<p>A method of hanging a rammer automatically with a hanger guided by a rope comprises that a drawing windlass is mounted under a support arm holder, a guiding rope is wound around the drawing windlass, and one end of the guiding rope passes through a fixed pulley on the top of the support arm holder, then connects with a handle (22) of the rammer after threading the center of the hanger vertically; the rammer is laid on the ground, and when the main windlass controls the hanger to move downward, the hanger moves downward along the guiding rope until connecting with and locking the handle (22) of the rammer, thereby completing hanging the rammer; when the rammer is lifted to a predetermined height, the hanger releases the handle (22) of the rammer, the rammer free falls to the ground, and the guiding rope also falls to the ground with the rammer.</p> |
