【 摘 要 】

In this paper is presented the experimental analysis of the self-erection mechanism of the self-erecting cranes for the erection process from the transport to the building site state to the normal working state. The force in the rod of the erection hydraulic cylinder and the stress and strain on one of the mechanism's bars were determined experimentally. Measuring the stress and strain was carried out by using strain gauges bonded to the measured element and by using data acquisition equipment. The measurements were carried out in real working conditions on a Potain Igo 18 in a working building site.
