Claims

[Scope of utility model registration request]

The flat floating body is supported slightly above the water surface via a plurality of cylindrical pillars that penetrate at appropriate intervals along its outer circumference and whose lower ends touch the bottom of the seabed, and each of the pillars is arranged on the floating body and supports each of the pillars. A lower chuck that can be releasably fixed; and an upper chuck that is attached above the lower chuck via a vertical hydraulic cylinder and that can releasably fix the pedestal; In the self-elevating offshore work platform that lifts and lowers the floating body by operating the above-mentioned chucks, the chucks include a ring-shaped machine frame that loosely surrounds the pedestal, and one end of which is pivoted symmetrically to the machine frame and the other end of the machine frame. a pair of left and right horizontal levers that are slightly rotated in a horizontal plane by a horizontal hydraulic cylinder supported by a U;
A pedestal elevating device for a self-elevating offshore work platform characterized by comprising a chuck consisting of a band.
