The movements of the screeding machine include:
- The vertical parallel displacement of the six hydraulic cylinders for the screeding machine elevation and descent, as well as the autonomous displacement of every cylinder independently, in bringing them to a horizontal position.
- The forward-reverse displacement of the screeding machine bucket by two hydraulic cylinders and the simultaneous clamp or release of the steel carrier through the clamping units.
- The movement of the gravel flow flap.
- The operation of the hydraulic safety clamping units for the forward –backward bucket displacement.
