Non-destructive testing of safety equipment without the use of physically-damaging and clumsy test weights - Intelligent Inspection of Elevators

摘要

There are systems available that now allow elevators to be tested more accurately and efficiently without weights. What matters, above all, is correct detection of all influencing factors in order to carry out a proper calculation of the full-load test result. A major factor is the influence of the counterweight at the exact instant the safety gear is triggered. The patented methods and sensors of the Henning ELVI system allow elevator safeties to be evaluated with a non-destructive test process. Adding masses of weight to the car only serves to further stress the people conducting the test and the elevator safety equipment being checked and also causes unnecessary wear and tear to the complete elevator cabin and system.
