To provide a work machine with a lift cab capable of increasing the height and the protruded width of the cab, having a large degree of freedom in selecting the height and the protruded width of the cab, and having an unbulky structure even at transportation.

A revolving superstructure 3 is installed on a travel body 1 via a revolving device 2, and a work front 8 and a lift cab 4 are fitted to the revolving superstructure 3. A first parallel link 5 is fitted to the revolving superstructure 3, a second parallel link 6 is fitted to the first parallel link 5, and the cab 4 is fitted via the links 5, 6. Since two-stage links 5, 6 are used, the height and the protruded width of the cab 4 are increased, and the degree of freedom in selecting the height and the position of the cab is increased. The parallel links 5, 6 are made compact by being folded.
