Abstract
PURPOSE: To attain the horizontal and inclined postures of the access ramp easily and quickly by expanding or contracting two wires, which are coupled with the front and rear ends of access ramp respectively, by means of a winch at the same time.
CONSTITUTION: When the access ramp 34 is used as an elevator, the cylinders 26, 27 are full extended to make the access ramp horizontal, and the winch 23 is operated. The access ramp can be vertically moved up and down since the wires 21, 22 are expanded or contracted by the same length. Also, when the wharf side cylinder 26 is contracted from the horizontal state, the wires 21, 28, 29 are pulled upwards through the free pulley 24, the front end of the access ramp ascends. On the other hand, when the deck side cylinder 27 is contracted, the rear end of the access ramp ascends. In this way, an arbitrary angle of inclination of the access ramp can be obtained.
