The paper puts forward a finite element analysis method verifying the mechanical property of drums, and performs analysis and verification for the lifting mechanism before and after improving the structural design.The result shows that the finite element analysis method put forward can guarantee design and operation safety of the lifting mecha-nism, providing an effective finite element analysis thought for similar winch analysis.Based on this, the calculation meth-od for hooking multiplying power shown in the lifting performance table is improved.The method provides guidance for im-proving the correctness of parameters in the performance table.
