降装置。 Upper and lower outer rings that are fitted into the pedestal penetrating the pontoon and have an inclined guide surface and a horizontal wedge support surface for guiding an upward wedge (to be described later) on a surface facing the pedestal, and that engage the inclined guide surface and the pedestal. A plurality of upward wedges to be removed and wedges on the wedge support surface, which are attached to the outer ring so as to be rotatable up and down, are pressed against the pedestal and cooperate with other wedge cylinders of the same outer ring to reduce the weight of the pedestal. A supporting wedge cylinder, a plurality of main cylinders that connect the upper and lower two outer rings to raise and lower the pontoon and the pedestal,
This elevating device is characterized by being composed of a plurality of tension rods that penetrate through two upper and lower outer rings, have a lower part attached to a pontoon, and an upper part provided with a locking part for transmitting the load of the pontoon to the pillar when the pontoon is raised or lowered.
