6.0 Rigging-Strength Ratings and Safety Factors (cont’)
6.4 VRK Rigging Structural Ratings for Vertical Clusters
The guidelines for simplified vertical structural ratings cover the following information:
1. Maximum length of the cluster.
2. Maximum weight of the cluster.
3. WLL for eyebolts.
4. Trim angle.
5. Tie points for eyebolts.
6. Left-to-right vertical cluster angles.
The majority of vertical clusters will be suspended using a combination of VRK vertical rigging kits and
factory-supplied eyebolts. For a vertical cluster, select the eyebolt position that results in the highest eye-
bolt strength as shown in Table 12. Different eyebolt positions are shown in Figure 28.
