Single Rail verse Double Rail Frame
Hey all. I need some help with a very critical issue we are facing. We are in the process of specing out a tanker to be purchased through the AFG program. It will have a 3000 gal tank, 750 pump and a crew cab. We were reduced in price to $250,000 and are having a terrible time finding a manufacturer able to supply such a unit in this price range. We do have one quote offering to complete this purchase for right around the grant amount. The problem is that the chassis does not have doubled frame rails. Will this unit still be safe without the double rails? Or would we be making a mistake by making this purchase? Thank you for your help.
Single Rail Vs Double Rail
Listen to Vanisle EVT and other's DON'T even consider a Single Rail for this application and the difference should only be maybe about $1,000-1,500 for a Double Rail.
Also depending on the body design have you thought of or would a Wetside Tanker work with the 3,000 G and 750 GPM Pump? Take a look at Danko Emergency Products, S&S Fire etc.
No more double frames for us!
I have little experience with fire trucks, but I have extensive experience with highway plow trucks. It is a different kind of abuse, but it's still abuse. The impact these trucks take on the framerails forward of the front axle and the side impact they take because of the rear mount for the side wings is incredible. The difference is the single frame is able to be cleaned and therefore lasts longer. Double frames hold the corrosives between them. By the time a problem is visible, it's too late.
Sterling recognized the the problem and developed a single frame rail strong enough to meet most requirements. When we bought our last truck, Peterbuilt still had not addressed the issue. It all depends on the manufacturer of the frame, but double frames don't always exceed the specs of a well designed and manufactured single frame.
