发明名称 UPPER TURNING BODY FOR CRANE
摘要 PROBLEM TO BE SOLVED: To suppress deformation (horizontal deflection) of a body side bracket. SOLUTION: A reinforcing member 50 is attached to connect a body side right bracket 31 (a right inside bracket 32) and a body side left bracket 36 (a left inside bracket 37). That is, the body side right bracket 31 (the right inside bracket 32) and the body side left bracket 36 (the left inside bracket 37) are formed as an integrated structure. Thus, the bending rigidity of the body side right bracket 31 and the body side left bracket 36 in a horizontal direction (a Y direction in which the body side right bracket 31 and the body side left bracket 36 are opposed) is improved. Therefore, the deformation (the horizontal deflection) of the body side right bracket 31 and the body side left bracket 36 in the horizontal direction (the Y direction) when a load in the horizontal direction (the Y direction) is applied can be suppressed.
