Abstract

A jaw crusher assembly comprising a jaw crushing apparatus and a service platform. The jaw crushing apparatus having first and second opposing jaws, each opposing jaw having a crushing face. The crushing faces opposing each other in an oblique relationship when the opposing jaws are in an at least partially opened state. The service platform provides at least two service configurations within the opposing jaws and being operable between a first service configuration and a second service configuration by rotation of the service platform.

First claim

What is claimed is:

1. A jaw crusher assembly comprising a jaw crushing apparatus and a service platform, the jaw crushing apparatus comprising:
first and second opposing jaws, each opposing jaw having a crushing face, the crushing faces opposing each other in an oblique relationship when the opposing jaws are in an at least partially opened state;
wherein the service platform is configured to provide at least two service configurations within the opposing jaws and being operable between a first service configuration and a second service configuration by rotation of the service platform;
and wherein said service platform has a wedge shaped geometry whereby in said first service configuration said service platform is wedged between said first and second opposing jaws at a first vertical location, and in said second service configuration said service platform is wedged between said first and second opposing jaws at a second vertical location different from said first vertical location.

2. The jaw crusher assembly of claim 1 , wherein the rotation is about a horizontal axis.

3. The jaw crusher assembly of claim 1 , wherein the service platform comprises:
a first platform, the first platform being configured such that when the service platform is in the first service configuration, the first platform is horizontal; and
a second platform that is non-parallel with said first platform, the second platform being configured such that when the service platform is in the second service configuration, the second platform is horizontal.

4. The jaw crusher assembly of claim 1 , wherein the service platform further comprises:
a first spanning portion configured to extend between opposing jaws of the material crushing apparatus in the first service configuration; and
a second spanning portion configured to extend between opposing jaws of the material crushing apparatus in the second service configuration;
wherein the service platform is operable between the first service configuration and the second service configuration by rotating the service platform such that the relevant spanning portion is configured to extend between opposing jaws of the jaw crushing apparatus.

5. The jaw crusher assembly of claim 4 , wherein the first and/or second spanning portions are of fixed length.

6. The jaw crusher assembly of claim 4 , wherein the first and second spanning portions are adjoined at respective first ends and extend therefrom towards respective second ends, the service platform further comprising a third spanning portion extending between the second ends of the first and second spanning portions.

7. The jaw crusher assembly of claim 6 , wherein the third spanning portion is configured to extend between the opposing jaws in both the first service configuration and the second service configuration.

8. The jaw crusher assembly of claim 6 , wherein the first, second and third spanning portions form a triangular arrangement.

9. The jaw crusher assembly of claim 6 , wherein in the first service configuration the third spanning portion and the first spanning portion extend between the opposing jaws, the second spanning portion extending along a crushing face of one of the opposing jaws, or extending along the crushing surface of a liner installed on one of the opposing jaws.

10. The jaw crusher assembly of claim 6 , wherein in the second service configuration the third spanning portion and the second spanning portion extend between the opposing jaws, the first spanning portion extending along a crushing face of one of the opposing jaws, or extending along the crushing surface of a liner installed on one of the opposing jaws.

11. The jaw crusher assembly of claim 6 , wherein the service platform has at least one set of jaw member contact points, the at least one set of jaw member contact points comprising at least first, second, and third jaw member contact points, the first jaw member contact point is a common jaw member contact point locatable at the joined first ends of the first and second spanning portions, the second and third jaw member contact points are locatable at the respective second ends of the first and second spanning portions, at their respective joints with the third spanning portion.

12. The jaw crusher assembly of claim 11 , wherein the jaw member contact points comprise roller means.

13. The jaw crusher assembly of claim 4 , wherein the opposing jaws form a V-shaped crushing cavity when in the at least partially open position.

14. The jaw crusher assembly of claim 13 , further including a third spanning portion extending between said first and second spanning portions, wherein the first, second and third spanning portions form a first wedge shape relative to the opposing jaws in the first service configuration, the first wedge shape forming a wedge between the opposing jaws such that the service platform is held in the first service configuration within the V-shaped crushing cavity of the crushing apparatus.

15. The jaw crusher assembly of claim 14 , wherein the first, second and third spanning portions form a second wedge shape relative to the opposing jaws in the second service configuration, the second wedge shape forming a wedge between the opposing jaws such that the service platform is held in the second service configuration within the V-shaped crushing cavity of the crushing apparatus.

16. The jaw crusher assembly of claim 1 wherein, in the first service configuration, one or both of the opposing jaws have liners or wear plates installed thereon.

17. The jaw crusher assembly of claim 1 wherein, in the second service configuration, one or both of the opposing jaws have liners or wear plates installed thereon.

18. A jaw crusher assembly comprising a jaw crushing apparatus and a service platform, the jaw crushing apparatus comprising:
first and second opposing jaws, each opposing jaw having a crushing face, the crushing faces opposing each other in an oblique relationship when the opposing jaws are in an at least partially opened state;
wherein the service platform is configured to provide at least two service configurations within the opposing jaws and being operable between a first service configuration and a second service configuration by rotation of the service platform,
wherein the service platform comprises:
a first spanning portion configured to extend between opposing jaws of the material crushing apparatus in the first service configuration; and
a second spanning portion configured to extend between opposing jaws of the material crushing apparatus in the second service configuration; and
a third spanning portion extending between the second ends of the first and second spanning portions,
wherein the service platform is operable between the first service configuration and the second service configuration by rotating the service platform such that a relevant spanning portion is configured to extend between opposing jaws of the jaw crushing apparatus,
and wherein the first, second and third spanning portions form a triangular arrangement.

19. A jaw crusher assembly comprising a jaw crushing apparatus and a service platform, the jaw crushing apparatus comprising:
first and second opposing jaws, each opposing jaw having a crushing face, the crushing faces opposing each other in an oblique relationship when the opposing jaws are in an at least partially opened state;
wherein the service platform is configured to provide at least two service configurations within the opposing jaws and being operable between a first service c
