A vehicle body. The vehicle body comprises a fluid transfer system integrated within the vehicle body. The fluid transfer system comprises a fluid evacuation system comprising a first fluid storage container, a fluid refill system comprising a second fluid storage container, a sensing system coupled to the fluid evacuation system and the fluid refill system, and a control circuit coupled to the sensing system, the fluid evacuation system and the fluid refill system. The control circuit is configured to (1) determine an amount of a first fluid in the first fluid storage container based on a first signal from the sensing system, and (2) determine an amount of a second fluid in the second fluid storage container based on a second signal from the sensing system.

A tanker truck offloading system and method. The tanker truck offloading system includes a manifold in fluid communication with a tank and a plurality of tanker truck offloading stations, a tanker truck coupling at an open end of the manifold at each of the plurality of tanker truck offloading stations, and an air separator in fluid communication with the manifold.

An electrified fire fighting vehicle includes a battery pack, an electromagnetic device, an engine, and a controller. The controller is configured to monitor a state-of-charge of the battery pack, operate the electromagnetic device using stored energy in the battery pack to provide a performance condition including (i) accelerating the electrified fire fighting vehicle to a driving speed of at least 50 miles-per-hour in an acceleration time and (ii) maintaining or exceeding the driving speed for a period of time, and start and operate the engine in response to a start condition to facilitate reserving sufficient stored energy in the battery pack such that the state-of-charge is maintained above a minimum state-of-charge threshold that is sufficient to facilitate the performance condition. The acceleration time is 30 second or less. An aggregate of the acceleration time and the period of time is at least 3 minutes.

A tractor mountable auxiliary tank system includes a frame that is secured to a body of the tractor such that an axle of the tractor extends below a top side of the frame. A tank for holding a quantity of liquid has a top wall, a bottom wall, and a perimeter wall extending between the top and bottom walls. The perimeter wall includes a front wall, a rear wall, a first lateral wall and a second lateral wall. The bottom wall has a shape conforming to a top side of the frame such that the tank is stabilized by the frame. The tank is positioned between the body and a ground engagement member engaged with the axle. A coupling member releasably couples the tank to the frame.

Systems, methods and apparatus are provided for liquid product delivery. In some embodiments a conduit assembly disposed partly beneath a deck or platform is fluidly coupled to a reel assembly via a rotary fluid coupler.

An emergency response barrier is shown and described, the barrier having a cab and engine for propelling the barrier; a frame with reinforcing bracing; two axles coupled to the frame with wheels attached thereto; wherein the frame is covered with a substantially planar skin that extends along the right and left sides of the frame, from a top of the frame down to a lower edge and covers a majority of the wheels on each side of the barrier; an impact attenuator coupling on the frame, having a vertical pin received in a bore disposed on an impact attenuator, and configured for rotation about the vertical axis of the pin; and a hydraulic cylinder connected between the frame and the impact attenuator, wherein retraction and extension of the hydraulic cylinder moves the impact attenuator through an arc of rotation about the vertical pin.

An agricultural product delivery applicator for delivering particulate product to a field. The applicator comprises a bin to hold the product, a pneumatic conveying system to provide an airflow, a metering system operably connected between the supply compartment and the pneumatic conveying system, and a rail system. The metering system meters product with the airflow to result in a mixed flow of airflow and product. The rail system includes first and second foldable rails.

A fluid-driven hatch for a bulk material container includes a cover is opened by a fluid-driven cover actuator and secured by a fluid-driven lock actuator. A fluid conduit connects both the fluid-driven cover actuator and the fluid-driven lock actuator to a pressurized fluid source. Pressurized fluid is selectively supplied to the fluid conduit such that the fluid-driven lock actuator is actuated at a first pressure to unlock the cover, and the fluid-driven cover actuator is actuated moments later at a second, higher pressure to open the cover.

A tanker truck offloading manifold method. The tanker truck offloading method includes detecting a tanker truck in at least one of a plurality of offloading stations, energizing a blower having an inlet duct coupled to a tank receiving fluid from the plurality of offloading stations, the blower to draw gasses from the tank when at least one tanker truck is offloading at least one of the plurality of offloading stations, de-energizing the blower when no tanker truck is offloading at any of the plurality of offloading stations, energizing a pump having an inlet coupled to the tank when the tank level is above a predetermined high level, and de-energizing the pump when the tank level is below a predetermined low level.
