First claim

Opening claim text (preview).

The invention claimed is: 1. An upper turning body mounted on a lower body for a crane, the upper turning body for a crane comprising: a turning frame mounted on the lower body to turn freely; and a boom provided to the turning frame to be raised and lowered freely, wherein the turning frame includes a pair of attachment brackets to which a base end section of the boom is attached such that the boom is free to be raised and lowered about a rotational axis extending in an axial direction parallel to a left-right direction of the upper turning body, and a frame body to which the pair of attachment brackets are provided with an interval in the axial direction, and the frame body is formed of a plurality of divided frames arranged side by side in the axial direction, adjacent divided frames of the plurality of divided frames being separably joined to each other, wherein the plurality of divided frames include a middle divided frame attached on the lower body to turn freely, a one side divided frame arranged on one side of the middle divided frame and separably joined to one end section of the middle divided frame in the axial direction, and an another side divided frame arranged on another side of the middle divided frame and separably joined to another end section of the middle divided frame in the axial direction, and wherein the one side divided frame and the another side divided frame are so disposed as to sandwich the middle divided frame in the axial direction. 2. The upper turning body for a crane according to claim 1 , wherein a left side surface of the left-side divided frame is inclined to approach a right side-most surface of the left-side divided frame toward a rear side, and a right side surface of the right-side divided frame is inclined to approach a left side-most surface of the right-side frame toward a rear side.
