FIELD: transport.SUBSTANCE: angle feedback data is assumed to be the rope deflection angle signal (?). Said angle feedback data is derived from measurement performed by the transducer arranged at the trolley or nearby it. Said angle feedback data is corrected by compensation for the error caused by speed change. Besides, it is processed for output of crane displacement instructions or other control data related to this crane on the basis of corrected angle data in the real time scale.EFFECT: efficient and reliable measurement of rope deflection angle.34 cl, 27 dwg, 3 tbl |
