The invention discloses an elevator lower beam structure with car bottom wheels. The elevator lower beam structure comprises a car frame lower beam (1), and two car bottom wheel fixing seats (6) distributed at the two ends of the car frame lower beam (1) are arranged at the bottom of the car frame lower beam (1). The car bottom wheels are arranged on the car bottom wheel fixing seats (6) respectively. One end of an axle of each car bottom wheel (2) is fixed to the corresponding car bottom wheel fixing seat (6), and the other ends of the axles are fixed to the bottoms of car bottom wheel supporting pieces (4). A buffer plate (3) is fixed to the middle of the bottom of the car frame lower beam (1). The car bottom wheel fixing seats (6) are of a hollow structure, and safety tongs (5) are arranged in the car bottom wheel fixing seats (6). Notches corresponding to tong openings of the safety tongs (5) are formed in the upper ends and the lower ends of the car bottom wheel fixing seats (6). The elevator lower beam structure is simple, high in space utilization rate and small in occupied height, and therefore the requirement of an elevator for pit depth can be reduced, and then civil engineering cost is reduced.
