2. Description of the Related Art In general, as a lifting device for a material or the like installed and used at a construction site, a device that moves up and down along a guide rail attached to a tower is often used. However, in the case of such a shape, when the lift is increased, the tower having the guide rail must naturally be stacked high and added. Therefore, the tower is required to have more strength than necessary. As a matter of course, a high head increases not only the equipment cost but also the installation management cost. For this reason, there has been proposed a system in which a wire rope is provided between an upper position of a building and a ground portion so as to be tensioned, and this wire rope is used as a guide rail and a carrier is moved up and down.
