Abstract
As typically embodied, the inventive ramp system for bridging between structures (e.g., marine vessels) includes a hydraulic elevator device and a ramp unit. The ramp unit includes three adjoining planar members, the ramp member (the main ramp body) being pivotably connected at each end to one of the two platform members. The hydraulic elevator device includes the coaxial combination of a cylinder and a piston, the piston being translatable along and pivotable about the axis. The cylinder-piston combination is secured, axis vertical, to a first structure, with one of the ramp unit's platform members attached atop the piston. In order to position the other (unattached) platform member upon a selected (e.g., horizontal) location of a second structure, the ramp unit is configurable in terms of the attached platform member's height, the ramp unit's horizontal rotation angle, and the respective vertical rotation angles of the ramp unit's two pivotable connections.
