Abstract: Systems and methods for fire suppression systems are disclosed. In one embodiment, the fire suppression system comprises a water supply system, a foam concentrate supply system, and a foam concentrate recovery system. The water supply system includes a water pump and a water supply line. The foam concentrate supply system includes a foam pump and a foam concentrate supply line, the foam concentrate supply line fluidly connected with the water supply system to facilitate mixing foam concentrate provided by the foam concentrate supply system with water provided by the water supply system. The foam concentrate recovery system includes a recovery pump fluidly connectable with the foam concentrate supply system to facilitate the extraction of foam concentrate from at least a portion of the foam concentrate supply system. The system and method can also include circulating foam concentrate to promote mixing and hinder the congealment of foam concentrate.

Abstract: Systems and methods for determining the accuracy of a foam addition system on a firefighting vehicle are disclosed. The methods may include measuring the amount of a test water stream flowing through a foam metering device.

Abstract: An telescopic ladder for a vehicle. The telescopic ladder comprises a first ladder section and a second ladder section, with each ladder section comprising a front portion and a rear portion and each including opposing sides extending from the front portion to the rear portion. The second ladder section is configured to telescopically extend from the first ladder section. The telescopic ladder further includes an extension support for facilitating the extension of the second ladder section from the first ladder section. The extension support includes at least one front roller assembly positioned adjacent to a front portion of the first ladder section, at least one pair of side roller assemblies positioned on the sides of the first ladder section, and at least one pair of cam-follower assemblies positioned on the sides of the second ladder section adjacent to the rear portion of the second ladder section.
