6400 tons hydraulic compound crane is the world's largest lifting capacity of land crane, the maximum rated lifting weight of 6400 tons, lifting height of 120 meters, equipment design and manufacturing localization rate of 100%. By the end of 2013, it has been successfully applied to the hoisting of two Fischer-Tropsch synthesis reactors in Shanxi Lu 'an high sulfur coal clean utilization oil-heating integration demonstration project. This paper introduces the composition and basic performance of the crane measurement and control system, which is of great significance to the hoisting of large reactor tanks in petrochemical industry.
