Beschreibung
Zusammenfassung:	The utility model discloses a hydraulic loading device for a hydraulic cylinder test system. The hydraulic loading device comprises a medium pump; the first reversing valve is arranged between the medium pump and the lifting hydraulic cylinder; the second reversing valve is arranged between the medium pump and the lateral thrust hydraulic cylinder; the third reversing valve is arranged between the medium pump and the guide rail pressing hydraulic cylinder; the upper computer is in communication connection with the controlled end of the first reversing valve, the controlled end of the second reversing valve and the controlled end of the third reversing valve; the upper computer controls the first reversing valve, the second reversing valve and the third reversing valve to act. The loading loops of the lifting hydraulic cylinder, the side pushing hydraulic cylinder and the guide rail pressing hydraulic cylinder are integrated, the medium pump is used for being matched with the action of the reversing valve to p
