The present invention relates to a handle attachment device for a crank lifter, in which a crank arm (1) is formed in opposite directions at both ends of a main shaft (X) provided horizontally in a main body (B) of a crank lifter. The crank arm 1 is provided at its distal end with a body plate 6 rotatably supported by a shaft bolt 7 together with a plurality of bearings b so that the support ring 3 of the handle 2 can rotate A fixing flange 5 is integrally formed on the outer circumferential surface of one side of the attached cover ring 4 so that the fixing flange 5 is fitted to the body plate so as to be detachably coupled with the bolt p The attachment strength of the handle is further increased by the combination of the attachment flange and the body plate, and the durability is improved accordingly, so that the crank movement can be performed more safely without a failure.
