摘要： An upper turning body mounted on a lower body for a crane includes 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. 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, and a main frame to which the pair of attachment brackets are provided with an interval in the left-right direction of the upper turning body. The dimension of the main frame in the front-rear direction of the upper turning body orthogonal to the left-right direction is smaller than the dimension of the main frame in the left-right direction.
