Abstract

The platform is designed for transportation of people and palletized or bulk materials on rails between two sites. It has simplified, reliable, technological and cheap structure. Sites (11 and 12) comprise rails (1) for wheels (6) of two platform cabins (2), which, by means of chains (4) are suspended on a double guiding wheel (3) with a reducer (8), which lifts and drops them to the respective sites. In an embodiment of execution, the step-like platform with a parapet (2) is connected to a winch (23) with a brake (9). Parallel to the inclined profiles (5) there is a rail (24) for roller support (25). Winch (23) drops the platform on automatic brake (9), or, respectively, by reversing the motor (10) In another embodiment of execution, the road (1, 24) and floor (18) are horizontal, base (21) connecting the connected chain (4) and rope (22), going around a stretching pulley (26). The guiding wheel (3) in case of red traffic lights moves the platform between pavements (11, 12 and 12, 11). In a third embodiment, platforms (2) are connected by means of chain (4) and rope (22).Wheel (3) drives them opposite along horizontal or inclined rails (1, 24). In a fourth embodiment, the two platforms (2) are connected by chains (4), going around double wheel (3) of brake (9). In a fifth embodiment driving of platforms (2) is like a brake rope, or endless rope, respectively. In a sixth embodiment, the inclined roar (1) is for a roller (2, 33) which is connected to a windlass over a sauna (35) and end with a jumping board (11). In other embodiments the platform is an elevator, the rope of which goes around a guiding pulley (27), or is a bicycle (41) with a starting wheel (42) or a yoke (2) for palletized cargoes. In still another embodiment the platform can be an elevator (2) with a starting wheel (42), or be a bicycle swing for two (2, 33) with U-shaped rail (1), or be a bottom (2, 52) of a hopper, or be a bottom (2, 52) of a chassis (57). 16 claims, 34 figures
