output results. Additionally, this screen includes icons showing chain characteristic values, the overall appearance of the elevator, and shaft sizing.

When the shaft sizing button is clicked, the visual structure of the shaft along with nu - merical values is

displayed on the screen as shown in Fig - ure 3, which illustrates the drive system shaft sizing vi -

Clicking on the Project button, located next to the bucket type output, chain type output, and chain sprocket output, will display the project drawing details on the screen. 4.1. Material Selection Computer-aided elevator calculations have been per - formed for materials such as clinker, coal, cement, fari - na, ground limestone, slag, fly ash, limestone, sand, salt, and coke. By selecting the name of the material from the dropdown menu, the program obtains the specific grav - ity value of the material from the table and includes this value in the calculations. 4.2. Capacity Selection In the selection of capacity, the capacity table shown in Figure 5, obtained through practical applications, expe - riences, and tests, has been utilized. The capacity values in this table have been incorporated into the program. The capacity values highlighted in yellow represent the most suitable ergonomic capacity values created consid - ering operating conditions and material properties. S
