The chassis adopts a modular design. Components such as the tracks, drive system, and suspension system can be independently replaced or upgraded, facilitating maintenance and repair. The modular design also enables rapid assembly and adjustment according to different equipment requirements, enhancing production efficiency and flexibility, and meeting the customized demands of different customers for chassis size, load capacity, etc. By using lightweight alloys and composite materials, the overall weight of the chassis is effectively controlled, reducing the equipment's own weight, improving fuel efficiency or power usage efficiency. The lightweight design also facilitates the transportation and installation of the equipment, reducing logistics costs, while not affecting the chassis's load-bearing capacity and structural strength, ensuring stability during high-load operations.
