5 . 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 ).

6 . The bucket ( 2 ) according to claim 5 , wherein the joining surfaces ( 10 ) are mounted to the upper part of the door ( 4 ) through a welded connection on supports ( 5 ) of the door ( 4 ).

7 . The bucket ( 2 ) according to claim 5 , wherein the elongated metal base ( 9 ) is formed by the union of welded steel plates.

8 . The bucket ( 2 ) according to claim 5 , wherein the rubber pieces ( 8 ) are shaped in the form of an arch guard or sections or pieces shaped in the form of an arch guard.

9 . The bucket ( 2 ) according to claim 5 , wherein the rubber pieces ( 8 ) are fixed to the elongated metal base ( 9 ) by bolts ( 14 ) that go through lateral perforations ( 11 ) included in said rubber pieces ( 8 ) and is screwed into thread perforations ( 13 ) included in the elongated metal base ( 9 ).

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

an elongated metal base ( 9 ), hollow inside, comprising joining surfaces ( 10 ) at each end configured to join to an upper part of the door ( 4 ) of the bucket ( 2 ) and 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
