Research on the method of measuring effective energy for quayside container crane based on weighted average method

Abstract

With the rapid development of the world economy, more and more quayside container cranes are put into use in ports. The quayside container crane has the characteristics of large quantity, large power consumption and great energy saving potential. In order to save energy of quayside container crane, the key is to accurately measure the effective energy, the supply energy and the energy utilization efficiency. The weight of the loaded goods carried by the quayside container crane varies greatly in actual work. The test load in the traditional method is specified as 60% of the rated lifting weight, which is different from the actual situation of the crane. Based on the load state level, this paper puts forward the new concept of weighted average effective energy and optimizes the calculation formula. The new test method provides a basis for the accurate test of the effective energy and the energy utilization efficiency in the future.
