ALWAYS MAKE SURE THAT EACH
As shown in Figure 9d, the CBEAM 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 #30 at the extreme ends of the CBEAM for maximum
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 CBEAM. 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 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.
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.
