Opis:: The proposal of the diagnostics methodology for the passenger lift winch is presented in this article. The selected device is tested against the emitted volume of sound and vibrations observed in the regular operation (driving operation as per agreed testing sequence). Thermal images are prepared to catch incorrect operation of the winch mechanisms. On the basis of received measurements for the sound volume, accelerations (vibrations), the analysis of vibrations frequency and thermal images, the attempt is made to diagnose the winch condition and to indicate possible reasons of the malfunctions condition.

Opis:: The energy performance and operational characteristics of the passenger lift investigated in this study were based on energy consumption data registered throughout the normal duty cycle. An overview is provided of available methods employed to evaluate the energy uptake of passenger lifts, relying mostly on energy consumption measurements taken on a real object over an idealised reference duty cycle. Measurement data were used to determine the energy efficiency rating of the lift during the trip cycle and in the standby mode and the energy demand levels, which are then to be compared with measurement results obtained under the service conditions.

Opis:: The working surface of lift guide rails during operation is exposed to the destructive action of catchers under emergency braking conditions. In most cases, this surface is lubricated with grease, which makes it impossible to visually assess their local wear. The comfort of cabin movement on guide rails and thus the feelings of cabin occupants depend on the condition of guide rails. Therefore, the verification of lift guide rails wear under real conditions (in situ) is quite cumbersome. In order to assess them on a monthly basis, they would have to be completely cleaned and the excessively worn areas would have to be measured with universal measuring tools and re-lubricated. Such activities would only be a waste of time and lubricant.
