With ever-demanding operation efficiency of container terminals,the operation speed and load capacity of quayside container cranes have been improved.The increasing hoisting load and the running speed of trolley have brought great impact and wear to the trolley track,which further affects the service life of trolley track.In order to further study the service life of the trolley track of large quayside container cranes,in this paper,according to the actual track failure modes,the influencing factors of trolley track service life were summarized.In addition,the trolley track type selection calculation was analyzed theoretically,and the factors affecting trolley track service life and the calculation method of trolley track load spectrum coefficient were deduced.Based on the theoretical influencing factors,the optimized manufacturing and installation processes are put forward hoping to improve the service life of trolley track of quayside container crane.
