The invention belongs to the field of hydraulic systems, and particularly discloses an electro-hydraulic integrated driving system of an aerial work platform. The electro-hydraulic integrated driving system of the aerial work platform comprises a hydraulic pump, an oil tank, a steering system and a lifting system, wherein the hydraulic pump is driven by a driving motor; the oil tank is arranged on one side of the hydraulic pump; the hydraulic pump, the driving motor and the oil tank are all integrated on the surface of a hydraulic cylinder; a one-way valve A is arranged at the output end of the hydraulic pump; the hydraulic pump provides a power source for the steering system and the lifting system and independently controls the steering system and the lifting system; and the steering system comprises an electromagnetic reversing valve A, a one-way valve B, a hydraulic cylinder large cavity, an electromagnetic reversing valve B and a throttling valve element. According to the electro-hydraulic integrated driving system of the aerial work platform provided by the invention, the hydraulic pump, the driving motor, a valve block and the hydraulic cylinder are integrally designed, so that the driving system can be arranged in a narrow space, the design of a compact complete machine is achieved, and the use requirement of the market is met; and due to the fact that multiple pipelines share a channel, the manufacturing cost can be saved.
