摘要：
An elevator system in which a controller monitors whether or not a speed of an ascending/descending body reaches a preset overspeed. At a time of maintenance work, a stopper is interposed between a buffer and the ascending/descending body to limit a lowered position of the ascending/descending body. A stopper detector detects installation of the stopper onto at least one of the buffer and the ascending/descending body. When the stopper is detected by the stopper detector, the controller lowers a set value of the overspeed.
