Improved Method to remove and replace a Wedge Wedge of MDE and improved Gravity Gravity

摘要

The present Invention relates to improved method to remove and replace a Wedge of gravityWith respect to an operating position of a connection between two parts of Railway Car Free, placed inside a Crossbar structure of the body of the car,Said method is characterized by better understanding the stages Dee: provide a Half Coupler at the Upper end of the wedge; inserting a medium Lift through an Opening provided in eThe ceiling of the bar Body of the car to ensure that Environment Coupler; The Coupler half Lift Connecting the coupling with the elevator and the elevator.,So I get to be with him, pull up on the elevator to extract from the wedge between the two Parties to a location up; Keep The WedgeIn the location Upward; The Lower Wedge from the location up to the operating position; and release the elevator from the Coupler.
