Patent number: 10677054Abstract: A cutting bit assembly for a mining machine includes a holder having a first surface, a second surface, and a bore extending therebetween, and a bit having a first end and a second end. The bit further includes a tip, a shank, and a shoulder positioned between the tip and the shank. The shank is positioned in the bore of the holder and defines a shank axis. The shoulder engages the first surface of the holder. The shank includes a projection adjacent the second end. The cutting bit assembly also includes a retainer having a groove and a resilient member. The groove engages a portion of the projection. The resilient portion engages the second surface of the holder and biases the retainer along the shank axis and away from the holder.Type: GrantFiled: July 29, 2016Date of Patent: June 9, 2020Assignee: Joy Global Underground Mining LLCInventors: Randy Arnold, James E.

Patent number: 10624279Abstract: A system and method for controlling a grapple is described in embodiments herein. A variable pressure control may be implemented that controls the pressure applied to a load held by the grapple. An interlock mechanism may be employed on the felling grapple that disables the operation of components of the felling grapple such as a feller. A grapple release mechanism may be activated to release the pressure applied to the load in the event of a malfunction in the felling grapple.Type: GrantFiled: January 31, 2019Date of Patent: April 21, 2020Assignee: Altec Industries, Inc.Inventors: David Mead, Thomas Marietta

Patent number: 10470381Abstract: An insulating felling grapple is used with an insulating utility vehicle. The utility worker stands on the ground near the worksite and remotely controls the insulating felling grapple and the utility vehicle to perform the task. In addition to other standard trimming and removal tasks, the insulating felling grapple is adapted to allow for the removal of energized vegetation material. In one method, the utility worker grasps the energized vegetation material, lifts or moves the energized vegetation material such that it is no longer energized, severs the non-energized vegetation material, and moves the severed vegetation material to a discard location. A boom assembly of the utility vehicle includes a primary insulation segment. The felling grapple includes a secondary insulation segment, as well as a grapple and a feller. The grapple has at least two tines for gripping the energized material. The feller is configured to sever the energized or nonenergized material.Type: GrantFiled: January 31, 2019Date of Patent: November 12, 2019Assignee: Altec Industries, Inc.Inventors: David Mead, Eric Joseph Lumberg
