Designed for longitudinal sliding of bridge structures on metal beams with discrete resting on cross beams (roll-over track).

The longitudinal slide of superstructures is widely used in domestic and foreign bridge construction. This technology makes it possible to reduce the construction time by simultaneously carrying out the installation of the superstructure and the construction of supports.

Pushing force:

  • 398 tf


  • 32 MPa
