Title:
DEVICE FOR DISPLAYING AND RECORDING SWINGING ANGLE OF LOAD SUSPENDED BY CRANE
Document Type and Number:
Japanese Patent JP3113474
Kind Code:
B2
Abstract:
PURPOSE: To provide a device for displaying and recording the swinging angle of a load suspended by a crane, which can easily evaluate and control the automatic operation of a crane.
CONSTITUTION: The swinging angle signal S1 of a hoisted load from a swinging angle measuring device 20 fitted to a crane is corrected on the basis of the crane posture signal S2 and the deflection correcting signal S3 to compute the accurate swinging angle of the suspended load at real time. The obtained swinging angle data is displayed as a waveform of the swinging angle in a display so as to be easily recognized, and the swinging data is recorded in a recording device with a specific format.
