Abstract
The article dwells upon the results of study influence shape of path of load’s motion which given with using the sigmoidal functions of traversing single obstacle on the arc with suppression of load’s oscillations to the acceleration of the bridge crane's drive. The possibility of a simultaneous significant reduction of the maximum speed, maximum and average values of acceleration, absolute error of the load position and the full work of the drive of one of the controlled axes of the overhead crane by changing the sigmoidal functions parameters that are produced changes in curvature of the arc for a fixed traveling time.
