    摘要： A set of monitoring and prevention of wear of bushings and pins in connections in buckets of electric shovels is disclosed that has the objective of monitoring the condition of bushings to inform the moment of replacement of the component, in addition, to reduce wear by which is subjected to extend its useful life. The assembly comprises devices for locking pins in the bucket connections of electric excavator shovels, such as handles (bail) or padlocks (padlock), restricting the movement of the pins that interact with the bushings during the operation of the electric shovel bucket, preventing that rotate on their own axis so that rotational friction does not occur between said pin and the bushing, reducing wear. The set also includes wear indicators for the bushings of electric excavator shovels that use handles (bail) or padlocks (padlock), allowing the wear status of the bushings to be monitored and reported, to schedule maintenance, replace components and avoid critical failure of components that may generate unscheduled stoppages.

    摘要： An apparatus may have a casing defining an inner cavity delimited at least by a circumferential surface portion between a pair of lateral surface portions. A shaft passes through the inner cavity of the casing. A wiper arm rotates with the shaft, the wiper arm having a free end in close proximity to the surface portions of the inner cavity of the casing, the free end of the wiper arm having a contour complementarily corresponding to a profile of the circumferential surface portion of the inner cavity. A dam divides the inner cavity in chambers adapted to accommodate a fluid, with movements of the wiper arm changing the volume of the chambers, whereby the apparatus is configured to allow the fluid to flow between the chambers to oppose the force to the given motions. A cover plate(s) is connected to a lateral side of the casing and defining at least one outer chamber around the at least one end of the shaft and exteriorly of the inner cavity.

    摘要： 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.

    摘要： A digging machine (1) such as a face shovel is controlled in an automated dumping sequence in which the bucket (10, 10′) is pivoted to a first angular orientation before opening and, optionally, re-orienting to a second, slightly more forwardly inclined angular orientation. The first orientation may relieve the front part (20) of the bucket from the load while the second orientation is selected to discharge the load at an optimal trajectory. The bucket may move to a third angular orientation before closing the front part (20) against gravity.
