A vehicle including a body and an aerial device operable to rotate, extend, and retract relative to the body. The vehicle further includes a control panel, an electronic display, a computer control system, and an aerial elevation sensor that senses an elevation of the aerial device, wherein the computer control system receives a piece of data corresponding with the elevation and generates a graphical representation of the current operating ability of the aerial device based on the elevation that is displayed on the electronic display of the control panel.

A vehicle includes a chassis defining a longitudinal axis, a cab coupled to the chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, a body assembly coupled to the chassis, and a ladder assembly. The body assembly defines a recess that includes a plurality of angled portions. The plurality of angled portions extend laterally outward at a downward angle away from the longitudinal axis. The ladder assembly has a proximal end disposed within the recess. The plurality of angled portions at least partially facilitate the ladder assembly in traveling through at least one of a sweep angle range or a depression angle range.

An electronic display for an aerial device is provided. The electronic display replaces a traditional load chart including the operational parameters of the aerial device being used. The electronic display electrically connected with a computer control system connected to a sensor for collecting at least one piece of data relating to the operational parameters of the aerial device. The computer control system calculating the current operational parameter of the aerial device based on the at least one piece of data collected by the sensor and updating the operational parameters of the aerial device and displaying a graphical representation of the updated operational parameters on the electronic display.

Various vehicle systems are proposed for accessing and utilizing vehicle cargo spaces on vehicles equipped with a tailgate assembly. The vehicle systems may include deployable and/or rotatable stairgate systems, deployable step systems, etc. designed for the accessing the vehicle cargo spaces. The proposed systems may include various deployment mechanisms that enable the stairgate/step systems to slide, pivot, rotate, swing, and/or otherwise adjust for providing ease of access and increased flexibility when stepping up to access the vehicle cargo space.

A fire apparatus includes a chassis, a body assembly coupled to the chassis, a front cabin coupled to a front end of the chassis forward of the body assembly, a front axle coupled to the front end of the chassis, a rear axle coupled to a rear end of the chassis, and a ladder assembly having a proximal end coupled to the chassis. The body assembly includes one or more angled portions. The one or more angled portions at least partially facilitate the ladder assembly in traveling through at least one of a sweep angle range or a depression angle range.

A fire apparatus includes a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, a ladder assembly coupled to the chassis, and a stability system. The stability system includes at least one of (i) a front downrigger coupled to the chassis or (ii) a rear downrigger coupled the chassis, and an outrigger coupled to the chassis. The at least one of (i) the front downrigger or (ii) the rear downrigger and the outrigger are extendable and retractable to facilitate leaning the fire apparatus at least two degrees relative to a ground surface while maintaining full operational capability of the ladder assembly.

A fire apparatus includes a chassis, a body assembly, a front cabin, a front axle, at least one rear axle, a ladder assembly having a proximal end that is coupled to the chassis between the front axle and the at least one rear axle, a stability system, and a controller. The stability system includes a pair of front downriggers, a pair of rear downriggers, and an outrigger assembly coupled to the chassis between the front axle and the at least one rear axle. The front and rear downriggers are selectively extendable to engage a ground surface. The outrigger assembly includes a pair of outriggers that are selectively extendable from the body assembly to engage the ground surface. The controller is configured to facilitate controlling extension and retraction of the front downriggers, the rear downriggers, and the outriggers to lean the fire apparatus.

A vehicle including an aerial device movable from a first position to a second position. A computer control system includes a sensor that detects an operational parameter of the aerial device when the aerial device is in the first and second positions. The sensor outputs first and second signals for the operational parameter when the aerial device is in the first and second positions. When the aerial device is in the first position, the computer control system generates a first graphical representation of the current operating ability of the aerial device in response to the first signal and displays the first graphical representation on the electronic display. When the aerial device is in the second position, the computer control system generates a second graphical representation of the current operating ability of the aerial device in response to the second signal and displays the second graphical representation on the electronic display.

A fire apparatus includes a chassis, a body assembly coupled to the chassis, a front cabin coupled to a front end of the chassis forward of the body assembly, a front axle coupled to the front end of the chassis, at least one rear axle coupled to a rear end of the chassis, and a ladder assembly including at least one extensible ladder section. The ladder assembly has a proximal end that is coupled to the chassis rearward of the front cabin and between the front axle and the at least one rear axle. The ladder assembly is operable through a sweep angle greater than fifteen degrees while at a depression angle greater than eight degrees.
