Or this size ??
F.D.N.Y. - Guest - 08-09-2009
I think the bigger one looks better.
F.D.N.Y. - gjh119 - 08-09-2009
J....the bigger one!
F.D.N.Y. - Guest - 08-09-2009
the bigger one is the better one, nice pic of the macks <img src='http://www.firepics.net/groupboards/public/style_emoticons/<#EMO_DIR#>/luxhello.gif' class='bbc_emoticon' alt='

OK, Thanx, big ones they will be ! One more for now, RAC unit (ex-NYC*EMS Bus)

[quote name='JFong' post='328104' date='Aug 8 2009, 19:43 ']Thanks for the heads up! Has photos, drawings and a good detailed spec sheet on the page.
I wonder if the truck was also rejected due to the new style "cat tracks"? They seem to be sticking out a bit off the sides.[/quote]
I read on another board that it was indeed the "cat tracks" that got it bounced.
You can definitely tell that's an FDNY spy shot. Check out the windshield wipers. FDNY, thus far, is the only recipient of Marauder II rigs I've seen with that configuration. All the others are the same vertical, parallel, two-arm wipers that you see on KME, ALF Eagle, older Spartans, etc. But, for some reason, FDNY is getting theirs with single arm, horizontal blades that point toward each other. Hmmmmm.......
Does anyone know the reason why this is?

Just rite I was able to see 266 on this one ......Keep them coming...
F.D.N.Y. - tntway - 08-09-2009
ok.....i'll bite........forgive my stupidity but what are "Cat Tracks"?
F.D.N.Y. - Guest - 08-10-2009
Cat tracks is a description of the new method of bringing electrical power up to the bucket. Previous versions of aerialscopes used a reel and cable that was underneath the boom. This method only allowed a certain number of individual conductors because of the size of the cable and the reel. In previous years it wasn't much of a problem, because most people who wanted an aerialscope didn't want or need much power in the bucket.
Now with all of the major electronic components on a platform, plus the desire for more lighting and other accessories, there needed to be a way to get more power up to the boom.
The reels didn't cut it. If you look inside the sections of any modern aerial platform, you will see a cable that is about 6" wide, lays flat, and has links, like the tracks of a caterpillar. This is the "cat track".
Since the aerialscope boom is a sealed component unlike a conventional ladder tower like an LTI or Pierce, Seagrave opted to build a little tray, maybe 10-12" wide, alongside the curb side of the boom, and leave the top of it open and lay the cat track inside this tray.
When the boom is anything but fully extended, the back of each section has a loop of the cat track that extends up and out of the track about 1-2 feet. It looks to many who have seen this arrangement that the cat cable could easily be hooked on something during firefighting operations. because most of the people who use aerialscopes, like FDNY, use the scopes at all kinds of low angles and in very close proximity to structures and trees and wires, it doesn't make sense to have something that could get caught on a foreign object.
if the cat track got caught and pulled out, it could either pull out and break, rendering the electrical controls to the boom inoperative (very bad) or it could hold the boom until enough hydraulic energy was built-up releasing the boom and it would bounce very hard away and potentially throw the FFers out of the boom (which has already occurred on parapet walls).
either way, not a great situation.
i do not think anything has been officially released about the FDNY situation with Seagrave, but the fact that they list a demo unit built to FDNY specs on their home page means something has happened. Hopefully it can be worked out.
here is a link to a photo that should illustrate the cat track:

Can anyone located a photo of the old Ladder 179 (Mack CF Tower) working a job. One of my guys at the airport has the rig and was looking for a shot of it actually doing the deed.

Thanks for the link, Chief66. Even in the link, the loops are sticking up pretty high and the ladder isn't fully extended.
F.D.N.Y. - tntway - 08-10-2009
Chief 66 thanks so much for an EXCELLENT explanation and the pics really illustrated the issue. i have a MUCH better understanding now!!
F.D.N.Y. - Guest - 08-10-2009
Chief66 thanks for the information, hopefully there will be a resolution to this the FDNY needs some new TL's fast.
