  "abstract": "The present application relates to the aerial work platform field, disclosing an electric-driven aerial work platform and a hydraulic system thereof. The hydraulic system includes a superstructure hydraulic system and a substructure hydraulic system. The superstructure system includes a luffing cylinder, a telescopic cylinder, and a superstructure hydraulic pump supplying oil to the two cylinders. The substructure system includes a steering cylinder, a floating cylinder assembly, and a substructure hydraulic pump supplying oil to the steering cylinder and the assembly. The superstructure and substructure systems are independent, with the superstructure pump having a greater rated displacement than the substructure pump. This independent and distributed arrangement overcomes the problem in the prior art, where high-pressure oil from the superstructure hydraulic pump must be transported through the central rotary joint, causing significant pressure loss. The system can save energy, increase efficiency, and achieve emission reduction.",
