Abstract: A surrogate foam test system for testing a foam distribution system of a fire fighting vehicle includes a water tank having an outlet coupled to a flush line and a foam storage tank having an outlet coupled to a foam feed line. The water tank provides water through the outlet and the foam storage tank provides a foam fire suppressant. The test system also includes a flush valve coupled to the flush line, where the flush line extends through the flush valve and into the foam feed line at a junction, and a foam valve coupled to the foam feed line before the junction, where the foam feed line extends through the foam valve and accepts the flush line the junction. A flow meter is coupled to the flush line between the flush valve and the junction, where the flow meter is configured to monitor a flow rate of the water within the flush line.

Abstract: An aerial boom assembly includes a first member having a fixed length and comprising first and second ends, the second end configured to be coupled to a mobile base, a second member coupled to the first member at the first end, an extension member slidably coupled to the second member to move between a first position and a second position, and a track having a first end coupled to the second member and a second end coupled to the extension member and configured to guide a dispenser between a first configuration and a second configuration as the extension member is moved between the first position and the second position.

Abstract: A vehicular firefighting system includes a vehicle, a boom pivotally coupled to the vehicle about a horizontal axis and a nozzle pivotally coupled to the boom. In one embodiment, the system includes a linkage having a first end coupled to the nozzle and a second end coupled to the vehicle such that the linkage maintains an orientation of the nozzle as the boom pivots about the horizontal axis. In another embodiment, the boom forms at least one fluid conduit in fluid communication with the nozzle so as to deliver firefighting agent to the nozzle.

Abstract: An aerial boom assembly comprising a first member having a fixed length and comprising first and second ends, the second end being pivotally coupled to a mobile base. The aerial boom assembly comprises a second member pivotally coupled to the first member at the first end, the second member comprising an extension member slidably coupled to the second member along an inner channel of the second member. The first and second members are made from a composite material comprising a reinforcement material in a polymeric matrix.

Abstract: An aerial boom attachment for use with an aerial boom mounted on a vehicle. The aerial boom attachment includes a frame assembly configured to couple to the aerial boom. A drive train assembly is mounted on the frame assembly. The drive train assembly includes two opposing actuators, wherein when one actuator moves in one direction, the other actuator moves in an appropriate opposite direction. A piercing nozzle assembly is coupled to the drive train and configured for motion in one of a vertical and horizontal plane, with the piercing nozzle assembly in fluid communication with a fluid supply.
