Patent number: 10829912Abstract: A wear assembly for excavating equipment which includes a wear member and a base each with upper and lower stabilizing surfaces that are offset and at overlapping depths to reduce the overall depth of the assembly while maintaining high strength and a stable coupling. The nose and socket each includes a generally triangular-shaped front stabilizing end to provide a highly stable front connection between the nose and wear member for both vertical and side loading. The lock is movable between hold and release positions to accommodate replacing of the wear member when needed, and secured to the wear member for shipping and storage purposes.Type: GrantFiled: November 10, 2017Date of Patent: November 10, 2020Assignee: ESCO GROUP LLCInventors: Christopher M. Carpenter, Donald M. Conklin, James E. Bearden, Severn D. Durand, Dziugas Radzius, Ray J. Morris

Publication number: 20180327238Abstract: An loader is provided that has a body which is pivotable in a mid-section, a primary linkage pivotally mounted to the body, a secondary linkage pivotally mounted to the primary linkage, and a grapple pivotally mounted to the secondary linkage to carry a load positioned forward of the body. The improvement includes means for determining the positions of the primary and secondary linkages, and means for measuring the weight of a load being carried by the grapple. The control system has the capability of receiving from the means the positions of the primary and secondary linkages and the weight of the load and calculating whether the load is in an unstable position. If the load is unstable, the operator is prevented from moving the load to a more unstable position, but is not prevented from moving the load to a more stable position.Type: ApplicationFiled: January 19, 2018Publication date: November 15, 2018Inventors: Dominic H. Tremblay, Severn D. Durand, Brandon K. Gray, John Evans
