Elevator Tension Adjustment Method

Abstract

An object of the present invention is to obtain a method for adjusting the tension of an elevator that can achieve labor saving in the entire adjustment work. 【Solution means】The tension adjustment method includes an adjustment amount determination step. The adjustment amount determination step is a step of determining a first adjustment amount applied to the first wire fixing device 21. The first adjustment amount is determined from a value proportional to a value obtained by dividing the tension adjustment value by the equivalent spring constant. The tension adjustment value is the difference between the pre-adjustment tension value and the target tension value in the suspension body 7. The pre-adjustment tension value is the maximum value in the tension fluctuation of the suspension body 7 due to the movement of the car 8. The target tension value is the allowable upper limit value of the tension of the suspension body 7.
