Mounted Cargo Transport Structure for Long-Distance Bulk Hauling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo transport systems face issues with high material consumption, cost, and limited distance capability, as well as rapid wear and reduced length due to significant longitudinal stresses on supporting belts, and increased accommodation area from turn-around switches.
Innovation Solution
A cargo transport complex with a track structure featuring prestressed rail cords, tensioned bogies, and cargo-handling belts with specific tension ratios, grooved profiles, and loading-unloading devices, including turning drums and bypass rollers, to enhance durability, length, and productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If turn-around switches are used in horizontal plane, then cargo transport complex can change direction, but accommodation area increases
Solution Approach 1:
The patent transitions from horizontal plane turn-around switches to vertical plane direction changing using inclined sections. The track structure includes inclined sections that tilt the body at angles γ between 45° and 120°, allowing direction changes in the vertical dimension rather than requiring large horizontal areas.
2Productivity
If supporting belt part is used to carry cargo, then continuous transport is achieved, but longitudinal stresses cause rapid wear and reduced length
Solution Approach 1:
The patent extracts the cargo carrying function from the supporting belt by introducing separate cargo containers that rest on the belt. The supporting belt only provides support and guidance, while containers handle the cargo load, eliminating the harmful interaction between belt and cargo that caused rapid wear.
Solution Approach 2:
The patent introduces cargo containers as intermediary elements between the supporting belt and the cargo. These containers serve as mediators that transfer cargo weight to the belt through controlled contact points, reducing direct stress and wear on the belt while maintaining continuous transport capability.
3Force
If rail conveyor system with steel wheels on steel rails is used, then rolling resistance is reduced, but material consumption and cost increase
Solution Approach 1:
The patent replaces rigid steel rail tracks with a flexible supporting belt that can be tensioned between support points. This thin film approach provides the necessary support and guidance functions with significantly less material than a complete steel rail system, while maintaining low rolling resistance through the smooth belt surface.

AI summary
The apparatus is related to cargo transport systems, that use rail track structure as main transport for continuous hauling of lumpy and loose cargoes over distances of increased length. The claimed cargo transport complex of mounted type is installed on supports above ground (water) surface, and consists of two strands located one below the other or in one horizontal line—cargo strand and return strand. The strands are separated from each other on one side by a loading drum and a turning drum, on the other—by an unloading drum and a turning drum, which form loading-unloading devices, respectively. Both strands are fixed in load-bearing carcasses installed on each of the supports, equipped with drive mechanisms, contain track structure including rail cords, which are prestressed and tensioned with longitudinal tension force FR, N, and may contain prestressed load-bearing elements, and bogies with support wheels resting thereon, positioned along the track structure with a pitch L, m, and a cargo-handling belt placed in the carcasses of the bogies, whereupon the cargo is distributed in the cargo strand, the latter is tensioned with longitudinal tension force FG, N. Noteworthy that the bogies and the cargo-handling belt accommodated therein feature a grooved profile of depth H, m, and width S, m.
