ABSTRACT
The analysis of private tests is presented in the article. The applicable tests refer to accelerations, the level of the sound pressure as well as to the sound power emitted by the passenger lift cabin at different technical conditions of the lift. For a group of lifting devices the accelerations were tested at three axes with the use of an accelerometer. The accelerometer was placed in the central part of the cabin with simultaneous measurement of the acoustic parameters with the sound analyzer equipped with the sound volume double microphone probe. The attempt was made to determine the impact of the frame - cabin system construction as well as the lift technical condition on the recorded parameters. It can allow to establish the limit values of the lift structure parameters under which a rapid drop of comfort takes place while travelling in the lift as well as to indicate those construction elements the modification of which would affect the improvement of the operation noiselessness.
