Provided is a method for measuring the amount of wear of a groove (13) formed in a metal drive sheave (6). The measurement method includes: a first step of causing the sensor (21) to face a reference surface facing a direction opposite to a direction in which the bottom surface (30) of the groove (13) faces; and a second step in which, after the first step, the thickness of the metal, which is the distance between the bottom surface (30) and the reference surface, is measured by the sensor (21). The measurement method may further include a third step in which, after the second step, the drive sheave (6) is replaced when the thickness measured by the sensor (21) is less than a reference value.

    提供一种对形成于金属制的驱动绳轮(6)上的槽(13)的磨损量进行测定的方法。该测定方法包括:第一工序,使传感器(21)与基准面对置,该基准面朝向与槽(13)的底面(30)所朝向的方向相反的方向;以及第二工序,在第一工序之后,利用传感器(21)测定底面(30)与基准面之间的距离、即金属的厚度。该测定方法也可以还包括如下的第三工序:在第二工序之后,在由传感器(21)测定出的厚度小于基准值的情况下,更换驱动绳轮(6)。
