Damping element for excavator buckets

A bucket (2) with a door (4) for a cable excavator shovel comprising push cables (6) connected to the bucket (2) to control its inclination to cushion impacts of the bucket (2) on a boom (3) of the excavator shovel, improving protection of the boom (3) and the push cables (6) of said excavator shovel and facilitates maintenance of the excavator shovel, wherein the bucket (2) has a shock-absorbing element (1) mounted, the shock-absorbing element (1) comprising:

• an elongated metal base (9), hollow inside, comprising joining surfaces (10) at each end and configured to join to an upper part of the door (4) of the bucket (2) a central longitudinal recess (12) defining an intermediate space (7);
• and
• two rubber pieces (8) fixed to the metal base (9), said rubber pieces (8) being separated by the intermediate space (7) defined by said central longitudinal recess (12),;
• wherein the shock-absorbing element (1) is mounted on the bucket (2) at the upper part of the door (4) through the joining surfaces (10) of the elongated metal base (9), and
• wherein the intermediate space (7) defined by the central longitudinal recess (12) is configured to receive the push cables (6) of the bucket (2), allowing said push cables (6) to remain between the two rubber pieces (8).
