METHOD TO RULE WEIGHT SWINGING ON FLEXIBLE SUSPENSION (VERSIONS) Russian patent published in 2010 - IPC B66C13/06 B66C23/88 

FIELD: transport.

SUBSTANCE: invention relates to methods of ruling pout weight swinging during its lifting by jib crane. Proposed method consists in initiating generation of signals for jig and/or cargo truck drive mechanisms. Note here that cargo gripping element is suspended to cargo rope and/or jig crane cargo truck. Transducers are used to control crane load and spatial position of its jig and/or cargo truck. Digital computer is used to generate drive control signals and prevent cargo swinging at final point of cargo transfer. In compliance with first version, after moving gripping element to cargo, computer is used to forecast displacement of the point or assembly load rope suspension to jig or cargo truck caused by jib deformation under cargo weight. Prior to cutting in lifting drive, control signal is generated for at least one jig and/or truck drive. Aforesaid suspension pint or assembly is moved into position not above the cargo, but into that whereat, after jig and/or truck deformation and with haulage winch operating, load ropes come into vertical position at the moment cargo lifts off the ground. In compliance with second version, parametres or coordinates of aforesaid final point are entered into digital computer for them to be allowed for in generation of control signals. Said data is entered by control components. Positioning device is arranged in the zone of cargo transfer final point. Computer serves to take into account of operator's priority and corrects cargo transfer trajectory.

EFFECT: higher efficiency, preventing cargo swinging.
