A Tiller with a Pump?

[Ledebuhr1]

I saw in the recent issue of Fire Apparatus a Tiller made for San Bernadito FD, that had a pump and tank. Anyone know how these pumps get thier power? Is it from a seperate motor? and are they full sized pumps? like 1500gpm+?

Thanks

The tank and pump are located on the tractor, so they function just as a normal midship pumper would. All that I've seen have a full size pump (1,500 gpm+) and the typical quint tank capacity of 300gal. I've only seen one in person, so someone else might have more details.

Send a PM to CalFFBou....He can probably get you some details.

LA County has one,Truck 33 as mentioned above the pump works the same as a Engine. They just have a little less water.

Ok thanks. So if the pump is on the tractor, then there is no preplumed discharge from the pump to the ladder? I assume you have to connect a hose from the pump pannel to the tiller.

Yes it does have a pipe, they make swivels for the stick, right? Why not for the 5th wheel?

I would suspect that if one wanted a pre-piped, pre-plumbed master stream on the aerial it should be possible. With the articulation and also the fact that the trailer will pivot forward and back on the kingpin/firth wheel connection (imagine a tractor trailer in a sunken loading dock), a high pressure flexible hose (similar to what they use in a lot of pump houses now) could do the trick. I've never looked that close at the few tiller quints I've seen, anyone know for sure?

I have not seen them pre-piped ..............just that they have LDH intakes at the base of the ladder.............the first one I saw was from Encino Ca ? ........now I cant remember............dang it !

Was it Chino Valley, CA? They have an ALF TDA with a 1250 fire pump, and a water tank.

[Weruj1]

this isnt the one but it shows the intake !

I've seen a bunch lately with pumps and tanks and a few with tanks larger than 300 gal (i think, I have to double check). I had never seen one with tandem axles on the tractor until recently. I've now seen 4 or 5. Here is a pic of one, however this one only has a 150 gal tank so I'm not sure the reasons for the tandems, but I don't really have much info on this one.

That intake could also be the aux feed for the pipe. A preconnection would be buried under the hitch and not visible. If anyone can find a picture of the pump panel look to see if there is a valve dedicated to the stick.

Ladder 27, That is one HECK of a truck!! That thing is a monster. Is it from your dept?

LA County as well as several other fire departments out here in southern california run tiller quints

[gunnyv]

Detroit has traditionally run booster reels on their aerials. The last two batches of tillers from ALF and Pierce had dual boosters, pump, and tank on the tractor.

[STATION2]

LACoFD has more than one, quite a few actually. Some are 75' and some are 100' from what I recall and they are ordering more. Not being critical, just a thought. And from what I recall about them, the visible intake is simply an option should the aerial need to be supplied by a seperate pumper. I have seen alot of rearmount quints that have this also, I know both of ours in my Volunteer Department have this ability.

This particular rig was going to Utah, if I remember correctly. They were putting the finishing touches on it when I was in Appleton last time.

Charlottesville, VA has a tandem axle tiller (ALF), and their reason was for increased stopping power on a lot of the hills in the city.

I think the main reason for the tandem axles is for increased braking capacity.
