PURPOSE:To simply and easily rotate and move a cable drum to a horizontal or vertical arrangement and change it, by providing a slide mechanism part to receive the weight of cable drum side surface and thus rotate the cable drum smoothly on the inside of a rotary frame. CONSTITUTION:To make the cable drum 11 held horizontally vertical, by turning a handle 30d of a decelerator 30 for a rotational movement drive 21 in the direction of the arrow A, a gear 29 is slowly driven via a transmission mechanism part 30c through a small gear and a chain 29a. By gradually rotating and moving the rotary frame wherein a rotary shaft 28 is fixed in the direction of the arrow B as the gear 29 moves, the cable drum 11 can be changed vertical. A flange 11a of the cable drum 11 rotated and moved to a vertical position is charged with load via a check plate 11b by a plurality of ball bearings 22a of a smooth mechanism 22 resulting in free rotation. Thus, the cable 10 is led out from the vertically changed cable drum 11 and can be wound up around an insulation cylinder vertically provided. |
