Abstract:
The vibration and sway
of the load in a fixed type tower crane makes it difficult for the load
to take its place accurately, and brings the toppling moment and the
running torque of shock for a whole tower crane. In the paper the
authors set up the cacurate mathematical model of the load
vibration-sway on fixed type tower cranes. A simplified model are
derived in the engineering range. This mathematical model can be used as
means for studying the dynamic characteristic of fixed type tower
cranes, increasing the load vibration-sway, and improving the function
of fixed type tower cranes. Especially the accurate mathematical model
is suitable for a computer simulation.
