5.213 All-Eyebolt Clusters

A basic two-cabinet flying system is shown in Figures 19 and 20, illustrating the components necessary to make a typical two-system horizontal or vertical cluster using M10 eyebolts. Secure cabinets to the building structure with user-supplied hardware. All user-supplied hardware, shackles, wire rope, bolt con- nectors, etc., must be rated for overhead lifting. Refer to section 1 for suspension point locations.

A second enclosure may be suspended from the first by using the same M10 rigging points on the second enclosure. Connection between the two enclosures through the M10 eyebolts requires hardware sup- plied by the end user. All user-supplied hardware must be rated for overhead lifting. The angle between the two enclosures as well as the angle between the first enclosure and the structure can be controlled by the length of the user-supplied hardware. If the desired angle cannot be achieved by varying the length of this hardware, then pull-back points can be used. It is recommended that both the top and the second box use a pull back. The pull back can be achieved with the use of additional M10 eyebolts at the back of the enclosures. The hardware used to achieve the pull back is supplied by the end user.

A maximum of two enclosures is allowed with all-eyebolt clusters.

A minimum of two eyebolts are required for suspension of all-eyebolt clusters.
