An upper turning body (16) mounted on a lower body (12) for a crane includes a turning frame (20) mounted on the lower body (12) to turn freely and a boom (40) provided to the turning frame (20) to be raised and lowered freely. The turning frame (20) includes a pair of attachment brackets (39, 39) to which a base end section of the boom (40) is attached such that the boom (40) is free to be raised and lowered, and a main frame (21) to which the pair of attachment brackets (39, 39) are provided with an interval in the left-right direction of the upper turning body (16). The dimension of the main frame (21) in the front-rear direction of the upper turning body (16) orthogonal to the left-right direction is smaller than the dimension of the main frame (21) in the left-right direction.
