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.
Claims19
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.
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.
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 service platform has at least one set of jaw member contact points, the at least one set of j aw 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.
