The invention discloses a machine-room-less elevator bearing beam which comprises a main beam, a strip-shaped traction main machine, a traction wheel, a car roof rope returning wheel, a main guide rail, a rope hitch plate, a counterweight rope hitch, a counterweight wheel and a counterweight frame. A plurality of reinforcing ribs are arranged on the front face and the back face of the main beam correspondingly, and a main machine bottom plate is installed on one side of the top of the main beam; a strip-shaped traction main machine is installed at the top of the main machine bottom plate, a traction wheel is installed at the output end of the strip-shaped traction main machine, a car roof rope returning wheel is arranged on one side of the traction wheel, the car roof rope returning wheel is installed at the top of an elevator car, and one end of a main guide rail is installed in a notch formed in one side of the front face of the main beam. Reinforcing ribs are welded to the two ends of the main beam, a notch in the lower portion of the main machine bottom plate and the vicinity of the rope hitch plate. The occupied area in the width direction of the shaft is small, the space utilization rate of the shaft is increased, the supporting strength is improved, the elevator cost is reduced, the device is suitable for large-load elevators, and the market requirement is met.
