The hydraulic door snubbers include a base having one or more connecting plates, one or more mounting plates coupled to the base and configured to receive a link extending from the dipper door, one or more friction plates, and a hydraulic cylinder configured to clamp the mounting plates, the connecting plates, the friction plates and the link together. | 06-19-2014 |
20140165432 | Bucket For Cable Shovel - 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. | 06-19-2014 |
20140202048 | MACHINE HAVING DIPPER ACTUATOR SYSTEM - An actuator system for a machine includes a hydraulic actuator connected to a dipper of the machine, and a hydraulic system fluidly connected to the actuator and configured to selectively direct fluid to the actuator. A component of the hydraulic system is mounted on the dipper. The system also includes an overcenter link coupled to a door of the dipper and biased to maintain the door in a closed position. The actuator is operable to move the overcenter link in a first direction, thereby transitioning the door from the closed position to an open position. | 07-24-2014 |
20150033594 | LATCH SYSTEM FOR A POWER SHOVEL DIPPER DOOR - A power shovel dipper door includes a hollow dipper body defining a first end and a second end opposite the first end, a plurality of dipper teeth coupled to the first end, a dipper door pivotally mounted at the second end, and a latch system for releasably securing the dipper door in a closed position. The latch system includes a latch bar and a latch keeper. At least one of the latch bar and latch keeper is movable between a first position and a second position. The latch keeper is engaged by the latch bar when at least one of the latch bar and latch keeper is in the first position. The latch system further includes removable inserts positioned proximate an interface where the latch bar and latch keeper are capable of engaging each other. One or more of the removable inserts includes a tool steel. | 02-05-2015 |
20150089847 | DIPPER DOOR AND DIPPER DOOR TRIP ASSEMBLY - A mining machine includes a boom, a handle coupled to the boom, a dipper coupled to the handle, and a dipper door pivotally coupled to the dipper. The mining shovel also includes a dipper door trip assembly including a trip motor coupled to the boom, a trip drum coupled to the handle, a linkage assembly coupled to the dipper door, a first actuation element extending directly from the trip motor to the trip drum, and a second actuation element extending directly from the trip drum to the linkage assembly. | 04-02-2015 |
20150345105 | DIPPER FOR A MINING SHOVEL - 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. | 12-03-2015 |
20160024745 | SNUBBER FOR MACHINE - A snubber for a machine includes a housing, a shaft and a pinion that is coupled to the shaft. The housing is mounted on an implement of the machine. The shaft is rotatably received within the housing and operatively coupled to a movable component of the implement. The snubber also includes a cylinder defining a cavity, a piston slidably received within the cylinder, a rack coupled to the piston, and a hydraulic device. The cylinder is at least partly disposed within the housing. The piston divides the cavity of the cylinder into a first chamber and a second chamber. The rack engages with the pinion to convert a rotation of the shaft into a linear movement of the piston. The hydraulic device is in fluid communication with the cavity and controls a flow of fluid between the first chamber and the second chamber to oppose rotation of the shaft. | 01-28-2016 |
20160024746 | SNUBBER FOR MACHINE - A snubber for a machine is provided. The snubber includes a frame that is mounted on an implement of the machine, a shaft that is operatively coupled to a movable component of the implement and a housing that is coupled to the shaft and rotatably received within the frame. The housing defines a cavity that is configured to store a fluid therein in a sealed manner. The snubber also includes at least one brake disc disposed within the housing and configured to rotate with the shaft and at least one brake pad disposed within the housing and configured to frictionally engage with the at least one brake disc to oppose rotational movement of the housing relative to the frame. The fluid is configured to at least partly remove heat generated due to the frictional engagement between the at least one brake disc and the at least one brake pad. | 01-28-2016 |
20160024747 | SNUBBER FOR MACHINE - A snubber for a machine includes a housing mounted on an implement, a shaft, a first member that has multiple helical splines that is coupled to the shaft. The shaft is rotatably received within the housing and operatively coupled to a movable component of the implement. The snubber also includes a cylinder defining a cavity, a piston received in the cylinder and dividing the cavity into a first chamber and a second chamber, a second member that has multiple helical splines and is coupled to the piston and, a hydraulic device. The helical splines of the first and second member engage with each other to convert a rotation of the shaft into a linear movement of the piston. The hydraulic device is in fluid communication with the cavity and controls a flow of fluid between the first chamber and the second chamber to oppose rotation of the shaft. | 01-28-2016 |
