ABSTRACT:
A method of automatically deactivating an electronic load oscillation dampener on a crane is presented. In the method, an inching time interval K is determined. In response to motion commands from the crane operator, carriage motion is initiated under the control of the load oscillation dampener so that load swing will be minimized. At the moment motion commands are removed, it is determined whether the time K has expired since the initiation of carriage motion. If the time K has expired, then the load oscillation dampener is deactivated allowing faster and more intuitive response of the crane to operator commands, including a rapid deceleration to a stop. If the time K has not expired, then the load oscillation dampener is kept active, causing load oscillations to be damped for the remainder of the run.
