<P>PROBLEM TO BE SOLVED: To always realize the optimum load compensation by obtaining a certain correction amount without requiring a time and labor. <P>SOLUTION: In the load compensation device for the elevator, a load sensor 6 installed between a car chamber 3a of a car 3 and a support frame 3b; a means 12 for previously obtaining/memorizing a first load signal outputted from the load sensor 6 at load compensation adjustment in the no-loading state; a start shock determination means 11 for operating an angular acceleration from an angular velocity of an angular velocity sensor 9 provided on a winding-up machine 1 and determining start shock from the angular acceleration and a threshold value; a correction value obtaining means 22 for comparing the first load signal with a second load signal of the load sensor in the no-loading state after determination of the start shock and obtaining the correction value corresponding to the signal fluctuation value; and a load compensation operation means 23 for correcting the second load signal using the obtained correction value and operating the load compensation signal from the corrected load signal are provided. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
