Sutphen
Sutphen is an emergency services vehicle manufacturer and marketer based in Amlin, Ohio. Sutphen was founded in 1890 by C.H. Sutphen. The company has four manufacturing plants in Dublin, Amlin, Hilliard, Springfield Ohio and Lake Ariel, PA. Products. Sutphen produces all types of fire related vehicles on their own chassis including the usual engines, ladders, and rescues but also provides bodies for commercial chassis applications. The company produces mid-mount aerials as either a tower ladder platform (with a bucket/basket) or in a ladder tower form (no bucket) plus industrial application aerials today. On April 21, 2016 at  FDIC International the company debuted its first ever rear-mount aerial with the Sutphen SLR 75. The following year Sutphen previewed a 108-foot model. Previously, Sutphen had produced tillers in the 1990s including a unique tiller-tower concept where the bucket of the tiller aerial also acted as the tillerman's cab. The concept never made it to production. All Sutphen aerials are made of Aluminum alloys and fastened with aircraft-type Huck Bolts. The hydraulics are custom designed and built by the company for their applications. Sutphen introduced its tower ladder in 1964 mounted on a Ford C  chassis but production models were mounted on larger chassis including Duplex and GMC. Models were 65, 75, or 85 foot models using three boom sections. Ground ladders were stored in the rear of the vehicle plus additional ladders on one or both sides of the body above compartments. The later addition of a 100-foot model used four boom sections and even later the "Magnum" 110 foot model used five. The SPH-100 model was introduced in 2004 originally on the short-lived Imperial chassis with production on the Monarch chassis. This model uses five boom sections to reduce overall length  and raised a much larger bucket/basket above the chassis body. All ground ladders are stored at the rear of the vehicle to increase compartment space although side-mounted ground ladders are an option. On February 25, 2021, Sutphen announced it would return to manufacturing tractor drawn aerials (TDAs or tillers). The aerial device is the same as the SL models. A preview video was released on March 25, 2022 stating the first new TDA would be at FDIC. An announcement video for the "SLTDA 105" released on April 28th, 2022. Aerial platforms. Mid-mount aerial platforms utilizing Cummins, Caterpillar , and Detroit Diesel engines, Allison transmissions, Hale and Waterous pumps. Aerial ladders. SL models have open framework booms for climbing same as traditional aerial ladders. SA models use the enclosed box boom design of Sutphen platforms. SLR models are rear-mounted as opposed to the others being mid-mounted. Pumpers. Sutphen has 2 pumpers: Guardian and Shield series pumpers. These have been consolidated to a custom pumper built on a Monarch Chassis and proprietary Monarch cab. Heavy rescue. A 6 to 10 man truck capable of carrying generators, air tanks, lighting, ladders, pike poles, crowbars, dive equipment, and other specialized  firefighting tools for use as heavy rescue apparatus, a HazMat vehicle, an Urban Search and Rescue, or Mobile Command Center. Extreme Duty Chassis. Sutphen's heavy duty chassis series included the Ambassador, Imperial, Monarch, and "S" Series.
