The invention relates to an aerial work platform traveling chassis with a pit protection structure. The aerial work platform traveling chassis comprises a chassis, a traveling device, a pit protection mechanism and supporting leg structures. The pit protection mechanism comprises a left pit plate, a right pit plate, two first pit connection plates, two second pit connection plates, two third pit connection plates, a fourth pit connection plate, two moving seats, two guide shafts, two limiting plates and two moving seat pressure springs. Each supporting leg structure comprises a frame plate, a supporting leg seat plate, a supporting leg mounting plate, an outer supporting pipe, an inner supporting pipe and a supporting foot. The aerial work platform traveling chassis with the pit protection structure has the advantages that stability in traveling and steering is improved, and the supporting leg structures are simple in installation and easy to assemble.
