Abstract

PURPOSE: To secure smooth ascent and descent of movable deck by eliminating the partial bending of a main rope and reducing the frictional force generated on the main rope, in a movable-deck lifting apparatus.
CONSTITUTION: A main rope 11 penetrates the upper layer movable decks 4D, 3D, and 2D along the side wall 10a of a hatch, and is bent by the sheave 14 of the movable deck 2D, and guided so as to incline downward between movable decks 2D and 1D to the indide of the ship. Then, the main rope goes upward through sheaves 15 and 19 on the movable deck 1D, and through each sheave 20W24, the top end 11b of the main rope is root-fixed at the root part 25b of the ship body. Thus, the partial bend of the main rope is prevented by this constitution, and in cooperation with the action of an auxiliary rope 18, smooth ascent and descent of the movable deck can be performed. Numeral 12 designates a trolley, W designates a wiper, and 17 designates the guide element of the movable deck.
