Abstract
A latching system associated with a dipper door of a dipper includes a latch bar that engages with a body of the dipper. The latch bar defines a longitudinal axis. The latch bar includes a housing, one or more shims, and a wear member removably coupled to the housing. The wear member defines a wear surface and a wear axis extending parallel to the wear surface. An angle defined between the wear axis and the longitudinal axis is less than 45 degrees. The latching system also includes an arm member pivotally coupled to the dipper door such that the arm member is pivotable along a first pivot plane. The arm member contacts a portion of the latch bar for moving the latch bar along the longitudinal axis. The latching system includes a guide assembly having a guide pulley and an actuation member that causes pivoting of the arm member.
