GEO TANGENT ARRAY RIGGING SYSTEM
Extension Bar
Figure 7
Figure 8
The GEO Bumper has two lift points, which are adequate for many situations. The extension bar is designed
for those applications where the bumper’s lift points are too close together to allow setting the proper tilt angle
for the entire array. With 16 GEO cabinets, a vertical GEO array can be tilted ±15°. NOTE: Always use an
inclinometer and/or a laser aiming device to verify that the array has the tilt angle specified in NS-1.
The extension bar has several tilt-angle adjustment points. It must always be secured by inserting two of the
supplied 12mm pins into two of these points: pins must be locked in place with the supplied R-clips. The GEO
bumper, with or without the extension bar, should be lifted by a single motor hoist using the two adjustable
chains connected to a central flying ring (see Figure 8).
CD12 BUMPER
The bumper of the CD12 is an independent hardware element that enables GEO users to fly one or more
CD12’s either alone or directly behind a GEO array. The CD12 bumper is shipped with four link steels. To
connect the top CD12, attach these steels to the four rails located on the bumper and the four rails located on
the CD12 (Figure 9).
