Abstract

A SWING DISPLACEMENT DETECTOR COMPRISES A SWING DISPLACEMENT DETECTOR (15) FOR DETECTING RELATIVE DISPLACEMENT (X1) BETWEEN A TROLLEY (4) AND A SUSPENDED LOAD (6) IN A CRANE SUSPENDING THE SUSPENDED LOAD BY A ROPE (5) OR THE LIKE; A CRANE UPPER STRUCTURE DISPLACEMENT DETECTOR (16) FOR DETECTING THE DISPLACEMENT OF A CRANE UPPER STRUCTURE (1) SUPPORTING THE TROLLEY FROM THE GROUND SURFACE; AND AN ARITHMETIC MEANS (17) FOR RECEIVING AS INPUTS THE MEASURED VALUE (X1) OF SUSPENDED LOAD DISPLACEMENT BY THE SWING DISPLACEMENT DETECTOR (15), AND THE MEASURED VALUE (X2) OF CRANE UPPER STRUCTURE DISPLACEMENT BY THE CRANE UPPER STRUCTURE DISPLACEMENT DETECTOR (16), AND FOR CORRECTING THE MEASURED VALUE (X1) OF SUSPENDED LOAD DISPLACEMENT BASED ON THE DIFFERENCE BETWEEN THE MEASURED VALUE (X1) OF SUSPENDED LOAD DISPLACEMENT AND THE MEASURED VALUE (X2) OF CRANE UPPER STRUCTURE DISPLACEMENT. THUS, THE VIBRATIONAL COMPONENT OF THE CRANE UPPER STRUCTURE CAN BE ELIMINATED FROM THE MEASURED VALUE OF SWING OF THE SUSPENDED LOAD, WHEREBY THE SWING COMPONENT OF THE SUSPENDED LOAD CAN BE DETECTED HIGHLY ACCURATELY.
