[. . . ] The LAPS program can be used to determine which hole to use to achieve the desired vertical angle. The centering ring positions the pickup ring in the center of the CBEAM slot so that array will hang straight and not tilt sideways. To relocate the pickup ring, remove the cotter pin from the clevis pin and remove the clevis pin from the beam assembly. Move the pickup ring and centering ring to the desired hole and reinstall the clevis pin in the beam assembly holes, then secure the clevis pin with the cotter pin. For Shipping/Transport, the yoke and ring assemblies may be installed in the beam assembly, as shown in Figure 9e, so that all moving parts are recessed. MAKE SURE THAT THE EACH CLEVIS PIN SECURING EACH PICKUP RING TO THE BEAM IS LOCKED IN POSITION BY THE COTTER PIN. DO NOT LIFT ANY ASSEMBLY OVERHEAD WITHOUT A COTTER PIN TO LOCK EACH CLEVIS PIN.

This makes it possible to attach a grid to the bottom of an enclosure. The bottom grid can be used as a pull back on the bottom of a column to achieve downward tilt angles for the entire array that are greater than could be achieved from just a grid. The XLVC-BGK consists of two front hinge bars, two rear swing arms, a shoulder bolt for the hinge bars and four sets of quick-release pins with screws to attach the lanyards to the enclosure rigging, as shown in Figure 10a. Install the rectangular ends of the two hinge bars into the front rigging tubes the XLVC enclosure, as shown in Figure 10a, and secure each in the tubes with a quick-release pin having a green lanyard. Make sure that the hinge bars are installed into the rigging tubes on the enclosure so that the two holes on the back side of the tube line up with the two holes on the bars. If the holes do not line up, exchange the left and right bars. Install the large hex-socket-head shoulder bolt through the slot in the rigging tube into the rear of the front hinge bars. The head of this bolt will serve as a handle to move the hinge bars in and out of the tubes. On each side of the enclosure, insert one of the small hex-socket-head bolts through the tab of the lanyard securing the hinge bar and through the tab of another matching quick-release pin having a green lanyard, then screw the bolt into the threaded hole on the side of the enclosure rigging. The extra quick-release pin on each side will be used to secure the hinge bars to the bottom grid. The newly added rigging should match the hinge bar and lanyards at the top of the enclosure. The extra front hinge bars at the bottom can be retracted into the rigging tubes during transport. Secure the swing arms to rigging channels on each side of the enclosure by inserting a quickrelease pin having a yellow lanyard into the 3° hole on the rigging channel, as shown in Figure 10a. The extra quick-release pins having a yellow lanyard will be used to attach the loose end of the swing arms to the bottom grid. There is insufficient room for both sets of swing arms to be retracted into the rear rigging channel during transport. Therefore, the bottom set of swing arms and quick-release pins will need to be removed when the enclosure is transported. [. . . ] Damaged structural supports should be replaced or repaired and recertified by a professional engineer. Never exceed the limitations or maximum recommended load for the supports. Miscellaneous Mechanical Components: Prior to each use, inspect all mechanical components (chain, wire ropes, slings, shackles, hooks, fittings, ratchet straps, etc. ) for any cracks, deformation, broken welds, slipping crimps, fraying, abrasion, knots, corrosion, chemical damage, loose screws, missing or damaged components that could reduce the maximum strength specified by the component manufacturer. Replace any damaged mechanical components. [. . . ]
