The invention relates to a transport trolley for transporting goods and/or people, especially for transporting children. Said trolley comprises a trolley frame (1) consisting of shoring elements (10, 10null, 11, 11null, 12, 12null, 13, 13null, 133) and at least two wheeled devices (2a, 2b, 2bnull), provided on said frame (1) and including wheels (20a, 20b, 20bnull) for rolling the transport trolley in a transport direction (T) on a ground, one of said wheeled devices, as a front wheeled device (2a) in relation to the transport direction (T) of the trolley, being arranged on the frame (1) in front of the other rear wheeled device (2b, 2bnull). According to the invention, the wheelbase between the front wheeled device (2a) and the rear wheeled device (2b, 2bnull) can be adjusted by means of an adjusting device (11, 11null) on the trolley frame (1). Thereby, the wheelbase, i.e. the distance between a wheel of the front wheeled device and a wheel of the rear wheeled device, can be modified if necessary. When said transport trolley is pushed by a person, for example at a running pace, a longer wheelbase of the trolley is required for achieving the necessary tilting stability.
