After investigating the issues related to excavators at job sites and during transportation, excavators can be broadly classified into wheeled and tracked types. Wheeled excavators have the advantage of being able to travel on roads, making it easier to move between job sites. However, compared to tracked excavators, they have a higher risk of rollover accidents and there are some work environments where they cannot be operated. On the other hand, tracked excavators are well-suited for various work environments thanks to their track-based wheel structure, but they cannot travel on roads. Therefore, tracked excavators must be transported on trucks between job sites, during which rollover accidents can sometimes occur. According to interviews with excavator operators, most consider tracked excavators to be safer and more efficient in work environments compared to wheeled ones. However, users with limited capital often start by using wheeled excavators due to the lower initial cost, then save money and resell them to purchase tracked excavators and trucks. To address these issues, I propose a new wheel structure design that improves the existing excavator wheel system by combining the functions of both wheels and tracks.
