The present invention relates to a cart for stairs which includes a loading unit (100) of a lower part to load and store articles wherein the loading unit (100) is minimized by having a folding function where a spread loading unit (100B) is folded in a state of a folded loading unit (100A). A handle unit (200) includes a handle fixing unit (208) fixating the handle unit around a rotating handle body (202) in a desired direction depending on the loaded articles on an upper part. Moreover, an operation button A (205) and an operation button B (206) are installed in the upper part for usage, and the cart for stairs has a height control function to use an operation button C (207) and an operation button D (208) when a user changes a position of the handle for convenience. A brake system using a wheel (401) driving on a flat ground for safety is also included to prevent a fall from the stairs. An initial ascending point (500A) and an initial descending point (500C) on the stairs are distinguished for driving on the stairs; thereby when an ascending mode is set, the cart starts from the initial ascending point (500A), and in a descending mode, the cart starts from the initial descending point (500C). As such, a stair driving wheel (501) is driven in a fan shape when driving on the stairs, thereby not requiring unnecessary space, being safe, and having excellent transmission force for power. |
