Abstract: An aerial device for operating on energized powerlines is disclosed. The aerial device may have a boom assembly with a lower, electrically non-insulating boom section coupled to an upper, electrically insulating boom section. The lower and upper boom sections may be coupled by a pinned connection that utilizes structural collars and structural pins to handle loads applied to the upper boom section. The upper boom section may articulate relative to the lower boom section using a 4-bar mechanism employing a split pivot pin that enables a greater range of motion for the articulation. A modular sled that can be coupled to various boom assemblies is also disclosed.

Abstract: A modular subbase may comprise an upper surface, a longitudinal supporting structure coupled to the upper surface, one or more outrigger boxes coupled to the longitudinal supporting structure and the upper surface. The longitudinal supporting structure may comprise a wide sheet of metal comprising two upwardly-facing arms and a medial section adapted to be lightweight and to provide structural support to the upper surface. The longitudinal supporting structure and upper surface may comprise struts configured to prevent buckling of the medial section and the upper surface The modular subbase may be configured to couple to one or more modular bodies. The modular bodies may couple directly to the upper surface. A boom-arm pedestal for operating a boom-arm may be integrated into the upper surface and may be structurally supported by the modular subbase.

Abstract: A track roller assembly for supporting telescoping boom sections of aerial devices. The track roller assembly is positioned in an interior channel of a hollow first boom section. The track roller assembly supports a majority of the weight of a second boom section and facilitates the second boom section telescoping in and out of the first boom section. The track roller assembly comprises a bracket to securely couple the track roller assembly to the interior channel of the first boom section, a plurality of rollers rotatably connected to the bracket, and a continuous track engaging the plurality of rollers on an interior surface and adjacent to the second boom section on an exterior surface.

Abstract: A pin with threads that extend along a portion of a stem of the pin interact with framing members as the pin is driven through the framing members. The interaction of the threads with the framing members cause the pin to rotate as the threads pass through the framing members and fastens the framing members together. A pin with curved wings that extend along a portion of a stem of the pin interact with framing members as the pin is driven through the framing members. The interaction of the wings with the framing members cause the pin to rotate as the wings pass through the framing members and fastens the framing members together.

Abstract: A harpoon nail having two or more sets of teeth on opposite sides of fingers that deform while penetrating the framing members. The teeth engage with a bottom surface to fasten the framing members together. A piercing nail having sets of teeth on two edges penetrates through framing members and the teeth engage with a bottom surface to fasten the framing members together. A piercing nail with a spring member that deforms as the nail penetrates through framing members engages with a bottom surface to fasten the framing members together. A self-locking nail having two members that move relative to one another when penetrating through framing members fastens the framing members together.

Abstract: A fastening tool including a housing, a magazine connected to the housing for storing a fastener, a driving mechanism disposed within the housing for driving the fastener into a workpiece, a trigger assembly pivotally attached to the housing for activating the driving mechanism, the trigger assembly comprising a main trigger, pivotally attached to the housing and a supplemental trigger pivotally attached to the main trigger; and a contact trip assembly comprising an upper contact trip contacting the supplemental trigger, a lower contact trip connected to the upper contact trip, wherein the upper and lower contact trips have teeth that mesh together for locking the upper and lower contact trips.
