6.31 Working Load Limits for Eyebolts
Eyebolts can be used to suspend individual loudspeakers and certain types of clusters. Eyebolts attach
to the EVF and EVH enclosures through the integral M10-1.5 attachment points. Section 5.21 Anatomy
of an EVF or EVH Flying System Using M10 Eyebolts should be reviewed at this time for more information
on eyebolt alignment and positioning on the enclosure. Table 9 shows the WLL per eyebolt with respect
to the angle of the applied load. Figure 25 shows the suspension-point angles that are referenced in the
table. It is a good idea to stay within 30° of the maximum WLL of the eyebolt (straight up position) for
main suspension lines.
