2.4 Rigging an Array with Boxes Using X-Line Dollies
Three dollies are available for transporting the
The Bottom Stacking Dolly can be used with the rectangular loudspeaker enclosures (Xvls, Xsub). Up to four loudspeaker systems can be stacked on top of a single dolly. The enclosures all sit upright as they would be arrayed. These dollies have sufficient clearance to allow the enclosures to travel with both the front and rear rigging hardware attached to the loudspeaker systems. This makes rigging set up and tear down extremely easy because the loudspeaker enclosures can be moved in blocks of four units. The Downfill Stacking Dolly can be used with one downfill enclosure (either the Xfil1 or Xfil2) and two Xvlt systems. The three loudspeaker systems are stacked so that the enclosures all sit upright as they would be arrayed. The dollies are designed to accommodate the slanted baffle of the Xfil1 and Xfil2 and the trapezoidal shell of the Xvlt systems. These dollies have sufficient clearance to allow the enclosures to travel with both the front and rear rigging hardware attached to the loudspeaker systems. Like the Bottom Stacking Dollies, this makes rigging set up and tear down extremely easy because the loudspeaker enclosures can be moved in blocks of three units.
The Front Dolly can be used with either the rectangular enclosures (Xvls or Xsub) or trapezoidal enclosures (Xvlt). The front dolly attaches to the front of a single loudspeaker system covering the grille and the enclosure front rigging track. This dolly allows the ease of moving one loudspeaker enclosure at a time; however, the rigging cannot remain attached to the enclosure during transport.
Because most arrays typically require more rectangular Xvls and Xsub systems than trapezoidal Xvlt systems, it would be common in a
Figure 9 illustrates the technique used to construct a loudspeaker array with enclosures transported on Bottom Stacking Dollies. First, a stack of enclosures on a Bottom Stacking Dolly is rolled underneath the grid. The grid is lowered and the top box is attached to the grid. The Xvsg and Xvsl chain rigging straps are attached at the front to achieve the desired vertical angles. The four boxes are lifted high enough that another column of loudspeakers on a stacking dolly can be rolled in under the suspended array. The array is then landed on top of the next stack of loudspeakers and rigging hardware is attached between the flown stack and the stack on the dolly. The entire column of loudspeakers is then lifted overhead. The process is repeated as necessary to add more loudspeakers to the column. The process is identical for both the Bottom Stacking Dolly and the Downfill Stacking Dolly.
Figure 10 illustrates the technique used to construct a loudspeaker array with enclosures transported on Front Dollies. The figure starts out showing four enclosures suspended overhead. The array is lowered and a single enclosure on a front dolly is rolled into position behind the flown array. The array is lowered until the bottom corner of the bottom box of the array lines up with the rear corner of the box facing the ground on a Front Dolly. The Xvhl rear linking hinge is then simultaneously installed in the rigging on the suspended box and the box on the dolly.
