Abstract: The hoisting mechanism of bridge and gantry crane is taken as the research target in this paper. According to the bond graph theory, a bond graph model with wide applicability was established for researching the energy consumption in the hoisting mechanism. In this paper, the bonding primitives for modeling of various components were summarized, which can make different types of cranes directly simulate after parameter replacement. At the same time, this paper also proposes a method to estimate the damping parameters of each resistive element, and the simulation results show that the method is effective. Finally, the paper puts forward the calculation formula of the influence factor of the energy efficiency of each part of the bridge and gantry crane on the overall energy efficiency, and obtains the specific influence factors of the components of the hoisting mechanism on the overall energy efficiency.
