Each travel carriage (fig.6) includes:
Two travel units each equipped with a
cushion roller mounted on a sealed ball bearing
(1). One of these two travel units is motorised
and has a disengaging mechanism, the other is
equipped with a manual screw brake.
Four guide plates on rollers which guide the rails
during installation (2)
One hydraulically-controlled rail clamp. The rail
clamp is mechanically locked and therefore cannot

The rail clamps must be raised to cope with
obstacles.
