The invention discloses a rotor type car dumper. The rotor type car dumper comprises a body, a car pressing device, a car abutting device, a hydraulic element assembly, a hydraulic pump station, a hydraulic valve station and a hydraulic pipe, wherein the car pressing device and the car abutting device are arranged on the body; the hydraulic element assembly is arranged in the body and is used for hydraulically driving the car pressing device and the car abutting device; the hydraulic pump station and the hydraulic valve station are separated from a main body and are combined to form a secondary hydraulic system; and the secondary hydraulic system is connected with the hydraulic element assembly through the hydraulic pipe. By using the rotor type car dumper, the failure rate is reduced, the repair process on the hydraulic system of the rotor type car dumper is simplified, the repair time is shortened, the reliability of the hydraulic system is improved, and the operation efficiency of the rotor type car dumper is also improved.
