Scaffold Supported Internally On Shaft Patents (Class 182/128)
  • Patent number: 9493957
    Abstract: A plank (10) used to construct a platform such as a catwalk (C3, C4) extending about the exterior or interior of a building (B) includes first and second generally horizontal sections (12, 22). The second generally horizontal section of the plank extends from one side of the first section. During construction of the platform, the first section of one plank overlaps the second section of an adjacent plank. A third generally vertical section (52) of the plank extends generally perpendicularly from one side of the second section and includes lips (58, 60) at its inner and outer ends for attaching the plank to toe boards (40, 44) to secure the plank to the frames. When installed, the planks extend from a side of the building. The resulting catwalk extends either in a straight line, or is curved, depending upon the amount of overlap the first and second sections of the respective planks.

  • Patent number: 9382719
    Abstract: This platform provides access to a hydraulic machine via a suction tube. This hydraulic machine belongs to an installation for converting hydraulic energy into mechanical or electrical energy, or reciprocally. The platform includes a load-bearing element designed to slide along a longitudinal axis in order to enter an opening in the suction tube, said load-bearing element having an extremity that is designed to be immobilized in the suction tube and floor elements that are placed on the load-bearing element. At least some of the floor elements are articulated with the load-bearing element about axes substantially parallel to the longitudinal axis, while these floor elements can be rotated about these axes between a folded configuration and a deployed configuration and define at least a portion of a floor of the platform.

    Abstract: The invention concerns a working platform assembly for use in the interior of a tower-like building. The object of the present invention is to provide a working platform assembly which can be used in the interior of a tower-like building even if the tower is closed at the top by an upper structure thereon. According to the invention that object is attained by a scissor lattice-like carrier structure and a working platform arranged on the carrier structure. In that respect the invention is based on the that the working platform assembly according to the invention can be adapted to different inside diameters of the tower-like building by virtue of the scissor lattice-like carrier structure and can thus extend completely across the tower cross-section. That makes it possible to work on the platform assembly. The working platform assembly can be released from the tower wall by the scissor lattice-like carrier structure and fixed again in another region of the building of a different cross-section.

Auxiliary support members (33) are releasably affixable to arms (27) of the main structure, and to them are releasably affixable separate personnel support deck units (38). Guard rails (42) can be connected to the deck units. The platform is modular for easy mounting and demounting to the stack. The platform's main support structure (26) can be a long term element of the stack if desired.

  • Patent number: 6186273
    Abstract: Each of a plurality of cargo holds of a bulk carrier vessel has a self-contained staging system lowered into it, from the platform track of which workers operate semi-automatic blasting machines that are mounted onto the platform. The set-up for each vessel also includes, for each hold, a ventilation unit provided on a hatch plug, and a transporter for the staging system. Groups of staging systems are served by on-deck air compressors. Staging systems actually engaging in blasting are served by recycling shot blast units which recycle and supply steel shot. Following blast cleaning, the cleaned surfaces are painted from the platforms.
