A tensioning apparatus for a cable drum is provided to easily maintain a tension unit by mounting a cable tensioning unit for preventing deflection of a cable on a rotation locking shaft. A tensioning apparatus includes a cable drum support frame(3) rotatably installed to an upright stand of a base(1), and a rotation locking shaft(2) detachably mounting a tension unit(10) by a drum locking part(31) of the cable drum support frame. A cable tensioning unit(100) is mounted on one end of the rotation locking shaft to control rotation of a cable drum and thus prevent deflection of a cable. A cable drum transfer unit(200) automatically moves the cable drum support frame up and down to replace the cable drum to be engaged with the rotation locking shaft. |
