The invention discloses a traction machine rear-mounted construction hoist suitable for a building hoistway. The traction machine rear-mounted construction hoist comprises a traction machine, a top beam, a traction medium, a cage and a counterweight. The top beam is fixed to the upper end of the building hoistway, and the traction machine is arranged on a bracket outside the hoistway. A second pulley and a third pulley are arranged on the bracket. The top beam is provided with a fourth pulley, a fifth pulley and a sixth pulley. A first pulley is arranged at the top of the cage, and a seventh pulley is arranged on the counterweight. One end of the traction medium is led out from the traction machine, sequentially bypasses the second pulley, the sixth pulley, the fourth pulley and the firstpulley, and then is led upwards and fixed; and the other end of the traction medium is led out from the traction machine, sequentially bypasses the third pulley, the fifth pulley and the seventh pulley, and then is led upwards and fixed. The hoist has the advantages of being high in safety, convenient to maintain and low in noise.
