In terms of volume, the electric stair climbing vehicle adopts wheeled design, which can move freely in limited spaces such as stairwells or corridors, and can adapt to different types of stairs, including straight stairs, curved stairs and spiral stairs. Compared with the electric stair climbing vehicle, the crawler stair climbing vehicle is bulky, inconvenient to carry and store, and needs more storage space.
