PURPOSE: An easily movable machine for opening residual iron holes of main iron runner and flowing iron pond is provided to stably perform repairing and maintenance of runners and tapping operation by promptly opening the residual iron holes of the main iron runner and the flowing iron pond. CONSTITUTION: The easily movable machine for opening residual iron holes of main iron runner and flowing iron pond comprises a frame(10) at the upper part of one side of which a hook(12) to be caught by the upper part of a hook catching member of the residual iron hole side is installed so that the frame(10) has the same length direction as proceeding direction of a bit(42); a connection part(20) comprising a pair of support plates(22) which are fixed to the central part of the frame(10), penetration holes(24,25) which are penetrated into the support plates(22) respectively in a width direction, and each of which are paired in the plural number in such a way that the penetration holes(24,25) are longitudinally distanced from each other in a certain length, and an indication needle which is mounted on the outer surface of at least one of the support plates(22) by a pin(27) and equipped with a scale(28) that is rotated by its dead load so that the scale(28) is directed to the zero point in case that the frame(10) is in the horizontal state; a digging part(30) comprising a support body(32) which is slidingly mounted on a guide rail(14) that is formed in a length direction of the frame, wherein the bit(42) rotated by being connected to a driving motor(36) is mounted on the support body(32); a driving part(60) comprising a chain(70) which is connected to sprockets(72,73) rotationally mounted on both ends of the frame(10), and a driving motor(62) for driving the chain(70), wherein the chain(70) is connected to the support body(32) of the digging part(30) so that the support body(32) is moved along the guide rail(14); and a control part for supplying a power source to the driving motor(62).
