It is very difficult to build telescopic booms for mobile cranes that are both light and strong. Many techniques exist to retract and lengthen crane booms. While retraction of the crane's boom enhances performance, extending the boom limits its capacity. As the distance increases, it gets more difficult to communicate. The crane's ability to lift weight reduces as it gets farther away from the load. In the past, crane booms couldn't reach new heights, but now they can, making them more adaptable than ever. When the crane's boom is in the maximum angular position possible Crane boom and component stress analysis is used in this study. According to SAE J1078 [2], computations are made by hand. Maximizing the weight and strength of the crane boom will enable it to be more efficient. In this study, crane boom parts are compared.
