Abstract

See full text

A controlling method for a hook deviation to regulate the deviation angle of a telescopic crane hook, involves following steps: A. Detecting the deviation angle and deviation direction of a rope, which is linked to the hook, in the horizontal plane relative to the direction of gravitational force; B. Judging whether the deviation angle is more than the predetermined value, if the deviation angle is more than the predetermined value, then turning to step C, and if the deviation angle is less than the predetermined value, then turning to step A; C. Compensatively controlling the deviation angle of the hook according to the deviation angle and direction. And a controlling system for the hook deviation and a controlling device for the hook deviation are provided. The method or system or device enables the detection of the deviation angle and direction of the hook in a quick and precise manner, and the compensatory control of the deviation angle of the hook is performed according to the detected deviation angle and direction, thus it avoids overdependence on human factor and reduces potential safety risks.
