The invention relates to the field of engineering machinery, and discloses an aerial work platform. The aerial work platform comprises a first hydraulic system which comprises a rotary table executing mechanism arranged on a rotary table, an arm frame executing mechanism arranged on an arm frame, and a first control valve and a first electric pump set which are both arranged on the rotary table; the rotary table executing mechanism and the arm frame executing mechanism are both controlled by a first control valve, and the first electric pump set supplies oil to the first control valve. The second hydraulic system comprises a platform executing mechanism arranged on the working platform, a fly jib executing mechanism arranged on the fly jib, and a second control valve and a second electric pump set which are arranged on the working platform; the platform executing mechanism and the fly boom executing mechanism are both controlled by a second control valve, and a second electric pump set supplies oil to the second control valve. A power supply module and a control module. The problem that an oil supply pipeline of a centralized hydraulic system is long is solved, and the effects of reducing system energy consumption and improving the response capacity of a tail end executing mechanism are achieved.
