Summary:The main component which plays the key role in any cargo lifting machine is a hydraulic manipulator (HM). At the moment our factories manufacture a whole variety of HM, the main disadvantage of which is a short life span (3 to 5 years at full capacity). In order to increase the life span of a HM it is compulsory to continuously control peak load indicators during its utilization, therefore defining the optimal maintenance periods for the machinery. For controlling the technical condition of assembles and connections, non-dismantle methods of diagnostic are being used. The most perspective of them is the method of vibration measurement. The mathematical model of calculating peak shock loads, appearing if HM connections at the initial time and their relation to diagnosis parameter (vibration amplitude) is presented in the following article, frequency range of shock load is defined.
