Abstract

The invention relates to a shock absorbing device for seabed dredgers, which is positioned on the last joint of a dredger arm and which is formed by: a stationary steel tube (1) having flanges (2, 3) at both ends; and a shock absorbing system formed by (i) a stationary steel tube (4) with a plate-reinforced flange (6) at one end, (ii) a steel tube (5) including a blind flange (7) reinforced with lugs (8) traversed by a bolt that is secured to the collection system of the dredger, (iii) guides (10) formed by bars welded to the flange (6) and provided with a travel stop element (11) having an inductive sensor, (iv) a rod (12) having one end welded to the flange (7) and another free end, (v) fitted springs (13), said rod (12) forming the spring guide, and (vi) hydraulic brake lines.
