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 still 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.
