Abstract
A handling system for handling ground-engaging wear parts used on earth working equipment includes handling tools to remove and handle wear parts from equipment and/or to install new wear parts. The tools can include a torque or other tool to engage and/or disengage a lock retained by the wear member. The handling system allows an operator maintain a distance from heavy parts being removed or installed, reducing the risk of injury.
