Abstract

A lifting device to be attached to a wheel assembly, suitable for lifting the wheel assembly onto an obstacle; the lifting device comprises a lifting brace (1) that rotates around a pivot axis (8) that is attached to the fork (5), parallel to the wheel axis (20) and comprises a spring element 10 that forces the lifting brace (1) to stay in the upper position of rotation; the lifting brace (1) comprises a support arm (14) and a guide arm (13) whereby the support arm (14) and the guide arm (13) both are extending in a direction opposite to the pivot axis (8); the support arm (14) and the guide arm (13) having a mutual angle C to each other, in such a way that the support arm (14) and guide arm (13) in the upper position of rotation of the lifting brace (1), in the direction of movement, are projecting out of the front side of the wheel assembly.
