Abstract
The present application relates to the field of aerial work machinery and discloses a work platform hydraulic system and an electric aerial work platform. The work platform hydraulic system includes a platform cylinder hydraulic circuit and a platform power unit that is arranged on the work platform to supply oil independently to the hydraulic circuit. In the electric aerial work platform using this hydraulic system, a substructure oil pump supplying oil to the main boom working circuit and the platform power unit are independently and distributively distributed. This distributed arrangement enables the platform cylinder hydraulic circuit to be independently supplied with oil by the platform power unit, separating the work platform hydraulic system from other action hydraulic systems. The combination of small-flow and high-pressure platform actions with large-flow and low-pressure actions ensures no pressure redundancy and waste, improving energy efficiency, avoiding complex hydraulic pipeline connections, and achieving long-distance energy transmission.
