METHOD FOR CONTROLLING THE ORIENTATION MOVEMENT OF THE ROTATING PART OF A TOWER CRANE |
摘要 |
<p>The method involves increasing maximum value of orientation torque produced by an electric motor (16) when a tower crane is in service and while satisfying a condition that wind velocity (V) exceeds a given threshold value. The electric motor is arranged in a gear motor (15) of an orientation electro-mechanism (12) that is connected to a rotating upper part of the crane. The maximum value of the orientation torque is increased based on an angular position of a boom of the rotating part of the crane. An independent claim is also included for a motorized device for controlling orientation movement of a rotating upper part of a tower crane.</p> |
