The invention discloses an overturning-resisting type crane comprising two longitudinal beam sets and a fixing beam which is arranged between the two longitudinal beam sets and can horizontally move along the two longitudinal beam sets. The fixing beam is provided with a trolley and a main machine. The two ends of the fixing beam are connected with the corresponding longitudinal beam sets throughcarts, and the carts are provided with anti-overturning guide wheel assemblies. Each anti-overturning guide wheel assembly comprises guide wheel shaft fixing seats fixed to two machine frames of the corresponding cart, wherein a guide wheel shaft is arranged between the two guide wheel fixing seats, the guide wheel shaft is provided with a first overturning-resisting guide wheel fixing seat and asecond overturning-resisting guide wheel fixing seat which are capable of rotating relative to the guide wheel shaft, the first overturning-resisting guide wheel fixing seat and the second overturning-resisting guide wheel fixing seat are both provided with overturning-resisting guide wheels, a bolt assembly is connected between the first overturning-resisting guide wheel fixing seat and the second overturning-resisting guide wheel fixing seat, and the bolt assembly is provided with a compensating spring which is used for driving the first overturning-resisting guide wheel fixing seat and thesecond overturning-resisting guide wheel fixing seat to rotate relative to the guide wheel shaft.
