Provided is a circuit breaker trolley for an armoured movable alternating current switch cabinet. The top of a lifting structure is provided with a bracket tray, the bracket tray is provided with a movable type locking structure, the lifting structure is a cross folding rod group, the cross folding rod group includes a plurality of cross folding rods in X cross, a bracket table is provided with ahydraulic arm group, hydraulic arms in the hydraulic arm group and the cross folding rods are in one-to-one correspondence, the upper ends of the hydraulic arms are connected with the cross folding rods, the side edge of the bracket table is provided with a control rod for controlling the hydraulic arm group to lift, and movable structures are universal wheels disposed at four corners of the bottom of the bracket table. The circuit breaker trolley has the advantages that the stability of the bracket tray of the circuit breaker trolley is ensured in the lifting process through real-time data, alifting structure assembly is easy to maintain and transport, and the service life of a device can be effectively prolonged; the control rod has a locking function, the bottom universal wheels have dual functions of braking and straight braking, and the operation risk of the trolley is reduced.
