guide wheels 55 mounted on the inner edge structure 57 of the rotating platform run against a stationery circular guide rail 59 embedded in the upper edge of the circular center concrete structure 61 as shown in fig2 the bridge 28 provides an elevated walkway over the platform to allow passengers on the platform to walk or be carried under the bridge without interference the peripheral edge 34 of the platform 32 has a contact perimeter of vertically mounted wooden slats or continuous steel plates 58 which cooperate with a series of vertically disposal wooden slats 60 on the conveyer 36 to oppositely engage the raft 12 wedged therebetween the raft 12 is fabricated with an outer pneumatic floatation bladder 64 that emcompasses a plastic shell 68 the shell 68 has a plurality of seats 70 for a designated number of passengers here six by appropriate rescaling to the terminal particularly the distance between platform and conveyer larger or smaller rafts can be accomodated it is naturally understood that the operating mechanisms here described can be applied to vehicles of other configuration or modes of transport for example wheeled vehicles the wooden slats or steel plates on the platform and wooden slats on the conveyer provide a suitable contact surface for the pneumatic bladder compressing the bladder slightly to generate the necessary traction for transport of the raft the raft is thereby transported by the joint action of both the conveyer and platform the slats 60 on the arcuate conveyer are mounted to upper and lower drive chains 62 shown in greater detail in fig3 referring to the cross sectional view of fig3 a typical chain support stanchion 72 is shown a.
