Ramp device for ship

Abstract

Abstract PURPOSE:To set an effective width of a ramp for passage to be the entire width of the ramp, by locating a hydraulic cylinder mechanism at a position lower than the ramp. CONSTITUTION:When a rod of the hydraulic cylinder mechanism 10 is stretched, a flap body 9 is rotated leftward with a movably fitting part 8 as a fulcrum, and simultaneously the mechanism 10 is also rotated with a fitting part of a ship's bottom part 5' as a center. When the flap body 9 reaches an upright condition, an opening 11 of a main body 7 of the ramp accords to an opening 12 provided on the side of the flap body 9, and a pin 14 is inserted therein by driving a cylinder rod 15 of a locking mechanism, whereby the main body 7 of the ramp and the flap body 9 are integrated with each other. Thereafter, when the rod of the mechanism 10 is contracted, the flap body 9 is rotated to the original position. Concurrently with this constitution, the main body 7 of the ramp is raised, and is stored in the ship's hull in an uprigh state.
