Abstract
PURPOSE: To provide a ramp raising, lowering and supporting apparatus, which is arranged to be retractable at the back of rampway when it is not in use, whereby it is enabled to make an efficient use of the space in the ship and to improve efficiency of cargo handling operation.
CONSTITUTION: Base end of rampway 12 is connected to the upper deck in pivotally movable manner by means of hinge, whereas its top end is so arranged that it is connected to the lower deck 11 and also detached therefrom by means of an inclined surface. A ramp raising, lowering and supporting apparatus 15 is provided on the back surface of rampway 12 substantially at the middle portion of the same. With such an arrangement, rampway 12 can be supported by drawing out a pin for connecting bracket 22, extending link cylinder 19 and shifting the base end A2 of ramp raising and lowering cylinder 16 along guide groove 18, thereby turning the joint of link arm 17 and cylinder 16 in counterclockwise direction, and postitioning the top 24 of rod in a sliding recess 23 formed in lower deck 11.
