The ramp is attached to a floating pontoon body (15) by a fixture (20) which is pivotable for the change in height of the sea level. The ramp is also attached to the quayside (12) which also pivots and has a drive on ramp (16). The ramp height above the sea level can be adjusted by hydraulics (18) which are connected to the outer and inner ramps (11b, 11a). This allows the ramp to unload or load various levels of a boat. |
