Abstract

Provided is an aerial work platform, including a first hydraulic system, a second hydraulic system, a power supply module, and a control module. The first hydraulic system includes a turntable actuator on a turntable, a boom actuator on a boom, and a first control valve and a first electric pump set both on the turntable, where the actuators are controlled by the first control valve that is supplied by the first electric pump set. The second hydraulic system includes a platform actuator on a work platform, a fly jib actuator on a fly jib, and a second control valve and a second electric pump set both on the work platform, where the actuators are controlled by a second control valve that is supplied by the second electric pump set. This design addresses the long oil supply pipeline in centralized hydraulic systems, reducing energy consumption and improving end actuator responsiveness.
