Abstract
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.
