Single or Dual Axles for Your Next Fire Apparatus

There appears to be an industry trend to maximize loading on single rear axles, especially on tankers (tenders) and some of the recently introduced aerial devices.

The trend isn’t new, nor is it restricted to rear axles. Manufacturers have been challenged with axle weights for decades. Getting a comprehensible answer to the question, “How much weight can I put on this axle?” is as difficult as asking what the weight distribution should be or has to be between the front and rear axles. Asking, “When should I go to a tandem rear axle?” can be equally frustrating. Purchasers must rely on the advice, expertise, and integrity of fire apparatus manufacturers (OEMs) to find the correct answers. That is problematic when inconsistent or ambiguous answers are given. Purchasers shouldn’t be overly critical of OEMs who give conflicting answers about axle ratings. They must negotiate a labyrinth of governmental regulations at various levels, recommendations by recognized fire service and industry-affiliated organizations, as well as the requirements of National Fire Protection Association (NFPA) 1901, Standard for Automotive Fire Apparatus. Each answer might be correct in its own context.

Axle Ratings

To understand how ambiguities can occur when discussing axle ratings, it is best to define the ratings. Fire trucks are commercial vehicles. NFPA 1901’s Annex B states: “This annex is not part of the requirements of this NFPA document but is included for informational purposes only.” Included in section B.2.6 is: “Since the passage of Public Law 89-563, the National Traffic and Motor Vehicle Safety Act of 1966, the federal government has adopted certain motor vehicle safety standards applicable to all manufacturers of trucks, including fire apparatus. It is unlawful for a manufacturer to deliver a truck not in compliance with these federal standards. These federal safety standards are frequently changed, and their provisions make the incorporation of certain features and devices mandatory. Apparatus manufacturers cannot build apparatus to specifications that would require them to delete required items or to include any that are illegal, and they face substantial penalties for infraction of these rules. The italics are mine for emphasis. I don’t know of such a thing as the NFPA police. I don’t know who or how one determines illegality or liability or what the penalties could be. But, I’m reasonably sure the OEMs don’t want to find out.

The point of origin for the rules and regulations for commercial vehicles including fire apparatus lies within the bowels of the United States government. It could be the United States Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) or some other agency that generates rules or regulations that are published in the Code of Federal Regulations (CFR). They become administrative law and are, in turn, published in the Federal Register. It is immaterial and too time consuming to establish which agency established what, when, and why. From the point of origin forward, the “understandability” of axle ratings appears to go downhill.

Camera Systems for Fire Apparatus Provide Safety and Security

Fire departments worldwide are rapidly embracing the use of video on their fire apparatus to increase safety and security. Video and recording technology is quickly evolving from basic backup cameras to multicamera video systems that provide operators greater visibility and high-tech recording and that deliver much more than the video.

Fire Apparatus Manufacturers’ Association (FAMA) member companies are seeing increased interest in camera systems on new apparatus. Let’s take a look at some of these products, their features, their benefits, and what a second set of eyes can do for your safety initiatives.

Driver Visibility and Awareness

The most common use of cameras is to provide the apparatus driver with improved visibility. Relatively inexpensive camera systems may increase safety around the apparatus, avoiding costly accidents. Proximity sensors are also becoming more popular to provide additional awareness to the driver when the apparatus is nearing an object. Common systems currently being used on apparatus in the emergency market include the following:

  • Rear-View Camera Systems: Similar to those used on passenger cars, providing in-cab views and activated by reverse mode.


  • Blind-Spot Cameras: Typically used with a rear-view camera. Second and third cameras mounted on each side of the apparatus are activated by the turn signal to provide views accordingly.


  • Forward-Facing Camera: Usually used with rear- and blind-spot cameras, making it a four-camera system. A forward-facing camera, placed either on the front bumper or top of brow, provides the driver with greater visibility when positioning the apparatus.


  • 360-Degree “Bird’s-Eye View” Camera Systems: Typically four wide-angle (180-degree) cameras mounted on each side of the apparatus. A control module “stitches” images to create one simple view around the apparatus. The resulting image is a 360-degree bird’s-eye view that appears like it is coming from above the apparatus, virtually eliminating blind spots. These systems typically use a split-screen monitor: one side displaying the 360-degree view and the other toggling between the individual camera views. The view selection can be made automatically for the driver based on transmission shift selection (drive or reverse) and turn signal indication (left or right).


Proximity Sensors

A proximity sensor will detect the presence of an object or obstacle. The majority of proximity sensors in use today incorporate ultrasonic technology because of its economical price and good close-range accuracy. Placement can be anywhere on fire apparatus and, in many cases, integrated into a camera system, providing on-monitor sensor location and distance to object.

More Departments Choose Smaller Fire Apparatus to Handle Typical Runs

Many fire departments around the country are moving toward smaller fire apparatus to handle emergency medical services (EMS) runs and nonstructure fire calls to lighten the load that’s been placed on first-due engine and truck companies.

Ford F-550-chassis-sized vehicles are becoming popular in that role, meaning fewer hourly operating costs, reduced maintenance costs, and savings in wear and tear on the larger fire apparatus.

Joe Messmer, president of Summit Fire Apparatus, says that when fire departments go to a smaller chassis vehicle, “It’s mostly to lighten the load on engines and aerials that are running on EMS calls. They are having us build rescues on Ford F-550-size vehicles that can handle popping a vehicle’s door and assisting other EMS units.” Messmer notes Summit also has built such rescues on Ford F-450 chassis as well as on Dodge 4500 and 5500 chassis. “With squads, we build an enclosed utility rescue body with six compartments that can be customized for the application the department wants, whether more rescue or more medical.”

Cost Factor

Jeff Morris, president of Alexis Fire Equipment Company, points out that economics can be a driving factor when a department chooses a small-chassis vehicle. “The economy is still having an effect on budgets,” Morris observes, “and with the cost of running big rigs out on every call, many departments are looking toward smaller vehicles, which cost less and are easier to maneuver. Departments are comparing $185,000 to $210,000 for a smaller chassis vehicle to a Type 1 custom pumper that costs between $450,000 and $600,000.”

Todd Nix, apparatus consultant for Unruh Fire, echoes the issue of budget restraints having an effect on cities and fire departments. “Many of them are making changes to enhance their response while trimming their budget and lowering operating costs,” Nix says. “That’s where the smaller apparatus come in, which is basically our bread and butter. And, staffing is definitely a part of the trend where across the country volunteer fire departments are seeing fewer firefighters show up. They don’t want one or two firefighters on a full-size pumper to an EMS call when they can jump into a smaller vehicle and do it safely.”

Small Vehicles and Staffing

Brian Connely, account manager for Spartan ER, points out that many departments are trying to squeeze all the equipment from a traditional pumper into a smaller unit. “They want a rig that can be used for an EMS squad, at a motor vehicle accident (MVA) rescue, and for wildland fires,” Connely says. “The cost of ownership is one of the reasons, both for the initial cost and the cost of operation, as well as because of staffing issues. We’ve seen this happen all over the country, very often in rural volunteer departments, but also with some career departments too.”
