Self Aligning Rotator

Self aligning rotator structure like the trunnion brackets that support the wheels mechanically align themselves if shifting from 1 diameter to another, no manual alteration at all is required.

Each segment supports the boat / Job on four factors ensuring greater grip, and on machines of 3 T to 500 T ability and upward 50 metric tonnes all four wheels of the driveway segment are positively pushed. This four stage suspension is an extra advantage when on managing thin walled vessels.

Both leading wheels of the driveway section incorporate clutches that are loosened before loading the boat and the upper wheels can rotate freely when the boat is loaded; hence regardless of weight in the event the boat is reduced centrally involving the frames, or to a single wheel only, no harm could be sustained by the transmission.
