HME designers and engineers were the first to bring the tilt-cab design function to the fire apparatus industry. Tilt-cab designs made the use of cab-forward trucks, with their shorter overall lengths and improved maneuverability, more practical for fire apparatus application. The introduction of the tilt-cab design also provides easier and more efficient access to the engine compartments lowering maintenance time and costs.
The water delivery system is the heart and soul of a fire apparatus. Your ability to effectively fight fires depends on the quality and reliability of your pump and valve control system. HME engineers have created an exclusive pump module design that provides maximum water flow and optimal versatility.
HME has made compressed air foam system technology simple and affordable with its innovative and exclusive MAD DOG™ CAFS. This patented compressed air foam system eliminates adjustments of foam proportioning and air injection valves. Simply charge the CAFS line with water, activate the foam system and push the CAFS button. The MAD DOG™ instantly supplies 150-GPM of fire smothering, long-range compressed air foam to quickly suppress wildland, vehicle and structure fires.
HME is the world’s largest single-source producer of custom, stainless steel fire apparatus. HME uses stainless steel almost exclusively in the construction of bodies and components because of the many advantages and benefits stainless steel has to offer in the tough and harsh environments fire apparatus face on an almost daily basis.
There’s a lot riding on the quality of your steering system. The maneuverability and safety of your crew and the public depend on the strength, engineering and integrity of your steering mechanism and design. Because steering and vehicle control is so critical in fire fighting applications, HME engineers have created a robust steering construction to meet the toughest demands in the harshest environments.
Fire apparatus engines operate in high-heat environments for extended periods of time. Ordinary engine cooling systems aren’t designed to stand up to the continuous heat and rigors of these testing conditions without eventually failing – causing severe engine damage or loss of fire fighting capabilities. To ensure extended and optimal engine cooling, under the most unforgiving and demanding conditions, HME has designed an exclusive cooling system that’s more than tough enough to take on hours of unrelenting heat and service.
HME leads the way again with the introduction of an High Performance Gearing for fire apparatus. While standard 6-speed transmissions are available for the majority of fire apparatus, the introduction of High Performance Gearing now provides departments serving hilly or mountainous regions an option that delivers significantly improved performance from responsiveness and fuel economy to improved engine and drive train life.
HME is the world’s first dedicated manufacturer of fire apparatus to introduce a 100% compressed natural gas powered fire truck to the fire fighting industry. The HME Ahrens-Fox® CNG is the first fire, EMS and rescue response vehicle powered by a clean emission, compressed natural gas (CNG) engine. This innovative and industry leading fire apparatus meets all present EPA emission standards without the use or addition of exotic filters or exhaust gas treatment devices. While the HME Ahrens-Fox CNG engine may be innovative and unusual, the quality and capability of this CNG fire apparatus is not – it carries all the advanced design features, capabilities, and quality engineering found in every HME Ahrens-Fox.
