The electric pulley cableway system in banana plantation was studied. With the selection of the pulley location, pulley speed, swing angle and swing angular velocity of banana bunch as generalized coordinate variables, the mathematical model was derived with Lagrange equations. The dynamic characteristics were analyzed theoretically and experimentally. The results of virtual test showed that the conveying system with multiple moving mass in series was similar to the hoist system with a single moving mass if the distances between each hook point and banana bunch centroid were equal. The test results illustrated that the proposed dynamic analytical model and virtual prototype model were similar to actual system for analyzing the frequency and amplitude of swing angular velocity. The analytical results of virtual prototype model were basically consistent with the actual data. It is evident that the dynamics analytical model is correct and the virtual prototype model gives the realistic reflection to the system dynamics, which provide theoretical reference for the design and modification of the actual system. 
