Based on the improvement of 85T bridge crane, the article analyzes the faults and problems of heavy metallurgical bridge crane during production and mainly makes a research on the 85T crane design flaws and reform scheme. Higher power inverter and higher insulation-class motor were used and reformed according to the site and working condition, which reduced the system fail-ure rate, effectively guaranteed the reliability and security of the metallurgy lifting equipment.
