And because both ends of the supporting beam 600 are detachably connected with the undercarriage body 100, the supporting beam 600 can provide supporting force for the two crawlers 700, so that the connection between the two crawlers 700 and the undercarriage body 100 in the process of traveling has stronger stability. In addition, since the support beams 600 are detachably connected to the crawler 700 and the undercarriage body 100, there is an advantage in that it is more convenient to replace and maintain the crawler 700.
