Mechanical Installation:
Rigging and Handling
Lifting Points
To determine the required lifting cable lengths and whether
four-or six-point lifting is required, use Tables 8 and 9 and
Figures 33 and 34.
Referring to Figure 33 and Figure 34, 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. Use this to
roughly determine the required length of the middle cables for
six-point lifting. Determine dimension A by subtracting
dimensions X and Y from dimension Z (e.g., 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 8for this
dimension).
Y = Refer to Table 9 for this dimension (see Figure 33 and
Figure 34).If A
≤
288" (7315 mm), 4-point lifting is sufficient.
If A > 288" (7315 mm), 6-point lifting is required.
