The Roseville (MN) Fire Department, situated north of the twin Minnesota cities of Minneapolis and St. Paul, had to replace a 1990 custom pumper on a Volvo chassis but wanted a new pumper that was shorter, had a larger water tank, and had more horsepower from its diesel engine.
Neil Sjostrom, Roseville’s battalion chief, says the chief officers turned to the department’s firefighters to determine what the new pumper should have in terms of improvements over the retiring vehicle, eventually coming up with the three major elements needed in the vehicle. “We approached the project with the idea that we were open to all manufacturers,” Sjostrom says. “Each original equipment manufacturer (OEM) brought a chassis to show us, which our firefighters were able to drive and then give us feedback on. Most of the best compliments were about the Rosenbauer and Pierce apparatus. Once that was done, the chiefs met and decided to purchase from Rosenbauer, especially because their factory is just up the road from us.”

Steve Harris, owner of General Safety Fire Apparatus, who sold the pumper to Roseville, says he has a working relationship with the department that goes back to a Rosenbauer rescue-pumper and a Rosenbauer mini rescue truck built on a Ford F-550 chassis. “They wanted a short-wheelbase pumper to make the apparatus more maneuverable,” he says, “but with as large a water tank as we could give them, along with more horsepower and lots of storage.”
The end result was a Rosenbauer CrossFire pumper built on a Commander 4000 R611 chassis that is powered by a 450-horsepower Cummins ISL 9 diesel engine and an Allison 3000 EVS automatic transmission. It has a Rosenbauer N1500 direct-drive 1,500-gallon-per-minute (gpm) power takeoff (PTO) pump, a 750-gallon UPF water tank, a 30-gallon integral foam cell, and an FRC Turbo Foam system. The vehicle’s wheelbase is 190 inches, its overall height is 10 feet 2 inches, and its overall length is 31 feet 11 inches.

Harris says that the pumper’s cab is set up for five firefighters, with three forward-facing seats in the back, a mid-cab personal protective equipment (PPE) cabinet for the driver and officer with access from inside and outside the cab, and interior shelving in the back with access from each side of the cab’s interior.
On the officer’s side above the midship pump is a Little Giant ladder storage compartment, he adds. There are drawer storage areas in the L4 and R4 compartments, with the R4 drawers holding hydraulic rescue tools and equipment instead of being on slide-out trays.
|4 The hosebed on the Rosenbauer-built pumper for the Roseville Fire Department holds 500 feet of five-inch LDH, 600 feet of 2½-inch hose connected to a 100-foot apartment bundle of 1¾-inch hose, and 200 feet of 2½-inch hose preconnected to a fog nozzle.|
Harris points out that an unusual feature of the pumper is a severe duty front bumper with full-width storage area that has a preconnect on the officer’s side for 100 feet of 1¾-inch hose, with the rest of the area set up to store miscellaneous tools like irons, shovels, and other hand tools.
Sjostrom points out that Rosenbauer’s engineers designed a pumper for Roseville that surpassed the department’s expectations. “They were developing the CrossFire project at that time, and we thought it was a good fit for us,” Sjostrom says. “We turned the design process over to the Rosenbauer staff, told them what we needed to do with our truck and what we wanted, and they came back with a pumper that was two feet shorter than our existing pumper with a 750-gallon water tank and is able to carry a lot more equipment than our older pumper.”
|5 Rosenbauer built a hidden-from-view ladder rack into the officer’s side of the Roseville Fire Department pumper. The rack is shown here in its lowered position, which is 40 inches above ground level.|
In an effort to keep firefighters from having to get on the top of the new pumper, the Roseville Fire Department specs eliminated a deck gun on the vehicle. “We didn’t want firefighters to have to be climbing on top of the pumper,” Sjostrom says, “and we didn’t want the pumper to become an exposure in the case of a large tank fire.” Roseville Fire Department has two large tank farm storage facilities on the west side of its 14-square-mile fire protection area.
However, the new Rosenbauer pumper does carry a hosebed of 500 feet of five-inch large diameter hose (LDH), 600 feet of 2½-inch hose connected to a 100-foot apartment bundle of 1¾-inch hose, and 200 feet of 2½-inch hose preconnected to a fog nozzle. Forward of the midship pump panel, the rig has two speedlays, each with 200 feet of 1¾-inch hose, along with the 100 feet of 1¾-inch hose in the front bumper.

“With this new pumper, we were able to reduce the bulk amount of 2½-inch hose that we carry to a manageable amount,” Sjostrom points out. “We have hydrants every 300 feet in our city and are able to get a high volume of water out of them.”
The chief notes that the Roseville station has a relatively short apron out front. “There’s a twisting motion to a vehicle when we are coming out of the station, so we made sure that we went with an air ride cab on the new pumper,” Sjostrom says. “Also, with our PTO pump, we can engage it in both the apparatus cab and at the pump panel. The operator can engage or disengage the pump from either location, which is handled by Rosenbauer’s pressure governor.”

Sjostrom says that the Rosenbauer pumper has all 12-volt LED lighting on it, including Whelen LED warning lighting and FRC Spectra LED scene lighting. The pumper also carries a Harrison 6-kW hydraulic generator. In addition, the rig has a ladder rack that’s hidden from view, according to Harris. “The ladder rack is hidden,” he says. “It’s Rosenbauer’s own design, is hydraulic, and allows the rack to come down to 40 inches above ground level.”
