A working machine comprising: a machine body which includes a lower traveling body and an upper turning body provided to be turnable on the lower traveling body; a working device which includes a boom axially connected to the upper turning body to be movable up and down and a working member provided to be operable at a front end of the working device to receive a load into the working member; and a controller which is configured to control at least a turning movement of the upper turning body and an up and down movement of the boom in response to an operation of an operator, wherein the controller is configured to control at least any one of a boom raising operation and an upper turning body turning operation so that the working device does not interfere with a load receiving member in a subsequent lifting and turning operation of the operator based on a track of a part of a front end of the working device during at least one lifting and turning operation of transporting the load received in the working member by raising the boom and turning the upper turning body so that the load is input into the load receiving member, and characterised in that the controller is configured to create an estimation map which estimates a load receiving member existence range based on the track of the part of the front end of the working device during at least one lifting and turning operation and to control at least any one of the boom raising operation and the upper turning body turning operation so that the working device does not move within the load receiving member existence range estimated in the estimation map by an operation of the operator in the subsequent lifting and turning operation. a machine body which includes a lower traveling body and an upper turning body provided to be turnable on the lower traveling body; a working device which includes a boom axially connected to the upper turning body to be movable up and down and a working member provided to be operable at a front end of the working device to receive a load into the working member; and a controller which is configured to control at least a turning movement of the upper turning body and an up and down movement of the boom in response to an operation of an operator, wherein the controller is configured to control at least any one of a boom raising operation and an upper turning body turning operation so that the working device does not interfere with a load receiving member in a subsequent lifting and turning operation of the operator based on a track of a part of a front end of the working device during at least one lifting and turning operation of transporting the load received in the working member by raising the boom and turning the upper turning body so that the load is input into the load receiving member, and characterised in that the controller is configured to create an estimation map which estimates a load receiving member existence range based on the track of the part of the front end of the working device during at least one lifting and turning operation and to control at least any one of the boom raising operation and the upper turning body turning operation so that the working device does not move within the load receiving member existence range estimated in the estimation map by an operation of the operator in the subsequent lifting and turning operation.
