    Default 75ft quint/tank size

    what is the biggest tank anyone know of on a quint with a single axel. a neighboring dept. has an alf with a 1500gpm pump, with 750 gal. tank w/foamon a single axel. just wondering who else builds them this big. tank size will be a big issue when we get to specing our next truck which might be a quint.

    Default 75 Ft. Quint S/A Tank Size

    Are you sure the FD has a ALF with 750 G Water & Foam Cell??? I find that really hard to believe and not be over either a 31,000 or 33,000 lb. rating single axle UNLESS they've got minimal compartmentation and equipment carrying capacity and a crew of 50 lb. midgets (not trying to insult small people..)

    I don't know of any builder that could do that legally IE Axle/Tire load limits BUT there is always going to be a first.

    MOST of the OEM's can and do offer a 500 G tank size with a foam cell(s) in a 30-50 G capacity as well as having the ground ladders, compartmentation and equipment carrying capacity.

    Do you have the name and or photo of the FD that has this ALF..I'd sure like to see one...

    Why do people continue to insist on single rear axels for aerials?

    750 gallons is a bit much for a single rear axle quint. We have 500 gal tanks on our 75' single rear axle quints and they drive fairly well (although the Jake Brakes help out a bit ) If we were to get some more quints like them they probably would be on tandem axles because we are at the rigs GVW. I would in no way consider 750 gallons on a single rear axle.
    I can't believe they actually pay me to do this!!!

    One friend noted yesterday that a fire officer only carries a flashlight, sometimes prompting grumbling from firefighters who have to lug tools and hoses.
    "The old saying is you never know how heavy that flashlight can become," the friend said.

    A tandem axle really is a must IMO
    More load capacity, better braking and at times better traction when you can lock them.
    The turning radius of a single vs. a tandem really isnt all that much if any.

    750 gal on a single axle . We are just below the GVW on our Tandem axle 75' with 500 gal. 46k in the rear and 18k on the front.

    My department will soon be taking delivery on a 75' single axle quint. We where limited to a total of 500 gallons due to weight (500 gallon max of water and foam). It worked out to be 460 gallons of water and 40 gallons of foam. If you want more water than that I have to agree you should go with a tandem axle.

    Our dept has operated a single axle, 10 man cab, all steel cab/body/ladder, 75' rearmount with a Waterous 2 stage 1500GPM pump and steel 350 gallon tank since 1991. Braking and weight has never been a problem/issue. I would also point out that our truck has an 8V92 engine with a Jake brake on it, and anyone who has operated a truck with the Series 60 with a Jake knows it's much more effective as far as engine stopping power goes. Also, the newer Allison transmissions tend to be much more responsive as far as downshifting is concerned. Couple that with the ability of manufacturers to use much lighter cab/body materials such as aluminum, as well as the lighter aluminum wheels and poly tanks, more compact yet more efficient single stage pumps, electronic controls replacing many manual (and weighty) controls and you're talking an extremely significant reduction in overall apparatus weight. An aluminum ladder will only further reduce that weight. Newer independent front suspension systems increase front brake size and stopping power. Most single axle rearmounts are medium duty rated aerials anyway, good for around a 500 pound tip load. We're not talking 1500 pound capacity tower ladders here.

    These are just some important factors to consider before making sweeping statements such as "aerials MUST be tandem axle."

    Perhaps it's a Squrt? I'd agree, sounds too heavy for a single axle.

    If it's an ALF... get me the Vin Number & I can look in the vehicle file and see what size tank was installed.

    Take care, and be SAFE

    Default 2000 gal

    Fallon/Churchill has two ladder trucks that have 2000 gal. on each. But there rear twin axle's. Those are real war wagons.

    Fallon Does have some very well speced out trucks. Most departents would love to have what they have. Of course they must have the $$$

    I believe in this months Fire Apparatus in the "Now in Service" section. They have a 65ft ladder with full cabinets, full sized pump, and 770gals of water. I know its only a 65ft ladder, but I still think that truck has to be almost at GVWR when loaded. It was made by Spencer Fire Apparatus in Grand Haven MI.

    Default after further review

    i have heard rumors that the truck i mentioned was delieverd to a dept. and that dept. rejected it becasue it was overweight. obviously! so alf made it a demo and then sold it to the above menitoned dept. this is only a rumor, but i have heard it 3 times in the last week. and all were by those in the truck industry and all lost out the bid on the truck. but i still have no reason not to believe them.

    Isnt there a lot of liability in making a truck that is overweight? How would the receiving department measure weight? Would they take wheel scales to the final truck inspection and if it was overweight, reject it. Then do they get their deposit back?

    Default 75 Ft. W 750 G Water Tank?

    I'd sure like to see photos of this truck and can't imagine that the rear single axle isn't over weight..The maximum rear axle rating that I know of is a 33,000 lb. rating and based on this tank size, body, aerial device there is no way it can be under the 33,000 lb. axle rating unless they aren't carrying any equipment... Anyone got a photo of this apparatus to share?

    Because they save about $20 to $25 G's by not having a tamdem rear!!!! Doesn't make any sense to cut back on safety!!!

    I have trouble believing a mgr would build a truck knowing it was overweight or in danger of being so with the usual assortment of equipment, etc.

    Due to long narrow curved driveways and roads we spec'd ours this way (32 feet long). The other dept in town has a dual axle tower ladder which cant get to much of our district. We have a 500 gal. tank.
