<p>The present invention relates to a moving-type lifting device comprising a lifting unit including a base having a plurality of moving wheels, a bed unit in which a transferring object is settled, and an ascending and descending frame formed to be upwardly extended from the base, supporting the bed unit to be disposed at a particular height or higher from the floor, and selectively adjusting the height of the bed unit; a buffering unit having one side connected with the ascending and descending frame and the other end connected with the bed unit to reduce vibration generated from the bed unit and including a magnetorheological fluid therein to selectively adjust an attenuation coefficient according to the strength of an applied electric current; and a control unit for sensing the vibration of the bed unit and adjusting the strength of an electric current applied to the buffering unit corresponding to the strength of the sensed vibration.</p> |
