In terms of measuring cable extension, it can assist in measurement. The following is a possible method to use the balancer 6 to assist in measuring the extension of the cable:

[0027] Preparation: Ensure that the balancer 6 has been correctly installed and adjusted to the weight of the load, and prepare the measurement tools such as a tape measure, a micrometer or a laser range finder.
