Abstract: A shovel includes a dipper, a hoist rope supporting the dipper, and a bail assembly. The bail assembly includes a bail configured to be coupled to the dipper and an equalizer including a mounting block configured to receive a portion of the hoist rope. The bail is pivotable about a bail axis and defines a first side. The equalizer is pivotably coupled to the bail. The equalizer is pivotable about an equalizer axis that is parallel to the first side of the bail and is offset from the first side.

Abstract: A dipper assembly for a mining shovel includes a dipper body, a dipper door pivotably coupled to the dipper body, an arm, a housing coupled to one of the body and the door, and a piston. The arm includes a first end pivotably coupled to the body and a second end pivotably coupled to the door. The movement of the door relative to the body drives the arm to pivot relative to the body. The housing includes an inlet in fluid communication with a fluid source, an outlet, and a cylinder partially defining a pump chamber in fluid communication with the inlet and the outlet. The piston is movable within the cylinder and biased in a first direction. The pivoting movement of the arm causes the piston to move in a second direction opposite the first direction. The movement of the piston changes a volume of the pump chamber.

Abstract: A dipper assembly includes a body defining an outer surface and an opening, a door pivotably coupled to the body, and a latch mechanism releasably securing the door relative to the body. The door is pivotable between a closed position in which the door is positioned adjacent the opening and an open position in which the door is positioned away from the opening. The latch mechanism includes a latchkeeper and a latch member engaging the latchkeeper. The latch member is coupled to one of the body and the door and the latchkeeper is coupled to the other of the body and the door. The latchkeeper includes an end surface and a stop member coupled to the end surface. The stop member engages the one of the body and the door when the door is in the closed position. The stop member is extendable relative to the end surface.
