A bucket for a rope shovel formed as a resistant structure against great mechanical efforts which said bucket is subjected to during its operation, said bucket comprising a body (11) formed with a tubular shape leaving in its interior a closed curvature (8), wherein said body is formed by at least one plate (4) which is folded until its ends are butted, requiring weld beads (9a, 9b, 9c) and/or weld plugs (9c) in order to form said body (11) with a tubular shape, wherein said body (11) has in its exterior a plurality of reinforcement layers (12, 13, 14, 15) which are constituted by at least a plate (4) wherein on the lower front portion of the body (11) is present a lip (25) which is formed by a plurality of sheets (25a, 25b, 25c, 25d) overlapped and nested, each sheet being formed by at least one plate (4) wherein in the upper portion of the body (11) engagement means (20, 21, 22) are placed which are also made of at least one plate (4).

A dipper for a mining shovel includes a back wall, a first side wall extending from the back wall, a second side wall extending from the back wall, a front wall disposed opposite the back wall and extending between the first and second side walls, and a dipper door pivotally coupled to a bottom end of the dipper. The dipper door is movable between a latched and an unlatched position relative to the dipper. The dipper door is angled relative to the front wall at an acute angle when the dipper door is in the latched position.

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 tooling system includes a dipper having a lip with a plurality of apertures, the apertures extending at least partially through the lip. The tooling system also includes a modular adapter configured to be inserted partially into one of the apertures along an axis of insertion. The adapter is configured to be releasably coupled to the lip. The adapter includes a first portion configured to extend into the aperture, and a second portion configured to extend out of the aperture. The tooling system also includes a locking system including a fastener configured to extend at least partially into the aperture and couple to the adapter to the lip.

A dragline bucket includes a base member defining a first end, a second end, and a third end. The dragline bucket also includes a first side wall, a second side wall, and an end wall extending from the base member proximate to the third end of the base member such that the end wall is connected to each of the first side wall and the second side wall. The end wall includes a first portion connected to the base member such that a first angle is defined between the base member and the first portion. The end wall also includes a second portion extending from the first portion. The second portion is substantially perpendicular to the base member. The end wall further includes a third portion extending from the second portion such that a second angle is defined between the second portion and the first portion.

The present invention concerns a dipper assembly and parts thereof for use with a mining shovel. The dipper assembly includes: a dipper body having a back wall and an open dipper bottom; a dipper door pivotally coupled to the back wall of the dipper body and moveable between open and closed positions relative to the open dipper bottom; and a latch assembly for releasably securing the door in the closed position. The latch assembly includes a latch keeper and a latch member for engaging the latch keeper. The latch keeper is associated with the dipper body proximate the open dipper bottom and the latch member is coupled to the dipper door. The latch member includes at least one roller to assist the latch member in engaging and disengaging with the latch keeper and to reduce wear on the latch member.
