Rigging Manual

RS-1B Structural-Strength Ratings:

The working-load limit of each individual rigging point on the rear of an X-Line enclosure is

dependent upon the rigging-track/bracket assembly as it is mounted in the enclosure and the RS-

1B swivel-ring double-stud fitting. The Xvls, Xvlt, Xsub, Xfil1 and Xfil2 enclosures have identical

rigging track at the rear of the enclosure and have the same structural-strength ratings when used

with the RS-1B, as shown in Figure 19a. It should be noted that the structural ratings are the

same with any angle of pull. There are two rigging points at the rear of the enclosures. The

structural ratings shown in Figure 19a are for a single rigging attachment point. Each rigging point

has the same rating.

The working-load limit of each individual rigging point on the front of an X-Line enclosure is

dependent upon the rigging-track/bracket assembly as it is mounted in the enclosure and the RS-

1B swivel-ring double-stud fitting. The Xvls, Xvlt and Xsub enclosures have identical rigging track

at the front of the enclosure and have the same structural-strength ratings when used with the

RS-1B, as shown in Figure 19b. It should be noted that the front-to-back angle range shown in

Figure 19b is only 270° for the RS-1B because the fitting can only be put into tension and the

enclosure prevents a full 360° rotation. It also should be noted that, with these enclosures, the

RS-1B fittings are only rated for use over side-to-side pull angles of a maximum of ±5°, as shown

in Figure 19b. There are two rigging points at the front of the enclosures. The structural ratings

shown in Figure 19b are for a single rigging attachment point. Each rigging point has the same

rating.

The Xfil1 and Xfil2 have their front rigging track hardware located on the sides of the enclosure,

and have the same structural rating when used with the RS-1B, as shown in Figure 19c. It should

be noted that the structural ratings for the Xfil1 and Xfil2 enclosures are the same with any angle

of pull. There are two rigging points at the front of the enclosures. The structural ratings shown in

Figure 19c are for a single rigging attachment point. Each rigging point has the same rating.

CAUTIONS for a Complex Structural Rating Analysis:

WHEN APPLYING A COMPLEX STRUCTURAL RATING ANALYSIS TO ANY

X-LINE LOUDSPEAKER SYSTEM SUSPENDED OVERHEAD, THE USER MUST

OBEY THE FOLLOWING RULES:

1. For the front of every enclosure in an array, never exceed the working-load-versus-angle

limit for the Xvsg, Xvsl, Xvsd and Xvsf rigging assemblies. Never exceed the side-to-side

angle limits.

2. For the back of every enclosure in an array, never exceed the working-load-versus-angle

limit for the Xvhl linking hinges, Xvhg grid hinges, Xvhp pick-up hinges or Xvbp pull-up bar.

Never exceed the side-to-side angle limits.

3. Always make sure that the rear hinge locking pins on every Xvhl linking hinge, Xvhg grid

hinge, Xvhp pick-up hinge and Xvbp pull-up bar are fully engaged in the rigging track on

the back of every enclosure (and grid, when applicable) before lifting overhead.

4. Always make sure that the locking pins on all the front triple-stud fittings on every front

Xvsg, Xvsl Xvsd and Xvsf rigging assembly are fully seated and locked in the rigging track

base on the front of every enclosure (and grid, when applicable). Always make sure that

there is not a twist in these chains before lifting overhead.
