I think he means the crane that used to be on top of the FSS?

Guess I never paid attention. And after seeing 39B so much lately I never noticed. Great seeing a bird on the pad again, as always. -

The Fixed Service Structure is located on the north side of each pad's hardstand. It is an open framework structure about 40 feet (12.2 meters) square. A hammerhead crane on top provides hoisting services as required in pad operations. There are 12 work levels at 20-foot (6.1-meter) intervals. The height of the structure to the top of the tower is 247 feet (75 meters), while the distance to the top of the hammerhead crane is 265 feet (81 meters). The 80-foot (24-meter) fiberglass lightning mast tops off the Fixed Service Structure at 347 feet (106 meters).
The Fixed Service Structure has three service arms. They are the Orbiter Access Arm, the
External Tank Hydrogen Vent Line Access Arm and the External Tank Gaseous Oxygen Vent Arm.
The hammerhead cranes were later removed (pad A in 1994 and pad B in 1995) due to the high cost of maintaining them. It was decided that, since a ground based crane could be used, it was cheaper to remove and scap them, than it was to refurbish them.

Am I right in assuming these were the ones used on the apollo towers?

Nice smooth roll to the pad. Thanks for the coverage guys. Was in school and catching up.

Looks like part of the crane still is in place on Pad "B"...see photo of STS-116 roll out.

The top of the FSS on Pad "A" seems a lot "cleaner". See STS-117 photo...

Im just noticing the crane being gone--was trying to figure out what was missing--why it looked different. Ive been watching all these yrs and i dont think i ever noticed the cranes were removed until you folks just pointed it out.

What sort of things would that crane have had to move? Not spacecraft components, surely...

Used for pad maintenance. Replacing parts of the structure and moving pad hardware. -

It was used for lifting items too big for the elevator also. The orbiter escape pole is one of these items -

Thanks for clearing that up. I was wondering what happened to the cranes. The only one now left is seen in the Saturn V Center building. Man, seen so close it make you appreciate the scale of the parts used.
I can't see that well the current Pad A look. What does the top of the FSS look like close up? Also are there any photos showing Pad A being retrofitted? -

Regarding the crane, the base was in place on A until recently; it was there for 107 (as it is on B still).
I've posted rollout photos on my website if interested. -
