ABSTRACT:
A cutting-head suction-dredger comprises a floating body, a ladder and a cutting-head carried by the lower end of the ladder. The ladder supports against the floating body through a rail guide which is adapted to tilt with respect to the floating body and which extends in the direction of length of the ladder. This prevents that the engagement of the cutting-head upon the ground is disturbed during heaving movements of the floating body.
