Abstract
In order to increase the productivity and reliability of a hydraulic-powered loader crane, the paper considers a method for conducting experimental studies in the plane of changing the outreach of the boom system of a loader crane with a load. Experimental studies were carried out under the condition of only angular movement of the main boom. To carry out experimental studies, an experimental installation of a hydraulic-driven loader crane was designed and manufactured. The measuring and recording equipment has been selected and adjusted. Within the framework of experimental studies of the dynamics of movement of the boom system of a loader crane with a load, a control system for drive mechanisms has been developed, which makes it possible to realize the optimal modes of movement of the links of the boom system. A method of experimental research has been developed, which made it possible to determine the effect of the simultaneous movement of the boom and stick on the oscillations of the load, and the effect of the oscillations of the load on the dynamic loads arising in the boom system and the drive mechanisms of the loader crane.
