Quayside container crane is the key equipment for loading and unloading container ships and vehicles at the front of container terminal. With the improvement of people's awareness of resources and environment all over the worid, more and more attention has been paid to the energy consumption of quayside container crane. In order to save energy of quayside container crane, the key is to accurately test energy utilization efficiency. The test method is set up according to Chinese Standard The method of checking and measuring energy utilization efficiency for port electric-crane (JT/T 314-2009), which clearly defines the effective energy, the supply energy and the energy utilization efficiency. The test load in the standard is specified as 60% of the rated lifting weight, which is different from the actual situation of the crane. The weight of the loaded goods carried by the quayside container crane varies greatly in actual work. Therefore, it is unscientific to take only 60% of the rated lifting weight as the test load, and the test results can not accurately reflect the actual situation. In the design of quayside container crane, the load state level is determined according to the use conditions and working requirements. This paper optimizes the test method and calculation formula of energy utilization efficiency based on the load state level, and puts forward the new concepts of weighted average effective energy and weighted average supply energy. The new test method is to take all kinds of typical lifting loads as test loads for many times, and equivalent them to a test period. The results of the new test method can accurately reflect the actual situation of the quayside container crane.
