The impact of changeable operating conditions on the deceleration of progressive safety gears of PP 16 type and CHP 2000 new design is presented by the authors. The study was performed in the normal (dry friction) operation conditions (S) and also with the use of mineral oil lubricant (OM). The values of braking delays were recorded with the load of 4 kN and 10 kN applied. Statistical and wavelet analyses were performed to determine variability and waveforms of the system response. The authors reported the differences in dynamical characteristics of the examined safety gears designs in the frequency response. Furthermore, the asymmetry of the acceleration distribution is discussed in this research study.
