Abstract
A suspension conveying device according to the present invention includes screw shafts of two suspension line pulling-up/feeding mechanisms in a conveying traveling body. The screw shafts have low-speed drive regions, in which feed pitches for driven bodies are small, and high-speed drive regions, in which feed pitches for the driven bodies are large. The screw shafts are installed so that the low-speed drive regions and the high-speed drive regions are disposed mutually oppositely as viewed from the driven bodies when a conveyed object supporter is at one end of an elevation/lowering stroke, and the conveyed object supporter is tilted in a middle of the elevation/lowering stroke when the screw shafts are driven to undergo forward/reverse rotation at a fixed speed by a motor.
