METHOD FOR AUTOMATICALLY CONVEYING A LOAD ON A LOAD HOOK OF A CRANE OR EXCAVATOR INCLUDING LOAD SWINGING DAMPER AND PATH CONTROLLER

摘要

A method for automatically conveying a freight suspended to a crane or an excavator is provided to reduce the oscillation occurring at the freight by controlling the crane using a hand-lever signal. A method for automatically conveying a freight suspended to a crane or an excavator comprises the step of determining a working area by selecting two points. One of the two points is determined as a target point through a preliminary direction setting by means of a hand lever. A standard speed for a pivot apparatus and a dumping apparatus is previously set based on the hand lever signal. A changed reference signal for a freight speed in the radial direction and a pivot direction is calculated based on information of the hand lever signal including a start point and a target point in the working space.
