摘要
A port ramp for access to a ship, having a first end supported by a quay and a second end rigidly supported by a float, the float being anchored by blocks to the bottom by a connection of selectively adjustable length, the maximum buoyancy of the float being at least equal to the weight of the ramp added to the maximum load thereon, so that, when the float is submerged, the height of the ramp above the surface is independent of the load on the ramp.
