ABSTRACT:
The present disclosure is related to a front frame lifter for use in a walking supporter. When encountering obstacles on a path, a user can let down a footboard through a controlling plate and then lift the front frame by means of leverage by stepping on the footboard. Thus, the user can pass through the obstacles easily. Moreover, the lifting device can be applied to other carts such as a shopping cart or a perambulator with the same effect.
