The maximum lifting capacity of the Zoomlion 6515-10 tower crane is 6 tons, and the industry-leading lifting speed is 100m/min; It has a rich range of boom length combinations, with a maximum lift boom length of 60m, a variable boom length of 5m, a minimum boom length of 30m, and seven different boom length combinations. Four major institutions are accelerating the overall efficiency improvement by 35%. Adopting patented lifting safety technology, triple protection against lifting height, dual protection against amplitude collision, intelligent detection of anti hook slip in the electronic control system, leveling control for lifting, and motor control for lifting to prevent lifting accidents. For the first time in the field of tower cranes in China, it has the function of one key load lifting; New techniques for reducing rotation and amplitude. Using fast loading technology, the fastest time from unloading to installation and debugging is 3 hours. The industry's first ETI2.0 secure intelligent control system has improved performance, security, and intelligence.
