Good question – the most current NFPA-1901 (2003 Edition) does in fact include a section (#20.2.12) which deals with aerial speed, BUT in reality it is to establish a MAXIMUM time for aerial operations, not minimum (as in “speed”).

All aerial models (110’ & below) must be able to fully raise, achieve full extension, and rotate 90-degrees (1/4 turntable rotation) all within 120 seconds. As you can imagine, some Fire Departments feel that a full 2-minutes can feel like an eternity during any fireground rescue operation, so some aerials have been designed to operate faster than others; as you most likely saw in Indianapolis.

When it comes to Platform devices; quicker speed while loaded with personnel could potentially create a harsh “load” on the aerial when coming to an abrupt stop; for this reason, some platforms either operate slower than ladders, or include “ramping” controls to offer a “softer” start and stop during operations.

Your committee should be able to specify and require reasonable aerial speeds, as they will meet or exceed the NFPA standards. My suggestion is to check out as many aerial trucks as possible; and actually time the devices during evolutions…(you’ll be surprised at the differences)

Which ever device you decide to spend “fly-time” in…remember to always be harnessed. That was also a nice thing to see at the FDIC!

Yes, there are some newer aerial designs that might fit nicely into your existing space. A quick review of typical older 50’ to 65’ “Squirts” on commercial chassis shows that they measure about 32’ to 35’ long. Keeping in mind the need for a full 4-door cab (in place of “canopy” style), some added length may be needed, depending on your man-power needs.

Determining your own Department’s needs is the priority. If the existing “boom” style is working well, modern versions are now available in longer lengths, and can be built on basic custom 4-door cab & chassis’ and still remain in the 35’ length range. (Our company makes a 68’ version).

If “upgrading” to an aerial ladder is more desirable, there are ladder trucks ranging from 60’ (2-section) to 75’ (3-section) models that also fall within this size range. The benefit of using an aerial-ladder device is having a fully rated man-power load (wider ladder sections with higher handrails) which would enhance firefighting or rescue operations when needed…(as opposed to just an “elevated master stream” device).

Which ever choice is made, you can depend on your local fire apparatus dealer or sales rep’ to show you there full line of aerial offerings to determine what would best fit within your Station. Good Luck !
