Lifting Points
To determine the required lifting cable lengths and whether
four-or six-point lifting is required, use Table 5 & Table 6 and
Figure 25 & Figure 26.
Referring to Figure 25 & Figure 26, note that dimension A is
the distance between the outer lifting points. The four outer
rigging cables must be equal to or longer than dimension A.
Dimension B shows the minimum distance between the outer
and the inner lifting points for six-point lifting. This can be
used to roughly determine the required length of the middle
cables for six-point lifting. Dimension A can be determined by
subtracting dimensions X and Y from dimension Z.
(i.e., A = Z- X-Y).
Where:
Z =Total unit length in inches
(refer to certified drawings for this dimension).
X =Outdoor/return air section length
(refer to Table 5 for this dimension).
Y = Refer to Table 6 for this dimension
(see Figure 25 & Figure 26).
If A ≤ 288" (7315 mm), 4-point lifting is sufficient.
If A > 288" (7315 mm), 6-point lifting is required.
