<p>PURPOSE:To improve operating efficiency by shifting a travelling frame back and forth by means of an overhead conveyor, while by pulling in a door hanger conveyed by another conveyor in order to attach or detach a door. CONSTITUTION:When a door D is removed, the door is manually opened in the first place, and is lifted by a door hanger 18 suspended from the carrier rail 20 of an elevator frame 14 mounted on the inside of a travelling frame 7. And after the mounting part of the door was lifted and detached, this door is manually placed on the center of the door hanger 18, and the elevator frame 14 is lowered. When the door is attached, the door hanger 18 carrying the door that advances on the conveyor line is pulled in the carrier rail 20 of the elevator frame 14 in the same way as in the detachment, and only the door is mounted on a body at a higher position in contrast with the case of the detachment, and thereafter, the elevator frame 14 is lowered.</p> |
