A device for an elevator system has a blocking arrangement and a measuring arrangement, wherein the blocking arrangement connects a counterweight and/or a car of the elevator system to a rail system of the elevator system, and wherein the measuring arrangement maps a force transferred from the counterweight and/or car into the rail system as a force value.

A tension detector may detect and help correct tension in a lift cable. The cable may include a lift cable within a telescopic structure, such as a telescopic tower. The tension sensor may detect when the cable tension is outside a high tension threshold and a low tension threshold and trigger an alert when outside the thresholds. The alert may be an audible alert or a visual alert. A controller may prevent a user from making the tension worse and encourage an operator to correct the tension problem by preventing a winch from expanding or retracting the telescopic structure. The tension sensor may use springs to calibrate the thresholds for the high tension and low tension and a series of pulleys to manipulate an arm to engage a tension sensor.

Embodiments of the present disclosure are directed to a system for monitoring conditions of elevator hoisting members. The system includes a processing device configured to receive an actual resistance data from the one or more pairs of tensile load bearing conductive members, calculate an adjusted resistance data by subtracting the actual resistance data from a baseline resistance data and dividing by the baseline resistance data, input the adjusted resistance data into a process configured to model the adjusted resistance data into a breaking strength value for the elevator hoisting member, receive the breaking strength value, and determine whether the breaking strength value is below a predetermined threshold value for a rated breaking load of the elevator hoisting member, wherein when the breaking strength value is below the predetermined threshold value, output an alert to the elevator controller to instruct the elevator controller to inhibit movement of the elevator hoisting member.
