The invention discloses a hydraulic walking system and a self-walking type aerial work platform. The hydraulic walking system comprises a first hydraulic motor, a second hydraulic motor, an oil supplydevice, a flow distributing and collecting valve, a bypass pipeline and a control valve bank. The first hydraulic motor comprises a first oil port and a second oil port. The second hydraulic motor comprises a third oil port and a fourth oil port. The oil supply device is used for supplying oil to the first hydraulic motor and the second hydraulic motor and comprises a fifth oil port connected with the first hydraulic motor and the second hydraulic motor. The flow distributing and collecting valve comprises a flow collecting oil port, a first flow distributing oil port and a second flow distributing oil port, the flow collecting oil port is connected with the fifth oil port, the first flow distributing oil port is connected with the first oil port, and the second flow distributing oil portis connected with the third oil port. The bypass pipeline comprises a first pipeline with the two ends connected with the first flow distributing oil port and the fifth oil port correspondingly and asecond pipeline with the two ends connected with the second flow distributing oil port and the fifth oil port correspondingly. The control valve bank comprises a first on-off valve used for controlling the first pipeline to be on and off and a second on-off valve used for controlling the second pipeline to be on and off.
