Abstract:
A machine comprising:(a) at least two beams disposed between a first station and a second station, each of said at least two beams being fixed with respect to the first station such that there is no horizontal or vertical displacement or rotation about said beams' respective longitudinal axes; (b) support means for each of said at least two beams at the second station, said support means allowing displacement along, and rotations normal to, said beams' respective longitudinal axes; (c) connecting means between said at least two beams that provides constant spacing without substantially increasing torsional stiffness; (d) a transfer shuttle that can traverse the length of said at least two beams thereby allowing roll-on/roll-off equipment transfer without the need for a continuous deck; and (e) means for imparting motion to said transfer shuttle.
