  • Publication number: 20200002955
    Abstract: Methods, systems and apparatuses for providing high electrical resistance for an upper control assembly (including control handles) of an aerial lift are provided through an isolation member that is integral to the upper control assembly and interposed between fluid lines in the control assembly and a set of fluid conduits that extend from the control assembly towards other portions of the aerial lift. The isolation member is a dielectric element that comprises a manifold that is made of material that is substantially electrically non-conductive, and that has a plurality of through-holes or hoses configured to allow hydraulic fluid to flow through the isolation member into and out of the fluid lines and conduits. These methods, systems and apparatuses are preferably used in upper control assemblies of aerial platforms that can carry one or more operators in order to prevent such operators from electrocution when controlling the lift.

  • Patent number: 5870966
    Abstract: A folding pontoon boat to be typically used by one person. Consisting of a semi flat midsection which pivots about it's center axis. A plurality of pontoons are attached to the starboard and port sides of the midsection. Said pontoons pivot beneath the midsection and the front pontoons fold on top of the aft pontoons when the midsection is folded. The boat contains an elevated seat support assembly which automatically collapses into the midsection as the midsection is folded. In the stowed position wheels extend below the aft pontoons to permit maneuverability over land. As an alternative storage means the pontoons may be disconnected from the midsection by removing the pontoon pivot pins. Additional seating can be easily attached to the current invention. Additionally two or more of the current invention can be attached together to form a larger boat.
