PROBLEM TO BE SOLVED: To provide a construction machine, which can respond to a wide variety of work purposes with high cost merit by using a common loader body and freely changing the specifications between a radial lift form and a vertical lift form only by replacement of arms. SOLUTION: When an attachment 3 is mounted on the top end of a radial lift arm 2 the base end of which is pivotally fixed to a required position of the loader body 1, the top end of the radial lift arm 2 traces a single circular trajectory R as the radial lift form, and when the base end of a vertical lift arm 6 is pivotally fixed to the top end of a main arm 4 and the top end of a link rod 5 the base ends of which are pivotally fixed respectively to required position of the loader body 1, and the attachment 3 is mounted on the top end of the vertical lift arm 6, the top end of the vertical lift arm 6 traces a trajectory V approximate to the vertical line as the vertical lift form.
