The article describes the procedures for conducting experimental studies of the simultaneous movement of the mechanisms of slewing and trolley movement of the tower crane. The design of the laboratory model of the crane is given, the most significant characteristics to be measured are selected, as well as the corresponding measuring and recording equipment (sensors and device m-DAQ 14). The locations of the sensors on the laboratory model of the crane and the software for the m-DAQ 14 device are indicated. This made it possible to record the kinematic and electrical characteristics during the simultaneous movements of the crane slewing and trolley movement mechanisms. Two optical encoders, a current sensor, an accelerometer and two inclinometers were used in the experiments.
In order to establish the patterns of influence of changing factors (load weight, length of flexible suspension, the initial position of the trolley on the boom and the mechanism that first starts moving), planning of experimental studies and a plan of the first series of experiments is given. It includes sixteen experiments.
In addition, the methods of data collection and processing (interpretation using calibration dependences, noise filtering and determination of derivatives using interpolation methods) are described. The procedures for determining the indicators that will be used in the further analysis of the obtained experimental data are briefly described.
