Abstract: 1. A string transport system, comprising at least one monorail fixed on legs in the form of a pre-stressed power unit enclosed in a housing with conjugated working surface for travelling movable units, characterized in that the rail housing is a two stage structure, said stages are separated by a solid, perforated or built of discrete components partition, said power unit arranged in the lower stage, while an unconfined space of the upper stage is filled with a hardened material forming a power transfer pad. 2. The transport system according to claim 1, characterized in that the partition between the stages is arranged between adjacent legs along a sinusoid line relative to the conjugated working surface for travelling movable units with a maximum distance from each other in the midspan. 3. The transport system according to any one of claims 1 or 2, characterized in that the housing is a U-shaped profile. 4. The transport system according to any one of claims 1 or 2, characterized in that the housing is an upturned U-shaped profile and provided with a gag in the form of a band or a chute. 5. The transport system according to any one of claims 1 to 4, characterized in that the rail housing is provided with an attachment head with a working surface for travelling movable units. 6. The transport system according to any one of claims 1 to 5, characterized in that the rail housing has a variable height increasing to the midspan between adjacent legs. 7. A string transport system, comprising at least one monorail fixed on legs in the form of a pre-stressed power unit enclosed in a housing with conjugated working surface for travelling movable units, characterized in that the rail housing is made with a telescopic raising forming an upper stage in the housing, whilst the power unit is arranged in the lower stage and the conjugated working surface for travelling movable units is arranged on the housing telescopic raising wherein the upper and lower stages are separated by a solid, perforated or built of discrete components partition. 8. The transport system according to claim 7, characterized in that the partition between the stages is arranged between adjacent legs along a sinusoid line relative to the conjugated working surface for travelling movable units with a maximum distance from each other in the midspan. 9. The transport system according to any one of claims 7 or 8, characterized in that the telescopic raising is a U-shaped profile. 10. The transport system according to any one of claims 7 or 8, characterized in that the telescopic raising is an upturned U-shaped profile. 11. The transport system according to any one of claims 7 to 10, characterized in that the telescopic raising is provided with an attachment head with a working surface for travelling movable units. 12. The transport system according to any one of claims 7 to 11, characterized in that the telescopic raising has a variable height increasing to the midspan between adjacent legs. 13. A method for manufacturing and erecting a span stretch of a string monorail, comprising tension in a span a power unit between adjacent legs, erection thereof in a housing, filing the housing with a liquid hardening material and fixing it between the legs, characterized in that prior to erection a sinusoidal surface of separation it on two stages is formed on the span length along normal to its plane, the surface being a solid or built of discrete components partition and during erection said surface rests upon the pre-stressed power unit. 14. The method according to claim 13, characterized in that the sinusoidal surface of separation is formed by pre-filling the upper the upper stage with a liquid phase material and its subsequent hardening.
