Abstract:

Largescale flattop tower cranes are widely used in largescale construction projects of thermal power, hydropower and nuclear power. It is very important to diminish the swaying of large flattop tower crane slewing mechanism for the safe and accurate lifting. The causes of the swaying of the large flattop tower crane slewing mechanism are analyzed. Two antisway measures taken by the PZQ1400 and the parameter adjustment process onsite are introduced. Finally,a favorable braking effect is achieved, and the swaying of large flattop tower crane slewing mechanism is diminished effectively.
