Claims20
A mining machine assembly comprising:
- a dipper arm;
- a dipper coupled to the dipper arm, the dipper having a main body, the main body having a front side, a back side, a bottom side, and a top side, wherein a ground engagement portion extends from the front side, the ground engagement portion including digging teeth;
- and
- a hoist rope attachment assembly coupled to the dipper, wherein the hoist rope attachment assembly includes
- a cam having a rope guide, and
- a cam supporting structure coupled to both the dipper arm and to the cam, wherein the cam supporting structure is configured to rotate with the dipper, such that the cam remains at a constant position relative to the main body of the dipper, regardless of an orientation of the main body.
A hoist rope attachment assembly configured to be coupled to a dipper of a mining machine, the hoist rope attachment assembly comprising:
- a cam having a first plate, a second plate, and a rope guide disposed between the first plate and the second plate, wherein the rope guide includes a curved surface, and wherein the first and second plates in combination with the curved surface define a channel configured to receive a hoist rope;
- and
- a cam supporting structure for coupling the cam to the dipper.
