Abstract: An aerial lift assembly is provided with a base to support the aerial lift assembly upon an underlying support surface. A first link assembly is pivotally connected to the base to pivotally expand and collapse from the base. A first extendable boom assembly is pivotally connected to the first link assembly to pivotally expand and collapse from the first link assembly, and to extend and retract from the first link assembly. A first actuator is in cooperation with the first extendable boom assembly to extend and retract the first extendable boom assembly. A second extendable boom assembly is pivotally connected to the first extendable boom assembly to pivotally expand and collapse from the first extendable boom assembly, and to extend and retract from the first extendable boom assembly. An operator platform is supported by the second extendable boom assembly.

Abstract: An access deck assembly is provided for an aerial lift vehicle mobile platform. A base member defines an upper surface to support an operator, and has first and second guides to cooperate with the platform. A locking mechanism is supported by the base member and retains the access deck to the platform. A method of connecting an access deck assembly to a mobile platform is provided. The access deck assembly is positioned relative to the platform to be above and spaced apart from the platform floor surface, with the base member of the access deck assembly substantially within a perimeter frame of the platform. An access deck assembly has a guide member connected to a base member and configured to connect the base member to the mobile platform and support the base member directly above and spaced apart from the platform floor surface.

Abstract: A land vehicle assembly is provided with a platform for an operator workspace. A control panel is supported upon the platform in electrical communication with the land vehicle. A caution switch is supported upon the platform in electrical communication with the control panel to provide a signal to the control panel indicative of a caution event. A cable is connected to the caution switch to extend across the control panel. The cable is spaced apart from the control panel so that a predetermined force upon the flexible member actuates the caution switch without significantly obstructing the control panel. A manual force upon the flexible member expands the operator workspace. The control panel is programmed to control a mobile operation of the land vehicle, and discontinue the mobile operation of the land vehicle in response to receipt of the caution event signal.

Abstract: A radiator fan shroud (100) is disclosed that is adapted to be attached to a vehicle radiator (96)—for example, the radiator of a Class 8 truck. The fan shroud includes a peripheral cover portion (112) and a ring assembly (102) that encloses the blades of the engine-driven radiator fan (88). The ring assembly may be formed integrally with the peripheral cover portion or may include a separable ring extension (120). The ring assembly includes a plurality of ports (104) defined by vanes (106) at the rearward portion of the ring assembly. The ports are selectively positioned to manage the airflow in the engine compartment, directing the airflow towards selected locations. The vanes may be fluted. The fan shroud may be formed from two or more pieces that cooperatively form the fan shroud, to facilitate installation and maintenance of the fan shroud.
