PENDULUM TYPE TRANSPORTATION SYSTEM Russian patent published in 1997 - IPC

FIELD: transport engineering: devices for transportation of loads for short distances and transportation of people under highways or under dangerous ground objects. SUBSTANCE: shuttle type transportation system has stationary guide rail track 3 with gravity acceleration and deceleration sections and vehicle placed on track. Stationary terminal sections 1, 11 are made with radius conjugation with inclined sections and are provided each with one hinge-connected end section 1, 11 with mechanism to change angle of inclination (not shown in drawing) to create additional potential energy for vehicle prior to its moving off Stationary guide track of transportation system in places of change of track gradient with "angle of encounter" of its straight-line section smaller than 176 degrees has additional guides in form of separate rectilinear sections installed in parallel with chord drawn through points of contact of circumference inscribed In above-indicated "angles of encounter" (not shown in drawing). EFFECT: reduced power consumption, improved smoothness of running when transporting people and loads under highways at one and the same or other levels. 4 cl, 23 dwg
