A movable lift device including a rotatable bed which can be lifted or rotated by a user, with laying a user thereon. The movable lift device having a rotatable bed includes a base frame comprising a plurality of wheels installed therein; a post rotatably coupled to the base frame, the post upwardly extended from the base frame a predetermined length in an “L” shape; and a bed comprising a bed part that is able to ascend along the post, the bed part allowing a user to lie thereon. The post rotatably supporting the bed has an “L” shape and the supporting point of the post rotatably supporting the bed is formed in the center of the base frame, such that the structure may be stably maintained even when the bed having the patient lying thereon is rotated, only to prevent an accident of overturning the movable lift device.
