Abstract: The traditional manual elevator is operated completely by hand, so the labor intensity of operators is high and their safety is low. In this paper, an automatic turnover elevator was developed and the turnover mechanisms of key parts were optimized. Firstly, the parameters to be optimized were determined according to the requirement of geometric space. Then, the designed virtual model was introduced into the software Admas for kinematics and dynamics simulation. Based on the analysis, the optimal point was determined.Afterwards, an automatic turnover elevator was manufactured according to the optimal point. It is experimentally demonstrated that the elevator can be overturned well by virtue of the turnover mechanism and the error between the simulation result and the experimental result is smaller.
