    摘要: An electrified fire fighting vehicle includes a chassis having a pair of frame rails, a cab coupled to the chassis, a body coupled to the chassis rearward of the cab, an electric motor coupled to the chassis between the pair of frame rails, an energy storage system positioned between the cab and the body, and a shield. The energy storage system includes a power cable coupled to the electric motor. The shield is positioned (a) between the pair of frame rails and (b) at least partially along and around a motor housing of the electric motor such that the power cable is disposed between the motor housing and the shield.

    摘要: An electrified fire fighting vehicle includes a chassis, a cab coupled to the chassis, a body coupled to the chassis rearward of the cab, an axle coupled to the chassis, a battery pack having a maximum capacity, a driveline coupled to the axle, and a controller. The driveline includes an electric motor coupled to the battery pack. The controller is configured to prevent charging the battery pack beyond a charge threshold to maintain an amount of storage capacity between the charge threshold and the maximum capacity to accommodate energy generated during one or more regenerative braking events and permit charging the battery pack beyond the charge threshold up to an overcharge threshold in response to receiving an override command or a certain mode selection. The overcharge threshold is greater than the charge threshold but less than the maximum capacity.

    摘要: A lift device includes a lift assembly, a platform, and a controller. The lift assembly is configured to be driven to increase or decrease in length by extension and retraction of one or more actuators. The platform is coupled at an upper end of the lift assembly. The controller is configured to receive a value of a pitch angle and a roll angle of the lift device from an orientation sensor. The controller is further configured to determine a maximum allowable elevation of the platform based on at least one of the value of the roll angle and the value of the pitch angle of the lift device. The controller is further configured to limit operation of the lift assembly based on the maximum allowable elevation of the platform.

    摘要: A deck for a lift device includes a floor that defines a surface, a pair of side portions, multiple wear pads, multiple pins, and a hand rail. The pair of side portions are positioned on opposite sides of the floor. Each of the pair of side portions is configured to define a channel configured to receive a middle rail of a platform of the lift device. At least one wear pad is positioned within each of the channels and abuts a top of the middle rail. The pins are removably inserted into openings of the side portions. The pins are configured to extend past a bottom surface of the middle rail to limit removal of the deck from the middle rail. The hand rail extends from a rear portion of the deck.
