Fire apparatus manufacturers are responding to firefighter requests for better management and placement of hose loads on apparatus, from lower crosslays and hosebeds to slide-out and pull-out trays that make extending hose and reloading it easier.
Crosslays and Speedlays
Jason Witmier, pumper and tanker product manager for KME, says many fire departments are requesting crosslay arrangements that place handlines lower than in the past. "Fire departments want them lower now, so we typically are putting them about 42 inches above the running board, which is about 56 inches off the ground," Witmier says. "That means the hose comes out right at the shoulder so the firefighter can easily take the load."
The disadvantage to a lower crosslay is that firefighters have to repack hose by sliding it into the crosslay area from each side of the vehicle. "You can't get to it from the top," Witmier notes, "so the solution is a slide-out try that is removable. It's usually held in place by a thumb latch and can be taken out of the crosslay area, put on a table or other flat area, and repacked. Some departments also purchase spare trays that they prepack with hose so they are ready to be inserted into the crosslay area after hose is used."
Witmier adds that another potential pitfall with a slide-out crosslay is that sometimes the nozzle is too big to fit into the tray. "We talk to our customers beforehand and determine what kind of nozzle they will use on their crosslays to determine if they can be deployed from each side of the slide-out tray."
Crosslays under the cab extension (the crew area) have become popular with fire departments trying to keep the vehicle's wheelbase short, Witmier points out, but such a location causes a different issue in terms of deployment. "It puts the crosslay at waist height instead of chest height," Witmier says.

Grady North, product manager for E-ONE, believes there are as many hose loads as there are fire departments. "Everyone wants something different so the hose load becomes a customized part of the truck," North says. "With preconnected hoselines, we've seen a 50/50 mix of speedlays and crosslays," North says. "The common configuration for speedlays is vertically stacked on top of each other, which helps tighten up the wheelbase, and we do a lot of double and triple speedlay setups."
Crosslays tend to be higher off the ground, North points out, typically located on top of the pump module with open tops to the beds, compared with speedlays, which are usually in front of the pump module or behind the cab.
Slide-out trays, for both crosslays and speedlays, especially those that can be accessed from each side of the vehicle, have become very popular, North says. "Our trays are fully removable and made out of either aluminum or polypropylene," he says. "A short six-foot length of hose connects to the swivel and then to the hose in the tray."
North notes there is a difference in the preconnect water source for the two types of lays. "The swivel fitting on crosslays comes up from the bottom," he says, "but with a speedlay, the swivel comes from the top of the hose compartment."
And while dual and triple crosslays and speedlays are the most common, North says he's seen much more unusual configurations. "We recently bui
