The invention discloses an airplane landing gear loading device. The device comprises a horizontally arranged loading crowbar, wherein one end of the loading crowbar is vertically connected with a landing gear dummy wheel, a force measuring sensor is connected between the loading crowbar and the landing gear dummy wheel, and the other end of the loading crowbar is connected with a hydraulic actuating cylinder through a multi-degree-of-freedom joint; the lower part of the middle of the loading crowbar is hinged to a movable bearing base, and the movable bearing base is placed on a bearing column; the force measuring sensor and the hydraulic actuating cylinder are both electrically connected to a control system. According to a loading process, when a landing gear is loaded in a test, the control system controls load application of the landing gear through the force measuring sensor, the landing gear is deformed in a loading process, the loading crowbar is inclined, the hydraulic actuating cylinder is retracted,
