The invention provides a ramp system for transporting objects from a lower site to an upper site and vice versa while keeping the object in a generally horizontal, or upright, orientation when the object is moved up a variable incline. Two rails are provided between the upper and lower site, and a carriage is provided with wheels to allow it to move along the rails. A plurality of cables extend from the carriage to the upper site and to the lower site, the cables passing through pulleys affixed to the carriage, in an arrangement which causes the front portion of the carriage to be cantilevered over the rails, thus keeping a horizontal orientation notwithstanding the incline of the ramp. In a preferred embodiment, the system is implemented in a marine environment between a floating dock and a fixed pier.
