Latching system for dipper

A dipper comprising:

• a body;
• a dipper door pivotally coupled to the body;
• and
• a latching system that latches the dipper door with the body, the latching system including:
• a latch bar that engages with the body of the dipper, the latch bar defining a longitudinal axis centrally passing through the latch bar such that the latch bar is movable along the longitudinal axis, the latch bar including:
• a housing defining a first end and a second end opposite the first end;
• one or more shims removably coupled to the housing proximate the first end of the housing, wherein the one or more shims allow adjustment of the latch bar along the longitudinal axis;
• and
• a wear member defining a wear surface and a wear axis extending parallel to the wear surface, wherein the wear member is removably coupled to the housing proximate the second end of the housing;
• an arm defining a first end portion and a second end portion, the arm being pivotally coupled to the dipper door proximate the first end portion such that the arm is pivotable along a first pivot plane, wherein the arm contacts a portion of the latch bar to move the latch bar along the longitudinal axis;
• and
• a guide assembly coupled to the arm, wherein the guide assembly includes:
• a guide pulley coupled to the dipper door and disposed proximate the second end portion of the arm;
• and
• an actuator wound around the guide pulley, wherein one end of the actuator is coupled to the arm proximate the second end portion of the arm such that a pull applied on the actuator causes the arm to pivot along the first pivot plane,
• wherein an angle of incline defined between the wear axis and the longitudinal axis of the latch bar is in a range of 5 degrees and 45 degrees, inclusive, and is to restrict sliding of the wear member over a latch keeper of the dipper.

A latch bar associated with a dipper, the latch bar defining a longitudinal axis centrally passing through the latch bar such that the latch bar is movable along the longitudinal axis, the latch bar including:

• a housing defining a first end and a second end opposite the first end;
• one or more shims removably coupled to the housing proximate the first end of the housing, wherein the one or more shims allow adjustment of the latch bar along the longitudinal axis;
• and
• a wear member defining a wear surface and a wear axis extending parallel to the wear surface,
• wherein the wear member is removably coupled to the housing proximate the second end of the housing, and
• wherein an angle of incline defined between the wear axis and the longitudinal axis of the latch bar is in a range of 5 degrees and 45 degrees, inclusive, and is to restrict sliding of the wear member over a latch keeper associated with the latch bar.
