “A1” through “A5” have X-bracing and are installed first. A-frames labeled “A6”

through “A12” 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 75 ft diameter bins

Length from the center collar 216.1 in. (548.89 cm)

Length from 11.6 ft diameter location 148.5 in. (377.19 cm)

Length from 26.3 ft diameter location 56.6 in. (143.76 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.
