The utility model provides a loading limiting device and a piggyback transport vehicle provided with the same. The loading limiting device comprises a foundation support, a blocking part, a first limiting part and a second limiting part, wherein the blocking part is rotationally arranged on the foundation support; the blocking part is provided with a blocking position where a vehicle is prevented from moving, and a yielding position where the vehicle yields to move; the first limiting part and the second limiting part are both arranged between the foundation support and the blocking part. When the blocking part is located in the blocking position, relative displacement of the foundation support and the blocking part is limited by the first limiting part; when the blocking part is located at the yielding part, relative displacement of the foundation support and the blocking part is limited by the second limiting part. The technical scheme of the loading limiting device and the piggyback transport vehicle provided with the same solves the problems that a highway vehicle is prone to moving in a loading device and the safety performance is low in the prior art.
