The invention discloses a bogie. The bogie comprises a framework, end axle wheel pairs and a middle axle wheel pair, wherein the end axle wheel pairs and the middle axle wheel pair are separately connected with corresponding axle boxes through bearings of the same kind; each axle box is connected to the framework through an axle-box pull rod and a series of springs; the transverse positioning stiffness of the springs of the end axle wheel pairs is larger than that of the springs of the middle axle wheel pair, and the transverse positioning stiffness of the axle boxes of the end axle wheel pairs is larger than that of the axle box of the middle axle wheel pair. According to the bogie provided by the invention, the transverse positioning stiffness of the end axle wheel pairs is larger, so that the running stability of the bogie on a rail is guaranteed, and snaking motion and instability are avoided; because the transverse positioning stiffness of the middle axle wheel pair is smaller, the curve passing performance of the bogie is guaranteed. When the bogie passes through a curve, the transverse force of the middle axle wheel pair to a wheel rail is reduced, and the wear of the wheel rail, caused by reduced transverse force of the middle axle wheel pair to the wheel rail, can be reduced; besides, the manufacturing cost is reduced, and the maintaining cost of the axle boxes is reduced. The invention further discloses transport equipment which comprises the bogie. The transport equipment generates little wear to the wheel rail and is low in manufacturing cost.
