The purpose of this study was to analyze the vibration reduction of the construction hoist. The vibration mechanical model and equation of the reduction vibration system were established. Three vibration reduction schemes were proposed and the system's response of the different schemes had been obtained by the vibration equation. The vibration reduction effects of the different schemes were analyzed by comparing with the system's response before and after vibration reduction. Finally, considered the vibration's influence factor, the fuzzy evaluation method of the vibration reduction schemes was built and optimal scheme was acquired by fuzzy integrated evaluation. The findings and the method may provide some reference for vibration reduction analysis of the construct hoist.
