In today's world, there are many demands placed on the product. When designing the string-rail transport flyover, uST designers inevitably face such challenges as the materials selection, calculation of dynamic loads, and taking into account customer requirements.
A costruction material like steel is used worldwide. High strength steel has long been widely used in the transport industry. However, high density, which equals large weight, is a disadvantage that needs to be dealt with.
Aluminium, on the other hand, is the obvious alternative to steel: low density, higher corrosion resistance, high electrical conductivity, market availability. But on the other hand, aluminium — is an expensive material with low tensile strength. The next development step were composite materials. Currently, the most popular and affordable ones are fiberglass, carbon fiber and polymers reinforced with various types of fibers.
As of now, uSky Transport has experience in design and installation of all of the above materials. Test track 1 at the uSky Centre — this is proof of the feasibility of steel structures: reinforcement ropes with yield strengths up to 1,640 MPa, as well as solutions for their connection. Test track 4, on the other hand, is a unique combination of aluminium, composite materials and prestressed high-strength steel ropes. This section also demonstrates the main thing — the route length does not matter for uSky.
The search for new materials and experiences — is an ongoing effort by uST, which promotes entering the market with an already proven and certified product.
