The invention relates a servo oil source of a hydraulic elevator. The servo oil source of the hydraulic elevator comprises a servo oil pump, an oil cylinder used for driving the elevator to ascend and descend and an oil way assembly enabling the servo oil pump and the oil cylinder to communicate, an inlet of the servo oil pump communicates with an oil tank, the oil way assembly comprises a positive pressure oil way which communicates with an outlet of the servo oil pump, the other end of the positive pressure oil way communicates with the oil cylinder, and when the servo oil pump pumps hydraulic oil into the oil cylinder through the positive pressure oil way, the oil cylinder drives the elevator to move upwards. The servo oil source of the hydraulic elevator has the effect of improving the comfort of lifting equipment.
