FIELD: mechanical engineering. SUBSTANCE: device has bed 1, at least one rail which has head 3, at least one vehicle 4 which has wheels 5 which are in contact to rail. In addition it has driving engine and string 7 which has separate wires or strips and is extended by force N1 which conforms to equations $$$, where N2 is tensile force for string, Q is weight of vehicle. String 7 is located on alternating rigid and moving supports. Rail head 3 is connected to string 7 by means of insertion 10 which has varying height which is increased in direction towards middle part between supports. EFFECT: increased functional capabilities. 64 cl, 29 dwg
