Such a stand-type pull-off frame has a latch and a pawl structure, requiring a great deal of effort by the operator, thereby causing musculoskeletal disorders in the worker. In addition, when the stand-type release ladder does not work well, the cable is being unloaded using materials such as scaffolding.

Since the hydraulic jack is adjusted only at a height of approximately 200 mm, which is the height of the stroke, the height of adjustment is very limited, and the height required in actual field requires height adjustment from 500 to 1,500 mm.

For example, Patent Document 1 below discloses "pull-up of cable drum ".

The unloading means of the cable drum of Patent Document 1 described below is provided with a mounting means which is mounted on the base so that the cable drum is detachably and rotatably engaged and can be lifted and lowered on the base so that the cable can be disengaged by rotation of the cable drum, And means for elevating and lowering the elevating means at an arbitrary height according to the standard of the cable drum, and is coupled to both sides of the cable drum as two sets.

Patent Document 2 below discloses a cable drum fixing table.

The cable drum fixing table of the following patent document 2 includes a rotation shaft to which a cable drum is rotatably mounted, a pair of drums that are shaft-coupled to the cable drum at opposite sides of the cable drum, A rotary pressing knob which is screwed to the rotary shaft and presses the pair of drum fixing parts toward the cable drum, a pair of supporting parts, and the pair of supporting parts and the pair of drum fixing parts are connected to each other And a height variable column portion for adjusting a height of the pair of drum fixing portions with respect to the pair of supporting portions.
