Davit arms are usually employed to handle doors of large size autoclaves. These arms require a guiding mechanism to guide the door in a desired path and locate in the desired position. In this work, various options of door handling / steering mechanisms were examined and finally a four bar mechanism is chosen for detailed design. A Geometric model was developed to understand the path traced by the door for various link angles and lengths. Solid modeling of the door was carried out using Solidworks R and simulation of the path of the door for various angles and lengths of the links of the 4 bar mechanism was also done. The prototype model of the autoclave door was fabricated with a 4 bar mechanism mounted on the davit arm of the door. Number of trials were made by changing link lengths and angles to determine the path of the door, using the CAD geometric model. These results are in agreement with the experimental results obtained using fabricated model.
