ELECTRO-VOICE ® 2 Rigging-Safety Warning This document details general rigging practices appropriate to the entertainment industry, as they would apply to the rigging of Electro-Voice X-Line loudspeaker systems.
ELECTRO-VOICE ® 3 0. Introduction The X-Line loudspeaker systems represent an important step in line-array technology for large- scale sound reinforcement.
ELECTRO-VOICE ® 4 1. X-Line Rigging System 1.1 Overview of the X-Line Flying System The X-Line loudspeaker systems have been designed to construct acoustic line arrays. Acoustic line arrays typically consist of independent columns of loudspeaker systems.

ELECTRO-VOICE ® 6 The grid is suspended by two hoist motors that are attached to two pickup points on the top of the grid one at the front and one at the back. The two grid pickup points are in line and are adjustable front to back to help distribute the loads between the hoist motors.

ELECTRO-VOICE ® 10 The Xfil1 and Xfil2 enclosures use a slightly different rigging track arrangement at the front. In this case, another pair of proprietary high-strength, extruded aluminum-alloy track/bracket assemblies are mounted on the sides of the enclosure near the front, as shown in Figure 3d.
ELECTRO-VOICE ® 11 Figure 4: External Rigging Hardware Details Figure 5: Rear Rigging Hardware Installation Details Xvhl Linking Hinge Xvhg Grid Hinges, Xvhp Pickup Hinges, or Xvbp Pull-Up Bar CAUTION Hinge Locking Pins Must be Fully Engaged In Track Before Lifting Overhead 16.
ELECTRO-VOICE ® To remove the Xvhg grid hinge, grasp the locking-pin knob and pull out while applying pressure on the hinge to slide the hinge base toward the long cutout at the end of the track. The hinge base will come out of the track once it is aligned with the cutout.
ELECTRO-VOICE ® 13 The grid hinges must be installed with the hinge bases located at the outside of the track towards the sides of the enclosure as shown in Figure 5 with the locking pins on the fittings located next to the sides of the enclosure.
ELECTRO-VOICE ® 14 ALWAYS CHECK TO MAKE SURE THAT THE GRID STRAP FITTING IS SECURELY LOCKED INTO THE TRACK, THAT THE LOCKING PIN IS FULLY SEATED INTO THE BASE OF THE TRACK AND THAT THERE IS NO TWIST IN THE CHAIN BEFORE LIFTING ANY LOUDSPEAKER ENCLOSURE OVERHEAD.
ELECTRO-VOICE ® 15 ALWAYS CHECK TO MAKE SURE THAT THE LINKING STRAP FITTING IS SECURELY LOCKED INTO THE TRACK, THAT THE LOCKING PIN IS FULLY SEATED INTO THE BASE OF THE TRACK AND THAT THERE IS NO TWIST IN THE CHAIN BEFORE LIFTING ANY LOUDSPEAKER ENCLOSURE OVERHEAD.
ELECTRO-VOICE ® 16 Xvsf Rigging Fitting: Two Xvsf rigging fittings can be used to attach the front of an X-Line enclosure directly to a building structure or to a grid assembly that is not compatible with the X-Line rigging track. The fitting is a proprietary triple-stud fitting that has a large steel locating plunger.
ELECTRO-VOICE ® ALWAYS CHECK TO MAKE SURE THAT THE PULL-UP-BAR HINGE BASES ARE INSTALLED WITH THE CORRECT ORIENTATION WITH THE HINGES AT THE OUTSIDE EDGES OF THE TRACK.
ELECTRO-VOICE ® The grid also has rigging track on the middle crossbar that runs side to side that matches the track on the rear of the enclosures. Either the Electro-Voice Xvhg grid hinge or the Xvhl linking hinge may be used to attach the rear of the top box to the grid.
ELECTRO-VOICE ® 2. X-Line Rigging and Flying Techniques 2.1 Array Considerations The X-Line loudspeaker systems have been specifically designed to construct acoustic line- arrays. Line-array systems typically consist of independent columns of loudspeaker systems.
ELECTRO-VOICE ® The rigging straps are shipped from the factory with chain connected in the A position on the fittings on both ends. (This would be denoted as an A-A length.) When the chain is connected in the B position on both fittings (known as the B-B length), the strap is 0.
ELECTRO-VOICE ® In this document and in the software modeling program, the front rigging fitting attachment locations are denoted by the number of holes showing in the rigging track once a rigging strap is installed.
ELECTRO-VOICE ® 2.4 Rigging an Array with Boxes Using X-Line Dollies Three dollies are available for transporting the X-Line loudspeaker systems. The actual array rigging technique will vary depending on which dollies are used to transport the systems.
ELECTRO-VOICE ® Figure 9: Flying with Stacking Dollies 23 Step 4: Land the suspended array on top of the next stack. Attach the rear hinges between the two stacks. Attach rigging chain at the front between the two stacks to achive the desired vertical angles.
ELECTRO-VOICE ® Figure 10: Flying with Front Dollies The two boxes must be held parallel during the installation of the rigging hinge. If there is a slight vertical misalignment that causes the hinge to bind during installation, either the suspended box or the box on the dolly may be manually lifted to facilitate the hinge installation.
ELECTRO-VOICE ® Once again, the array is lifted until the box on the Front Dolly is no longer contacting the ground and the dolly is removed from the box. At this point, the next to last box is manually lifted and the front Xvsl linking straps are attached between the box next to the bottom and the box above it.
ELECTRO-VOICE ® 3. Rigging-Strength Ratings, Safety Factors, and Special Safety Considerations 3.1 Working-Load Limit and Safety Factor Definitions: The structural ratings for all of the X-Line rigging components and complete loudspeaker systems are based on test results in which parts were stressed to failure.
ELECTRO-VOICE ® The array designer must be aware of the working-load limit ratings and the loads being applied to the individual rigging points and the overall enclosure. An X-Line loudspeaker system is only as strong as its weakest link. It is usually the case that one of the working-load limits will be approached sooner than the other.
ELECTRO-VOICE ® Figure 11: Simplified Rating Guidelines Figure 11 includes a graph of the working-load weight-versus-angle limit rating for the X-Line enclosures.
ELECTRO-VOICE ® In addition, the guidelines in Figure 11 include a side-to-side angle limit for the Xvhg grid hinges and the Xvhp pickup hinges. Side-to-side angle limits are not necessary for the Xvhl linking hinges because side-to-side angles are impossible to achieve if the top rigging is within its limits.
ELECTRO-VOICE ® 3.4 Complex Structural-Rating Analysis For a complete structural-rating analysis, the forces in each individual piece of rigging hardware throughout the X-Line system must be determined, as well as the forces on each enclosure. Determining these forces requires complex mathematical calculations.

ELECTRO-VOICE ® 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.

ELECTRO-VOICE ® CAUTIONS for a Complex Structural Rating Analysis (continued): 5. Only use Xvhl linking hinges, Xvhg grid hinges, or Xrhp pickup hinges manufactured by Electro-Voice. 6. Only use Xvsg, Xvsl, Xvsd or Xvsf front rigging assemblies manufactured by Electro-Voice.
ELECTRO-VOICE ® 4. Rigging Inspection and Precautions Electro-Voice X-Line Loudspeaker Systems: Prior to each use, inspect the loudspeaker enclosures for any cracks, deformations, missing or damaged components that could reduce enclosure strength.
ELECTRO-VOICE ® Building, Tower or Scaffold Supports: Prior to each use, the strength and load-bearing capabilities of the building, tower or scaffold structural supports should be evaluated and cert.
