FIELD: measuring instrumentation.
SUBSTANCE: invention refers to weight registration system for loads suspended on lifting crane cable. Weight registration system for loads suspended on lifting crane cable includes measurement system for stress metering in cable, and computer device for load weight calculation by stress in the cable. Computer device features compensation unit which models and compensates, at least partially, the effect of indirect load weight calculation by stress in cable. Compensation unit includes cable weight compensation which takes lifting cable weight into account in calculation of load weight, particularly cable length change during load lifting or lowering.
EFFECT: improved accuracy of load weight measurement.
