    • A system and method for monitoring a first wire rope and a second wire rope is provided. The first and second wire ropes each include a contact portion that contacts a sheave, a first end portion, and a monitored portion that extends between the contact portion and the first end portion. The sheave electrically connects the contact portions of the first and second wire ropes. The system includes a controller that is electrically connected to each of the first and second wire ropes to form a circuit with the monitored portions of the first and second wire ropes. The controller selectively applies a signal to the monitored portions of the first and second wire ropes and determines an electrical characteristic thereof. The controller uses the determined electrical characteristic to determine a condition of the first and second wire ropes.
    • 提供了一种用于监测第一钢丝绳和第二钢丝绳的系统和方法。 第一和第二钢丝绳各自包括接触滑轮的接触部分,第一端部和在接触部分和第一端部之间延伸的被监视部分。 滑轮电连接第一和第二线缆的接触部分。 该系统包括电连接到第一和第二钢丝绳中的每一个的控制器,以形成具有第一和第二钢丝绳的被监测部分的电路。 控制器选择性地将信号施加到第一和第二线缆的被监测部分,并确定其电特性。 控制器使用确定的电特性来确定第一和第二钢丝绳的状况。

    • The invention relates to a method in rope condition monitoring of an elevator, in which method at least the following steps are performed: elevator suspension and/or transmission ropes are reeled and packed on a rope storage unit, and thereafter electrical resistance between a first point and a second point of elevator suspension and/or transmission ropes is measured first time, and thereafter a threshold value is determined based on the measurement, and thereafter rope is delivered into an installation site, and thereafter electrical resistance between the first point and the second point of said suspension and/or transmission ropes is measured second time, and thereafter results of said second time measurement are compared with said threshold value, and if said second time measurement meets said threshold value, predetermined actions are carried out. The invention also relates to an arrangement in rope condition monitoring of an elevator.
    • 本发明涉及一种电梯绳索状态监测方法,其中至少执行以下步骤:将电梯悬挂和/或传动绳索卷绕并包装在绳索存放单元上,然后在第一点 并且首先测量电梯悬挂和/或传输绳索的第二点,然后基于测量确定阈值,然后将绳索输送到安装地点,然后将第一点和第二点之间的电阻 第二次测量所述悬挂和/或传输绳索的点,然后将所述第二时间测量的结果与所述阈值进行比较,并且如果所述第二时间测量满足所述阈值,则执行预定的动作。 本发明还涉及一种电梯的绳索状态监测装置。
