Claims

[Scope of Claim for Utility Model Registration] 1. The league is installed on the top of the league of a pile driver with the league in a horizontal position, and when installed, it is hung by hanging the hanging member fixed to the top sheave bracket. A top sheave, characterized in that the top sheave includes, as a hanging member fixed to the top sheave bracket, a horizontal member whose hanging position is movable in a plane parallel to a connection plane to the league. 2. The top sheave according to claim 1, wherein the distance of the hanging member from the connection surface is greater than or equal to the distance from the connection surface to the center of gravity of the top sheave. 3. A utility model registration claim characterized in that the hanging member includes a horizontal member whose distance from the connecting surface is smaller than the distance from the connecting surface to the center of gravity of the top sheave, and a horizontal member whose distance is larger than the distance from the connecting surface to the center of gravity of the top sheave. Top sheave as described in paragraph 1.
