Aiming at the problem of sliding protection of Friction Hoist, a kind of Friction Hoist Sliding Protection Device with Hydraulic Loading System as power source is designed. The schematic diagram of Hydraulic Loading System was given, and the analysis model was established by AMEsim. The influence of different parameters such as hydraulic cylinder, accumulator and pipeline on the performance of the system was obtained through analysis. The results show that in order to improve the response time of Hydraulic Loading System, the volume of accumulator can be increased and the length of piping can be shortened. While, the size parameter of hydraulic cylinder should coordinate the displacement response speed of piston rod and the output positive pressure for its optimal design.
