AI Technical Summary
Technical Problem
In work machines equipped with lifting magnets, vibrations in the boom attachment occur due to the weight of the lifting magnet and the lifting load, leading to inaccurate measurement of the lifting load's weight based on boom cylinder pressure.
Method used
A work machine design that includes a controller with a weight calculating part to measure the lifting load's weight from boom cylinder pressure and a vibration control part to reduce attachment vibrations, thereby improving weight measurement accuracy.
Benefits of technology
The solution enables accurate calculation of the lifting load's weight and reduces vibrations in the boom attachment, ensuring precise weight measurement even under conditions where vibrations might otherwise distort readings.
