Abstract: A vehicle includes a chassis, an implement assembly coupled to the chassis, a stability system coupled to the chassis, and a control system. The stability system includes extendable components that selectively engage a ground surface. The control system is configured to control the stability system to level the vehicle and enable the stability system to lean the vehicle when an operational capability of the implement assembly is at a limit thereof while the vehicle is level to effectively improve the operational capability relative to when the vehicle is level.

Abstract: A fire apparatus includes a chassis and a ladder assembly coupled to the chassis. The ladder assembly includes a first ladder section, a second ladder section slidably coupled to the first ladder section, a first support pivotably coupled to the first ladder section, and a second support fixedly coupled to the first ladder section. The first support and the second support are each configured to limit vertical movement of the second ladder section relative to the first ladder section.

Abstract: A fire apparatus includes a chassis, axles coupled to the chassis, a turntable rotatably coupled to the chassis, and an aerial ladder assembly pivotably coupled the turntable. The aerial ladder assembly includes a first ladder section extending longitudinally, a second ladder section extending longitudinally, and a support slidably coupling the second ladder section to the first ladder section such that the first ladder section supports the second ladder section. The support facilitates longitudinal movement of the second ladder section relative to the first ladder section between an extended position and a retracted position. The support is pivotably coupled to the first ladder section.

Abstract: A stabilizer for a vehicle includes an actuator assembly configured to be coupled to a chassis of the vehicle and configured to lift the vehicle. The actuator assembly is coupled to a ground pad having a bottom surface configured to engage a support surface below the chassis when the actuator assembly lifts the vehicle. An alignment member is configured to be coupled the chassis. The alignment member is configured to limit rotation of the ground pad. The actuator assembly is configured to move a surface of the ground pad into engagement with the alignment member to cause rotation of the ground pad relative to the chassis.

Abstract: A mid-mount fire apparatus includes a chassis, a body assembly coupled to the chassis, a front cabin coupled to the chassis forward of the body assembly, a front axle coupled to the chassis, a rear axle coupled to the chassis, and a ladder assembly having a proximal end that is coupled to the chassis rearward of the front cabin and between the front axle and the rear axle. The ladder assembly includes a plurality of ladder sections. The ladder assembly is extensible to a horizontal reach of at least 88 feet. A distal end of the ladder assembly does not extend beyond the rear end of the body assembly when fully retracted.

Abstract: 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.

Abstract: A folding staircase for use in a door opening having a threshold. The folding staircase has a pair of stringers that have an upper end and a lower end that is adapted for contacting a ground surface. The stringers are spanned by at least one tread. A hinge is connected to a floor near the door opening and a threshold plate pivotally connected thereto is movable between a use position and a stowed position. The staircase may be provided with a lifting mechanism that biases the staircase and threshold plate toward their stowed positions. The lifting device provides a variable force that provides more rotational force when the staircase would require a user to bear more of its weight and less force when less of the weight of the staircase would be borne by a user.

Abstract: A portable step device is disclosed herein. The portable step device includes a step support surface with a top-side, the step support surface further having a surface-covering affixed to the top-side. The device also features a support rod having a length, a step-end, a base-end, a front-side and a back-side, where the support rod is fixed to the bottom-side of the step support surface and configured to elevate the step support surface away from a terrain. In addition, the device includes a base support surface having a support-rod side and a ground-side to provide stability for bracing the support rod and the step support surface on the terrain.
