The main support frame has at least two support frames, a connecting frame for connecting the support frames, and wheels installed to an end of each support frame to move the support frames. The base plate is installed to the connecting frame of the main support frame by a first hinge coupling portion to be able to pivot in one direction and thus be folded toward the main support frame. The auxiliary support frame is supported by a second hinge coupling portion at an end of the base plate, and has an adjustable length. The lifting unit has a housing installed to the base plate, a rope winder, installed to a rotary shaft which is provided to the housing, for lifting a heavy weight, a chain wheel for moving a chain, and a driving part for forwardly or reversely rotating the rotary shaft. |
