介绍了液压提升机的安全性能要求，对液压提升机进行了危险分析和风险评价，确定了各子系统的危险分值，得到了安全设计中必须高度关注的子系统；进行了各子系统的安全可靠度的预计与分配，并简要分析了子系统的安全设计要点，为液压提升机的安全可靠性分析与设计提供了依据。

In this paper, the safety capability was briefly introduced, the hazard analysis and risk assessment through which the hazard value confirmed and the most important subsystems ascertained was carried through, the safety reliability intending and distributing of subsystems were carried out and the safety designing outline was briefly analyzed. All the above work could provide theoretic foundation for safety reliability designing of hydraulic winder.
