Abstract
With the rapid development of automation and intelligent control technology,the automation research and application of grab-bucket gantry crane,which is widely used in port terminals,has become the focus of many port enterprises,universities and scientific research institutes.In this paper,taking the grab portal crane as the research object,the key technologies such as high-precision redundant control and positioning system based on GNSS,high-precision intelligent three-dimensional scanning technology,grab intelligent anti-shake technology,bucket-throwing and cabin-digging operation technology,multi-machine safety anti-collision system,multi-machine cooperative operation technology,automatic comprehensive security system,remote operation platform based on HMI system,intelligent operation and maintenance technology of portal crane,standardization of automatic portal crane and so on are emphatically introduced.The realization of the automation of the grab portal crane completely changes the traditional driver's working mode and reduces the driver's work intensity and improves the essential safety level of the loading and unloading operation of the grab portal crane.关键词
