A bucket for use with a cable shovel includes a shell and a door collectively defining a cavity for gathering material to be excavated. The door is pivotally secured about a pivot axis on the shell so that the door can pivot between a closed position for gathering the material and an open position for dumping the material. The pivot axis is positioned forward of an exterior surface of a back wall of the shell to create a shallower and less forceful door swing during dumping. The door has a front portion that is bent towards a digging edge on the shell so that the door has greater strength, improves bucket loading, and moves a portion of the shell away from the highest wear area.
A cable shovel bucket comprising a front wall, an opposite back wall, sidewalls extending between the front wall and the back wall and a door collectively defining a cavity for gathering material during operation of the cable shovel, the door being pivotally secured for gravity activated movement between an open position and a closed position about a pivot axis that extends through the side walls between the back wall of the cavity and the front wall.
A cable shovel bucket comprising a shell including a front end having a digging edge and a rear end having supports to secure the bucket to the cable shovel, and a door pivotally secured to the shell for movement between an open position and a closed position, wherein the shell and the door when closed collectively define a cavity for gathering material during operation of the cable shovel, the gravity actuated door has a front portion proximate the front end of the shell and a rear portion proximate the rear end of the shell, and the front portion of the door is curved toward the digging edge to abut a complementary shaped shell when the door is closed.
