The 55' Heavy Duty Aerial is designed for single axle configurations. The base Quint model meets all requirements of NFPA. The aerial is rated with a 500 lb. tip load while flowing 1,250 GPM at 0 degrees elevation 90 degrees perpendicular to the aerial device. This allows for no restrictions in the operation of the aerial device. This apparatus offers pump configurations from 1,250 GPM through 2,250 GPM, utilizing Waterous, Hale and Darley pumps. The tank configurations are from 300-750 using Poly tanks. Smeal also offers a variety of hose bed configurations on the 55' Heavy Duty Aerial including our exclusive EHL (Ergonomic Hose Load), EZR (above the right side compartments), EZ Load (allows high side compartments both sides, with two hose beds) or ahead of the turntable with hose chutes. The Smeal exclusive CP-84 Waterway is the strongest, most durable waterway on the market and is standard on this model. A galvanized inner coating prevents corrosion of the 84,000 psi pipe while the exterior waterway is chrome plated to provide a smooth telescopic movement throughout the entire extension and retraction of the aerial ladder. With more than 8,000 available features and options, Smeal aerials are safe to operate, easy to control, and capable of maximum performance.
