The invention discloses a right-angle door-opening machine-room-free elevator system which comprises a steel wire rope, a traction machine, a lift car, a counterweight, a lift car guide rail, a counterweight guide rail, a lift car side rope hitch plate and a counterweight rope hitch plate, and the lift car comprises a car bottom wheel and safety gear integrated device and a car bottom assembly; the car bottom wheel and safety gear integrated device comprises a safety gear, a car bottom wheel, a car bottom main beam and a gantry frame. Longitudinal symmetry planes of the safety tongs, the car bottom wheels, the gantry frame and the car bottom main beam are located on the same vertical plane, longitudinal center lines are collinear on an overlook projection plane, and the safety tongs, the car bottom wheels, the gantry frame and the car bottom main beam are arranged on a shaft diagonal line. The car bottom assembly is horizontally placed on the center line of the car bottom wheel and safety gear integrated device and avoids a rope outlet hole in the car bottom wheel and safety gear integrated device. The problems that in an original arrangement mode, the occupied hoistway area is too large, the door opening range is small, and the guide shoe is seriously abraded due to center eccentricity of the lift car are effectively solved.
