Techniques control attachment of equipment to a vehicle deck. Such techniques involve positioning an equipment base that serves as a base of the equipment on the vehicle deck. Such techniques further involve extending a latching mechanism of the equipment base to provide a first latching width that captures the equipment base between a set of deck clamps and a deck jamb mounted to the vehicle deck to fasten the equipment to the vehicle deck. Such techniques further involve contracting the latching mechanism to provide the equipment base with a second latching width that enables the equipment base to escape from the set of deck clamps and the deck jamb mounted to the vehicle deck to unfasten the equipment from the vehicle deck.

A vehicle includes a floor plate defining a front and a back of the vehicle, wall sections to receive vehicle loading and transfer the vehicle loading to the floor plate, and a fluid delivery assembly supported by the floor plate. The fluid delivery assembly includes an intake manifold that resides at the back, an outlet that resides at the front, and a set of lateral conduits extending between the intake manifold and the outlet to laterally convey fluid entering the intake manifold from a fluid source to the outlet for delivery to a fluid target. Accordingly, the back may connect to the fluid source and the front may deliver the fluid thus keeping the vehicle sides and top available for other uses. Moreover, the low isolated placement of the fluid delivery assembly safeguards the fluid delivery assembly and provides a low center of gravity for vehicle stability.

An overridable failsafe brake apparatus for a vehicle is provided. The overridable failsafe brake apparatus includes (a) a lever accessible from outside the vehicle, the lever being operable at a first position and a second position; (b) a brake; and (c) a spring having a first end coupled to the lever and a second end coupled to the brake. (d) The lever disposed in the first position is configured to induce tension in the spring that enables the brake to be activated, and the lever disposed in the second position is configured to reduce tension in the spring to disable the brake from being engaged. A method of operating an overridable failsafe brake apparatus for a vehicle and a vehicle including an overridable failsafe brake apparatus are also provided.

A control device operates a fire extinguisher system. The system includes a hose having an extinguisher nozzle arranged at the end of the hose for releasing pressurized extinguishing fluid. A conveying pump pressurized conveying of the extinguishing fluid towards the extinguisher nozzle. A first supply line connects the conveying pump to a tank of a fire extinguisher vehicle. A second supply line connects the conveying pump to stationary extinguishing fluid source. A controller is positioned at a distance from the extinguisher nozzle and functions as an operations center. A control line runs along the hose to the nozzle end of the hose. A radio device connected to the control line converts signals from the control line into radio signals and outputting the signals. An operator carried portable radio device receives radio signals output by the radio device. An operator carried display displays information based on the transmitted radio signals.

An unmanned vehicle for initiating a fire extinguishing action, the vehicle having: a vehicle sensor unit for detecting a fire parameter K.sub.F of a vehicle monitoring region, a vehicle communication unit for receiving an instruction signal S.sub.I representing a detected fire, a target location and/or a target region, and a navigation control unit for navigating the vehicle to the target location based on the instruction signal S.sub.I. The vehicle is: configured for detecting the fire parameter K.sub.F in the form of a verification fire parameter K.sub.V of the fire detector monitoring region at the target location by the vehicle sensor unit, configured for determining a verification fire status Z.sub.V by evaluating the verification fire parameter K.sub.V, and designed and/or configured for initiating a fire extinguishing action if the verification fire status Z.sub.V was determined. A system with such a vehicle and a corresponding method are also provided.

A sprinkler head for a sprinkler system including a pipe section, a sealing member provided over a pipe section discharge opening, an abutment connected to the pipe section via a support element, and thermal release element disposed between the abutment and sealing member. A triggering means controls active thermal triggering of the thermal release element and includes an electrical circuit board having a controller, an electric power supply, and an electrical conduction path along the thermal release element. The electrical circuit board is in electrical contact with the sealing member and support element. The abutment and sealing member are electrically connected to the electrical conduction path. Current fed by the power supply through the support element, the abutment, the electric conduction path, and sealing member is produced by means of the controller, causes active heating and thus a triggering of the thermal release element.

A relatively small fire apparatus vehicle, which may have a single rear axle, is provided that includes a high-flow articulated water tower that delivers water at a rate of up to 1500 GPM (gallons per minute). The high-flow articulated water tower includes a water splitter that divides a water flow from a pump system into a pair of water flow path segments delivered through a pair of lower tower arm water pipes. The water flow path segments may be recombined in a water stem knuckle at a joint between the lower tower arm and an upper tower arm of the articulated water tower that is delivered as a combined flow through an upper tower arm water pipe and out a delivery nozzle.

An aerial firefighting system (AFS) is provided that is more effective and produced at lower cost than existing firefighting systems currently in operation. The AFS may use at least one wing mounted tank having an interior volume and attached to at least one of aircraft wings, the volume of the tank is adapted to hold a fire retardant and includes a nozzle in fluid communication with the volume. The wing mounted tanks are modified with a controllable flow nozzle at the end of each firefighting tank to ensure correct coverage and pinpoint accuracy of aerial drops. An auxiliary tank held within the cargo hold (feed cargo tank) is in fluid communication with the wing mounted tanks. The auxiliary tank may be a palletized tank that can be loaded on to the plane as needed. The auxiliary tank may hold between 4000-5000 gallons so as to allow an aerial tanker to make additional drops without having to land for additional fire retardant liquids.

A device for generating a jet of two-phase fluid, comprising a nozzle having a main duct that is fed with a pressurized gaseous fluid and opens into a mixing chamber, and at least one secondary duct that is fed by at least one pressurized fluid and opens into the mixing chamber in a direction forming a non-zero angle with the axis of the main duct. The mixing chamber has a convergent-divergent cylindrical wall having a constriction defining an opening in the plane perpendicular to the axis of the main duct. The convergent part of the wall has a frustoconical region in the continuation of the axis of the at least one secondary duct so as to form a fragmentation chamber for the liquid phase.

A modular system is disclosed for handheld nozzles to facilitate distinguishing various nozzles in terms of nozzle type, owner, or type of fluid. Modular attachments are removably coupled to handles of the nozzles to provide the distinguishing characteristics. The modular attachment are secured to the handles without the use of mechanical fasteners or adhesives, and, instead, utilize integral mechanical attachment methods. The modular attachments can be made in a variety of colors to enable color-coding the distinguishing characteristics.
