摘　　要：轻小型起重机广泛用于中小型厂房内的物料搬运,在进行长件类物品的吊运工作过程中,由于吊运方式的选择与设计不当常会引发脱钩、脱轨等相关事故,甚至造成人员伤亡。本文以轻小型起重机吊运长件类物品的常见事故为分析对象,对其事故发生原因、过程及相关影响因素进行理论分析,建立长件类物品的吊运模型,分析钢丝绳受力状况及吊点位置,从而得到长件类物品吊运方式的使用原则,以及防止相关事故发生的安全对策,对吊运长件类物品的安全监督工作具有一定的指导意义。The light and small-size crane is widely used for material handling in medium and small-scale plant. During hoisting work for elongated objects, certain accidents such as unhooking, derail and the like, or even casualties, will oc- cur due to improper selection and design of hoisting methods. The paper analyzes the accident cause, process and influen- cing factors with the normal accidents of hoisting elongated materials by light and small-size crane as analysis objects. The hoisting model for long objects is built to analyze the force-carrying conditions of wire ropes and hoisting points, hence to obtain the usage principle for such condition, and safety countermeasures for preventing related accidents, which provides certain guidance for safety supervision of hoisting elongated materials.
