Abstract

Determination of centre of gravity of rotational handling machines with the rail undercarriage can be conducted by the measurement of rails strains induced by the wheels of driving machine. At the properly selected combination of superstructure locations with respect to undercarriage, it is possible to eliminate the systematic measurement failures. Determination of centre of gravity is necessary for proper weighing of the machine and selection counterweight. Otherwise it can cause the loss of stability or fast degradation of superstructure rotation bearing.
