Material handling implement with wear component securement

1 . A fastening system for securing a wear component to a lip of a material handling implement, the fastening system comprising:

a clamp configured to engage profiles formed in respective legs of the wear component;

a wedge having opposing first and second faces, the first face being configured to engage the clamp, and the second face being configured to engage a surface of an opening formed through the lip;

a shaft;

an externally threaded member rotatable by the shaft, in which the threaded member is axially displaceable relative to the shaft; and

a biasing device that exerts an axially biasing force against the threaded member.

2 . The fastening system of claim 1 , in which the threaded member is displaceable relative to the clamp along the shaft.

3 . The fastening system of claim 1 , in which the wedge first face comprises teeth engaged with the threaded member.

4 . The fastening system of claim 1 , in which each of the wedge first and second faces are linearly extending.

5 . The fastening system of claim 1 , in which rotation of the shaft simultaneously compresses the biasing device and biases the wedge into the lip opening.

6 . The fastening system of claim 1 , in which compression of the biasing device causes the wedge to be biased into the lip opening.

7 . A method of securing a wear component to a lip of a material handling implement, the method comprising:

positioning the wear component on the lip;

installing a clamp into an opening formed through the lip;

engaging surfaces of the clamp with profiles formed in respective legs of the wear component;

installing a wedge into the opening, a first face of the wedge engaging the clamp and an opposing second face of the wedge engaging a surface of the opening; and

rotating a shaft in the clamp, thereby compressing a biasing device in the clamp and exerting a biasing force that biases the wedge into the opening, in which the rotating comprises rotating an externally threaded member that engages teeth formed on the wedge first face.

8 . The method of claim 7 , in which the compressing comprises displacing the threaded member axially along the shaft.

9 . The method of claim 7 , in which the compressing comprises displacing the threaded member relative to the clamp.

10 . The method of claim 7 , in which the exerting comprises biasing the clamp in a rearward direction relative to the lip.

11 . The method of claim 7 , in which the exerting and the compressing are performed simultaneously.

12 . The method of claim 7 , in which the exerting comprises biasing the wedge second face against the surface of the opening.

13 . A fastening system for securing a wear component to a lip of a material handling implement, the fastening system comprising:

a clamp having opposing inwardly facing surfaces configured to engage profiles formed in respective legs of the wear component;

a wedge having opposing first and second faces, the first face having a series of teeth formed therein, and the second face being configured to engage a surface of an opening formed through the lip;

a shaft positioned in the clamp;

an externally threaded member rotatable by the shaft, and the threaded member being engaged with the wedge teeth; and

a biasing device that exerts an axially biasing force against the threaded member.

14 . The fastening system of claim 13 , in which the threaded member is axially displaceable relative to the shaft.

15 . The fastening system of claim 13 , in which the threaded member is displaceable relative to the clamp along the shaft.

16 . The fastening system of claim 13 , in which the wedge first face is configured to slidingly engage the clamp.

17 . The fastening system of claim 13 , in which rotation of the shaft simultaneously compresses the biasing device and biases the wedge into the lip opening.

18 . The fastening system of claim 13 , in which compression of the biasing device causes the wedge to be biased into the lip opening.
