Abstract: A device for removing a wear member from a ground engaging surface, the device comprising: a body having cavity and a wear member engaging portion to engage the wear member when the wear member extends into the cavity; a gripper movable relative to the body, the gripper having a bracing member adapted to bear against a portion of the ground engaging surface to thereby provide a load path from the ground engaging surface to the wear member engaging portion; and a first actuator connected to the gripper and the body, to apply a force to the gripper, to urge the gripper to move relative to the body, such that, when the bracing member bears against the ground engaging surface, movement of the gripper relative to the body removes the wear member from the ground engaging surface.

Abstract: A wear member monitoring system for a ground engaging tool, the system including: a measuring assembly having: an emitting device configured to emit a measurement signal towards a wear member of the ground engaging tool; a detecting device configured to detect a reflected measurement signal in response to the measurement signal emitted towards the wear member; and a processor configured to: analyse the reflected measurement signal with a two dimensional reference model; and determine a condition of the wear member based on the analysis of the reflected measurement signal with the two dimensional reference model.

Abstract: A heavy duty excavator bucket is constructed with an exoskeletal structure comprising coupled cast components including a lip member, opposed wing members, junction members locatable between floor and side walls and side and rear walls and a cap rail structure extending between opposed wing members about the upper periphery of the bucket to form an integral structure. Steel plate floor, side wall and rear wall members extend between adjacent exoskeletal regions. The bucket may include a cast arch member extending between opposed wing members and a cast reinforcing member extending between opposed junction members adjacent said rear wall.

Abstract: A lock assembly for an excavator wear assembly, the lock assembly a locking pin having at least one dowel extending outwardly therefrom. The lock assembly also includes a retaining member having a seat and a cavity and a biasing member located within the cavity of the retaining member. The biasing member is adapted to exert a biasing force on the dowel to releasably retain the dowel within the seat of the retaining member.
