Huckbolt Engineering



Unmatched Performance in the Most Demanding Applications

Constructed using patented HuckBolt fastener technology in lieu of less reliable seam and joint welding, each Sutphen fire apparatus leaves our manufacturing facilities primed for many years of sustained community service.

Vibration-resistant HUCK C6L-B fasteners install with consistency and control and resist loosening due to vibration as they provide high uniform clamp force.

A: After inserting the pin into the prepared hole, the collar is placed over the pin. B: The nose assemble (orange) is attached to Huck's installation tool, over the pintail (white) and against the collar. C: The nose assemble pulls on the pin, drawing the sheets thogether and swaging the collar into the locking grooves. D: The nose assemble continues to pull until the pintail breaks off. The nose is pushed off the swaged fastener.

Besides Sutphen fire apparatus, HUCK Industrial Fasteners technology and tooling are used in the manufacturing of a wide range of high-quality, performance-demanding products - from commercial and military aircraft, automobiles, buses, and railcars to trucks and truck trailers, HVAC equipment, satellite dishes and more. As a result, the HUCK C6L-B is an excellent fastener for a wide range of sturctural applications for Sutphen apparatus.

As part of the Alcoa Corporation, HUCK International Industrial Fastener Division has the required resources to meet the fastening requirements of Sutphen's growing fire apparatus business. While HuckBolt construction costs a bit more, your investment is more than compensated by improved apparatus performance and long-range durability.

Box-Boom Design
Sutphen's 4-sided box-boom design performs like a tube, providing maximum rigidity versus most other brands' 3-sided open-channel designs, which can twist from wind and weight. This box-boom technology and HuckBolt fasteners are two of the major engineering factors allowing Sutphen to offer a lighter, taller telecopic platform with the highest fully extended flow rate in the industry. The lighter aerial gives Sutphen a lower Gross Vehicle Weight Rating (GVWR) on tires and axles versus competitors' products. And because all apparatus manufacturers use the same size brakes and engines, this means Sutphen apparatus offer superior braking performance and better acceleration than the other, heavier apparatus on the market today. Lower overall weight means that Sutphen aerials only need two "out-and-down" outriggers for support - one on each side - versus the four required on comparative trucks.
Mid-Mount Technology
Compared to rear-mount aerials, Sutphen's mid-mount technology offers many clear advantages. It allows Sutphen to mount its booms lower than rear mounts that are postioned over the cab. This inherently lowers the truck's center of gravity providing superior handling and maneuverability. The position of the aerial and pivot point make it easy to place the aerial over the cab at less than 10 degrees elevation. The travel height is greatly reduced with the mid-mount as low as 9" - 10".
Lower Overall Weight
Sutphen apparatus typically weigh 7 to 10 tons less than competitive apparatus. This lower weight allows Sutphen to provide stainless steel bodies, increased water capacity, larger hose loads and greater compartmentation.
Bucket Design
Mid-mount technology also allows Sutphen to locate the platform near the ground and at the rear, providing for Sutphen's trademark "easy in easy out" platform. With rear mounts, personnel have to either climb or horizontally walk the ladder or raise and lower the aerial to enter. When raised, Sutphen buckets are suspended above their own centers of gravity on a yoke attached to the sides of the aerial. This allows the bucket to naturally level itself in the unlikely event of a leveling system failure. All other makers support the bucket from its bottom which requires more leveling equipment.
Turntable Technologies
Sutphen turntables are attached to two torsion bars - one each, fore and aft - to evenly distribute weight and stress on the chassis frame eliminating the need for a torque box. The absence of a torque box gives Sutphen the ability to carry up to 500 gallons of water and still hold 1000' of 5" pumper-style hose.
Waterways Design
While some manufacturers offer dual monitors as an option, Sutphen incorporates two 1000-GPM nozzles as standard equipment. The inverted waterway design is unique to Sutphen aerials. Where most other apparatus waterways are large at the bottom and reduce in size as the height increases, the Sutphen design starts at its smallest size and is largest at the end of the last fly section, thus promoting unsurpassed flow characteristics. Another disadvantage of competitors' three-channel designs is that the waterway is always positioned under the boom, exposing it to damage. With Sutphen's box-boom construction, the waterway is totally encased inside the boom for optimum protection.
