New E-ONE TITAN® 4×4 ARFF Rig Takes Inspiration from Customers

E-ONE Titan 4x4

The new E-ONE TITAN® 4×4 aircraft rescue and firefighting (ARFF) vehicle is markedly different from its predecessor, now showing newly-redesigned styling inside the cab, as well as a number of bold angles, sweeping edges, and seemingly acres of windshield and side glass, taking many of its cues from what matters most—customers.

The new TITAN cab and windshield slopes forward and sits lower on the body in order to allow greater visibility for the driver and other occupant than found in previous models. Likewise, the top turret also is positioned lower and out in front of the rig’s operator, so that it’s almost like sighting down a gun barrel at the target, instead of needing the operator to look at an upward angle to see where he or she is placing the water stream.

E-ONE’s international ARFF product manager Matthew J. Reda observes that the whole idea is to put water (or another extinguishing agent) on the fire, and in the case of an ARFF vehicle, while pumping and moving at the same time. Reda says having the top turret extend out in front of the operator makes it much easier for the operator to have a better line of sight as to where the extinguishing agent is being placed. There is also the option of having the Rhino high-flow low-attack bumper turret which can also act as a primary turret, again providing a better line of sight to placement of extinguishing agent.

Visibility is another main area where the new TITAN 4×4 excels. The new ARFF’s windshield is larger than in the past and is set lower in its frame, giving exceptional frontal visibility for its occupants. With the new windshield design, an average size operator in the driver’s seat can see as close as nine feet in front of him, an improvement over traditional windshield designs.

The new design of the TITAN 4×4 includes a cockpit style cab that wraps around the driver, translating into better visibility and greater situational awareness. Reda likens the new design of the cab interior to a military helicopter where all cockpit controls are located to the center and front, and available to both the driver and first officer of the vehicle.

The driver sitting in a new TITAN 4×4 ARFF rig is able to control the vehicle functions including pump, turrets and handlines, auxiliary agent, and climate control plus all lighting using a multiplexed system. The functions are controlled through a center-console-mounted touch screen as well as a newly incorporated smart steering wheel with programmable switch pods all designed to make vehicle controls intuitive for the driver.

Another exclusive feature of the new TITAN design is increased compartment space, with a total of 360 cubic feet of usable equipment storage capacity between eight compartments. The L1/R1 (left/right side) compartment is designed to house water/foam, dry chemical, electrical, and air hose reels and also has a narrow transverse section between the L1/R1 compartment that can be used to house a backboard.

The L2/R2 compartment houses the pump, the pump panel controls, inlets, discharges and all pump plumbing, which used to be scattered around the vehicle. The location of all pumping components in one location makes the vehicle easier to operate and maintain.

L3 is a larger lower compartment with a slide out, which is mirrored in the officer’s side R3 compartment. Typically, preconnects are located in these compartments.

L4/R4 are full-height compartments with an upper section containing a full transverse section between them, while L5 and R5 are rear-body compartments with roll-out, tilt-down trays. This rear body section is new to the redesigned TITAN 4×4, adding valuable storage space to the rig.

Both the engine and the pump have been changed on the new TITAN 4×4. Because of newly legislated emission standards and an outstanding international service network, E-ONE chose to power the TITAN 4×4 with a Scania 670-horsepower (hp)—or optional 770-hp—Tier 4 diesel engine coupled with a Twin Disc six-speed automatic transmission.

The pump change was made to a Hale 8FG rated at 3,000 gallons per minute [11,356 liters per minute (lpm)], although the pump is capable of providing greater flows from a pressurized water source.

Rounding out the fire suppression capabilities, the TITAN 4×4 has a 1,585-gallon (6,000-liter) water tank, a 225-gallon (850-liter) foam tank, 500 pounds (225 kg) of dry chemical, and it can pump any mix and any combination of those three products through its Akron AkroChem technology nozzles where dry chemical is encapsulated in the water stream, allowing the dry chemical to be propelled farther.

The TITAN 4×4’s standard roof turret is rated at 750 gpm (2,840 lpm), with a dual flow capability of 375 gpm (1,420 lpm) and a bumper turret capable of 250 gpm (950 lpm) or more.

Access to the top of the TITAN 4×4 now is accomplished by an industry-leading 56-inch-wide ladder that is an integral part of the rig’s body, with a fold-down section that safely allows two firefighters to ascend or descend to or from the top deck. At the rear of the vehicle on each side of the ladder are large “bat” wing door assemblies that open to allow ground-level fluid fill and inspection points to the engine and powertrain. On top of the rear body is 5×6 foot engine access hatch that makes it easy for servicing.

With this major redesign of the TITAN series ARFF vehicle, E-ONE has given firefighters more power, optimum control, greater storage, increased extinguishment capability, payload capacity, and serviceability than ever before.
