2. Rigging and Flying Techniques
As shown in Figure 5b, the XLC-EB may be picked up using one pickup point or two pickup points. The
two pick up points may be raised and lowered as necessary to adjust the vertical tilt angle. When using
two pick up points, the pickup rings are usually installed in Holes #1 and #23 at the extreme ends of the
XLC-EB for maximum front-to-back stability. However, the pickup rings may be relocated to redistribute
the load between the front and back points. Holes #1 and #23 can only accommodate tilt angles of up
to 30° before the rings will contact the spacer bars in the beam assembly. When greater tilt angles are
required, the pickup points should be moved towards the center of the XLC-EB.
When using one pickup point, the vertical tilt of the array can be adjusted by changing the hole in which
the pickup ring is installed in the XLC-EB. The LAPS program can be used to determine which hole to use
to achieve the desired vertical angle.
Each pickup ring has a centering ring. The centering ring positions the pickup ring in the center of the
XLC-EB 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.
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.
For Shipping/Transport, the yoke and ring assemblies may be rotated into the beam assembly, as shown
in Figure 5c, so that all moving parts are recessed.
