The 2013 trade show season is underway, and apparatus pundits are rushing to print the latest and greatest innovations in the fire truck world. Recent articles heap praise on those manufacturers who can cram ten pounds of fire truck into a five-pound space. Equal admiration is bestowed on fire departments that spec multifunction apparatus to the next highest, longest, widest, heaviest, and most expensive level. It happens every year. You seldom see an article complimenting a simple straightforward single-purpose apparatus design. You never see a follow-up commentary on a rig that's been in service for a couple of years: "Hey, Chief, how's that design working for you? Would you change anything? Buy one like it again?"
Apparatus commentators are seldom explicit in expressing personal likes or dislikes. And, they never disagree, challenge, or take issue with a rig's design, accoutrements, or intended function. This article will.
Readers, please take note: This is not a criticism of the manufacturer, the fire department, or how either operates. It's irrelevant who wrote the specs, who built it, who bought it, and what it's made out of. It's an outsider's personal analysis of some features of a pumper from operational and spec-writing perspectives. Maybe it'll help the next department when writing specifications for a new rig.
Engine 41 was designed as a primary attack pumper whose sole function is to establish a water supply and put wet stuff on the red stuff. It was not designed to serve double duty as a rescue, tanker, squad, service, salvage, or ladder company. You can't get much more basic than that. Its response area can be characterized as an older congested northeastern municipality with narrow streets, narrower alleys, and approximately 13,000 residents packed into fewer than two square miles.
Basic Design
The truck replaced an older pumper of similar size with open jump seats. The new rig, less than 29 feet long, has a short 168-inch wheelbase-only six inches longer than its predecessor. It has a six-person custom cab, 500-gallon tank, 2,000-gallon-per-minute (gpm) rated pump, preconnected truck-mounted monitor, and traditional body style with high left-side and low right-side compartments. At first glance, it looks like a ho-hum "plain Jane" vehicle. A closer look shows it's a compact, hard-hitting, versatile, and functional piece of apparatus well suited to fulfill its intended mission.
Main Hosebed
When delivered, the main hosebed was loaded with 1,000 feet of five-inch large-diameter hose (LDH) and 1,200 feet of three-inch double-jacketed rubber-lined (DJRL) hose. A 600-foot dead load of 2½-inch DJRL was carried beneath a 2½-inch preconnect. There's more than 150 cubic feet of space in the bed-five times the minimum required by National Fire Protection Association (NFPA) 1901, Standard for Automotive Fire Apparatus-for 2½-inch or larger fire hose. It easily accommodates the aforementioned hose plus four rear preconnects. And, it's not full yet.
There is no issue with the quantity and size of supply line carried. That's the department's business. I favor large hosebed capacities. However, it could have been configured to allow a walkway to facilitate loading. A walkway in the main bed makes the troops' lives easy. Easy is good.
Everyone likes low hosebeds. An "L" shaped tank keeps the bed less than four feet from the tailboard. And, it's almost 40 inches deep. It looks good, but looks can be deceiving. Most firefighters have about a three-foot wing span. How easy (or hard) will it be for firefighters on top of the rig to lean or reach over the top of a couple of hosebed dividers and access the bottom of the bed? That could be problematic if you have a couple of short-armed firefighters trying to load single-stacked hose into a 40-inch-deep bed.
