CONNECTION PASSAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a connection passage device allowing persons to easily go through mutually between two points where a difference in height is changed. SOLUTION: This connection passage device is provided with a first table 24 and a second table 25 adjacent each other and capable of rising and falling separately and a ramp passage 26 in which a tip part is pivotally supported on the first table 24 so that a terminal part comes close to and leaves a descent position of the first table 24. The first table 24 is raised so as to correspond to the high point, a travel path connecting two points where there is a difference in height is formed by the ramp passage 26 and the first table 24, and the second table 25 is lifted and lowered so as to realize mutual connection of persons and articles between the low point and the first table 24.
