However, in this conventional gas cylinder replacement device, the gas cylinder transferred using a skid or the like is vertically erected on the ground by a worker's manual work or a crane, and is loaded into the gas cylinder replacement device.

In particular, when a relatively large-capacity gas cylinder having a length of 1,800 mm or more is applied to such a conventional gas cylinder replacement device, equipment such as a crane is required to load the gas cylinder into the gas cylinder replacement device, and it is connected to a relatively high position from the ground. As a unit is formed and the device is separated for maintenance of the gas cylinder replacement device or an operator uses a ladder or a forklift, there is a problem in that the maintainability is deteriorated.

Accordingly, as shown in FIG. 1 , it is necessary to develop a gas cylinder replacement device that can be applied to a large-capacity gas cylinder in which the gas cylinder (C) is loaded and supplied on the skid (S) in a state lying on the ground.
