  • Patent number: 11959258
    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.
