Abstract

A SUSPENDED LOAD STEADYING/POSITIONING CONTROL DEVICE COMPRISES INDEPENDENT DRIVE DEVICES (11, 14) FOR MOVING A CRANE (4) ON TWO RAILS (1), THE SAID CRANE (4) SUSPENDING A LOAD BY A ROPE (5) OR THE LIKE AND TRAVELING ON THE SAID RAILS (1) ACROSS THEM; POSITION DETECTORS (12, 15) FOR DETECTING THE TRAVELING POSITION OF THE SAID CRANE(4) ON EACH SAID RAIL (1); SPEED DETECTORS (13,16) FOR DETECTING THE TRAVELING SPEED OF THE SAID CRANE (4) ON EACH SAID RAIL (1); A SUSPENDED LOAD SWING DISPLACEMENT DETECTOR (17); AN ARITHMETIC MEANS (21) FOR CALCULATING, BASED ON INPUTS, OPERATION COMMANDS FOR THE SAID DRIVE DEVICES (11,14) AT TWO LOCATIONS, THE INPUTS BEING THE MEASURED VALUES OF THE TRAVELING POSITIONS AT TWO LOCATIONS BY THE SAID POSITION DETECTORS (12, 15), THE MEASURED VALUES OF THE SPEEDS AT TWO LOCATIONS BY THE SAID SPEED DETECTORS (13, 16), AND THE MEASURED VALUE OF THE DISPLACEMENT OF THE SUSPENDED LOAD BY THE SAID SUSPENDED LOAD SWING DISPLACEMENT DETECTOR (17). THUS, THE SUSPENDED LOAD CAN BE ACCURATELY POSITIONED EVEN IN A CRANE HAVING A STRUCTURAL DEFORMATION.(FIGURE 1)
