PROBLEM TO BE SOLVED: To smoothly control a winding machine, by accurately detecting the variation amount of the car load at landing and the running start thereafter, in an elevator of a single car. SOLUTION: The system is composed to detect the height position in the shaft 9 of a car 1, by detecting mechanisms 13 and 14, and the car load variation value is calculated by an operation unit 11 from the variation value between the height position at the landing and thate at the starting of the car 1. Since a driving machine 12 can control the winding machine 3 in consideration of the variation value of the car load, the elevation starting can be controlled smoothly, even in a single-car elevator in which a strain gage cannot be set between the car frame and the cage. |
