Thread: 75' quints weight question
04-13-2006, 06:12 PM #26
I've also heard the complaint that a tandem will "eat" rear tires due to the scrubbing nature when turning. I know the city where I live has a tire wear problem on their large 105 foot quints, but they run them on EVERYTHING - fires, EMS, the works - and they see a lot of use and miles. I think they were getting about 8,000 miles out of a set of rears, but I don't think it was the entire set of tires on the tandems that needed replacement, just four.
Personally, I see this "negative" easily being offset by the increased braking power and the larger equipment/water load allowed by the tandems.

okay what do we need then?
we want an elevated master stream. rescue capabilites, access to roofs, 2-3 story window. single axel. atleast 400-500 gallons of water. foam tank. with engine equipment. on a spartan chassis. would like this truck to be a do it all, except rescue just ordered a rescue pumper. we have a 2,000gal tanker.michael umphrey

75' quints weight question
You want the ten pounds of sh_t in the five pound bag. With that kind of weight on the vehicle 400-500 gallons of water and foam, along with your NFPA equipment weight, and we know we usually exceed that in most cases, you will not be able to stop the aerial in in a few short years, within the same distance as when it was new. The Spartan chassis has now one of the tightest steering crimp angles of any chassis offer today. That being said, look at a manufacture that can offer you a nice short wheel base tandem. You now can carry the weight, have the manuverability, and effectively have the addtional braking power.

We are currrently running a 1992 E-One Cyclone 75' Quint and have a 2 ton cusion between out operating weight and GVWR.
Specs are as follows, 1992 E-one Quint, 75' Aluminium stick,10 man Cyclone cab, 1750 Hale QSMG pump, 400 gallon poly tank, 500 hp 8V92 Detroit, Allison HT-740 Auto Trans, 20,000 front axle, 31,000 rear axle, 1000 5" LDH, 600 ft 2.5", 800ft 1.75", 5KW generator, 2,200 gal Portable tank, Ground ladders (35',2x 24',2x 18' roof, 2x 14' roof, and a Little Giant), and a healty assortment of truck tools.
GVWR is 51,000 we weighed in at 46,900 with driver and officer.

The GVWR usually isn't the weight restriction that most 75' aerials on a single rear axle run into. It's the weight on the rear axle, most of which are rated at 31,000 lbs. It's very easy to exceed that weight rating on such a truck. However, it's certainly possible to be under the total GVWR, so you need to specifically look at the rear axle weight rating.

Here is a thought:
If you take an aluminum mid-mount, you can save 10k in weight and therefore have no need of another axle. It will stop quickly, ride nice, turn sharp, carry 500 gal of water and still have lots of room to spare for the required ISO equipment before even coming close to the axle ratings. Food for thought......I have but one ambition in life and that is to become a firefighter.

Rough ridin Quint!
We have a Pierce Dash 75' Quint with the tandem axle. Has anyone noticed how rough a ride these things have. My gosh I thought I was gonna hit the roof a couple times just going 5 miles over the speed limit to a call. The mechanics have said due to the weight in the back you are picking up the front wheels a little bit making for a rough ride. Cant wait to get back to my Tak-4 engine.

I just saw a magazine advertisement for HME
it said they have developed a quint with 750 -1000 gallons on a tandem rear
I think they use RK arials

Once you add that second rear axle, you can do alot of things. I know of at least a couple of units with bigger water:
750 gallons with an 85 foot tower ladder
1000 gallons with an 85 foot straight stick
Both were built within the last few years. HME chassis are under both of these units, but HME did not build the bodies. I don't see any reason why they coudn't have been a Spartan or any other custom chassis builder.

Dont forget the Fallon ladders. they are 62ft. and carry 2000 gallons of water. They also have a lot of foam, and every tool known to man.

Is a truck with a 62' aerial even considered a Quint?

There is no height requirement to make Quint status, only that it have an aerial device. Also, Sutphen has produced a few tandem axle trucks with 750 gallon tanks and 75' sticks. I believe West Metro Missouri has them.I have but one ambition in life and that is to become a firefighter.

You'll want it to have all the necessary pumper attributes to take on the fire (decent pump, decent tank [400-750gal.], decent hose load [couple crosslays, enough LDH to hit the nearest hydrant, 2.5"/3" blitz/bomb line], and you should at least consider CAFS. You also want rescue/ventilation capability of a Quint, so you're gonna need ground ladders, saw, vent fan [or PPV] at a minimum. The elevated master stream device and handtools would come whether you were specing a ladder or pumper, so you get a two-for-one deal there.
The only controversial things in this basic list is the length of ladder and size of the water tank.
You say you want to reach 3-story windows, but you have to watch your set-backs. We have some areas in town where we need an 85' ladder to reach the second-floor windows of some houses, because there is a hilly, dirt front yard and the house sits back 60+ feet from the street... Also, if you're specing a short-stick quint w/ a single axle, forget about the platform option. (Just my opinion, but it seems like over-kill on such a short stick. If you need two nozzles, check out Sutphen, they'll put two master streams on a short straight stick. Others may also.)
You say you want a single axle and you say you can live with a 400-500 gallon tank, so I took your word for it and wrote it in my general idea above. BUT, you also say you have a tanker, which implies you don't serve a fully (or any) hydranted area. If that's the case, and you plan to use this Quint as your first-in unit, I'd say forget the single rear axle and spec at least a 750, or better yet, a 1000 gallon tank. It would be quite embarassing to roll up with your $750k quint that can "do-it-all" and run out of water before getting the fire out... (It's happened to us, so I'm not pointing any fingers that I haven't pointed at myself...)

Excellent Points mentioned immediately above!
Dear MMA10mm, your points innumerated in this above post are right on the money, IMHO.
And, to mic409; Although there are a number of manufacturers that can fill this bill quite nicely, I know of none who could do all of it AND add a platform, too, all on a single axle; nor should they; -again, IMHO. The 75 foot aluminum ladders are where the weight savings in a maximum combo apparatus would come from- savings that would allow for a 500 gallon water tank. Here, we're primarily talking about either Pierce or E-One. But again, no platform, not without a double rear axle. Smeal's 75 foot steel-laddered aluminum-bodied quint, with the ELH waist-level retracting hose bed, a 400 gallon tank, and compartments on both sides at both lower and upper levels on each side just might meet your needs for a do-all initial response apparatus better than many others. But, you DO have to get it with a larger engine and a beefier Allison EVS4000 transmission to move all that weight; even with it all on a single rear axle. And, they DO by the way come on a Spartan chassis, as well. One last point; you're not going to get a large (750 or more) water tank on any aerial device with a single rear axle, as I believe was the request: the tradeoffs in both weight and room are just too great. However, you could use the strategy of having a smaller water tank go farther and work more efficiently by equipping it with a computerized foam system. Many departments do this, including ours. It is claimed that by using a foam system in this manner, that the water effectiveness is increased from 3 to 5 times that of plain water alone- thus compensating for the smaller water tanks that such multi-purpose, single rear axle aerial apparatus must -of necessity- have. Hope this adds something to your considerations. Good luck in your search. Let us all know how your plans are evolving over time.

"THE ARSENALTM HAS ARRIVED
Why settle for a quint that doesn't carry as much water as your pumper, and can't provide enough storage space to carry a full ISO compliment of ground ladders and equipment? With tank sizes up to 1,000-gallons, exclusive HME Ahrens-Fox Hydra TechnologyTM water delivery systems supplying up to 2,250-GPM, and either 75' or 109' heavy duty ladders with 25-year corrosion warranties, the Arsenal provides all the firepower you need with no compromises.
