摘要
A self stabilizing elevator float having a float body divided into a series of ballast tanks which are bailed or flooded to raise or lower the float body. A first pair of vertically displaceable towers are arranged at one end of the float. A second pair of towers at the opposite end of the float are displaced sufficiently transverse from the float so that the first and second pair of towers imparts longitudinal and transverse stability to the float.
