ROPE DETERIORATION ELONGATION DIAGNOSIS DEVICE FOR ELEVATOR ROPE DETERIORATION ELONGATION DIAGNOSIS METHOD FOR ELEVATOR AND ROPE DETERIORATION ELONGATION DIAGNOSING PROJECTING MEMBER FOR ELEVATOR

摘要

Is provided between the initial stop position of the balance weight 7 when the car 6 is stopped at the uppermost layer at the time of installation and the weight buffer 11 disposed below the balance weight 7, And the projection member 30 mechanically contacts the balance weight 7 and gives a disturbance when the deterioration extension amount generated in the protrusion member 30 exceeds the preset allowable range. Has a sectional shape in which the frequency of the disturbance imparted to the balance weight 7 becomes a desired specific frequency defined so that the vibration transmitted to the car 6 via the balance weight 7 becomes smaller than a predetermined vibration frequency.;
