Publication number: 20160017573Abstract: An industrial machine that includes a dipper, a crowd actuation device, a hoist actuation device, a swing actuation device, one or more sensors, and a controller. The one or more sensors generate one or more signals related to a load within the dipper. The one or more signals are received by the controller. The controller determines, based on the one or more signals, whether the industrial machine is operating in an over-loaded condition by comparing a suspended load to a suspended load threshold value. If the suspended load is greater or equal to the suspended load threshold value, the controller takes an action to control the industrial machine. The action taken by the controller can include increasing, decreasing, or otherwise modifying a speed parameter or speed limit, increasing, decreasing, or otherwise modifying a force parameter, etc.Type: ApplicationFiled: July 15, 2015Publication date: January 21, 2016Inventors: Joseph J. Colwell, Michael J. Linstroth, Nicholas R. Voelz

Publication number: 20150204048Abstract: An industrial machine that includes a dipper, a hoist drum, a wire rope connected between the hoist drum and the dipper, a hoist motor, a sensor, and a controller. The sensor generates a signal related to a number of wire wraps of the wire rope around the hoist drum, which is received by the controller. The controller determines, based on the signal from the sensor, the number of wire wraps around the hoist drum. If the controller determines that there are an insufficient number of dead wraps around the hoist drum, the controller sets one or more parameters of the hoist motor. The controller sets each of the one or more parameters of the hoist motor to a value that is lower than a normal operational value for the parameter.Type: ApplicationFiled: January 21, 2015Publication date: July 23, 2015Inventors: Joseph J. Colwell, Michael Linstroth, Nicholas R. Voelz

Patent number: 8943715Abstract: 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.Type: GrantFiled: July 9, 2013Date of Patent: February 3, 2015Assignee: Harnischfeger Technologies, Inc.Inventors: Matthew L.
