Modular Transition Track System (MTTS)

Principles

In large ports, shipyards, or docks, the concrete foundations of quay walls and finger piers or shiplift platforms are poured independently, with expansion joints installed between them to accommodate thermal expansion and contraction. When large vessels berth at finger piers, they exert instantaneous lateral impacts, causing simultaneous horizontal and vertical displacement between the quay wall and the finger pier or between the quay wall and the ship lift platform. Heavy-duty rails laid over these expansion joints are subjected to multi-directional displacement or settlement due to differential movement between the two sides of the joint, which can disrupt smooth rail operation, leading to bending, buckling, or even fracture— severely compromising transport safety.

To address this, SINCHOLD has developed an innovative, globally unique solution— the Modular Transition Track System (MTTS). This system effectively accommodates rail displacement variables in the X, Y, and Z axes, overcoming vertical displacement of 25mm, lateral displacement of 25mm, and longitudinal displacement of 35mm between land-based quay walls and extended finger piers. It perfectly resolves the complex mechanical stress variations at these locations, ensuring that travelling equipment can pass safely and smoothly over the transition module (MTTS) without stopping.

    Applications

    SINCHOLD has secured a patent for the Modular Transition Track System (MTTS) designed for the dock expansion joints, reinforcing its commitment to serving global clients with cutting-edge solutions. The system has already been successfully deployed in the Middle East market, where extreme day-night temperature variations pose significant challenges to rail systems. The practicality and reliability of SINCHOLD's modular transition track system (MTTS) have been thoroughly validated in these demanding conditions.

    In Saudi Arabia, SINCHOLD Modular Transition Rail System has earned strong recognition from Aramco, providing new operational support for the oil giant. Moving forward, SINCHOLD remains dedicated to solving industrial challenges worldwide, delivering superior design concepts to global customers.
